Please Note the following Caution

CAUTION

A Remote Control (RC) model aircraft is not a toy. It is a flying model that functions much like a full size airplane. If you do not assemble and operate model aircraft properly you can cause injury to yourself and others and damage property. DO NOT FLY a model aircraft unless you are qualified.

You are ultimately responsible for the mechanical, aeronautical and electrical integrity of any model you fly and all of the components that make up the model including but not limited to the airframe itself, control surfaces, hinges, linkages, covering, engine, motor, radio, servos, switches, wiring, battery and parts. Check all components before and after each flight. It is essential that you act with the clear understanding that you are solely responsible for all aspects of the model at all times. DO NOT FLY until it is right.

Tips for Avoiding Common Problems

We have supplied thousands and thousands and thousands of model aircraft in the past 20 plus years. We're not bragging! We tell you this to give some credibility to our suggested list of tips that follow. In talking to modelers around the world, here is what we have found is the key to... 

AVOIDING 90% of PROBLEMS that can arise:  

  1. READ THE CAUTION ABOVE & READ THE LIABILITY DISCLAIMER.You are responsible for all aspects of any model you fly. You're It!
  2. READ ALL DOCUMENTATION before doing anything else! 
  3. INSPECT CAREFULLY immediately upon arrival!.
  4. RETAIN ALL PACKAGING until the checkout is complete! If you need to return anything you must have all of the original packaging.
  5. READ & LOOK! At everything! Do it once & then do it again.
  6. REMEMBER WHAT "ARF" STANDS FOR. ARF means ALMOST Ready to Fly with an emphasis on ALMOST! Some assembly and modeling skills are required.
  7. ALLOW ENOUGH TIME to enjoy the assembly process! Rushing into a 6 hour job with 3 hours to spare simply will not work. This is a Hobby... take your time.
  8. DRY FIT & TEST ASSEMBLE EVERYTHING before you glue anything!
  9. USE 30 MINUTE EPOXY when joining wings & installing stabilizers and other structural components but only after you have dry fitted and test assembled the components without glue! Once parts are glued together they cannot be unglued and they cannot be returned or replaced without charge.
  10. PLAN AHEAD! BE CAREFUL! If you get into trouble, DON'T PANIC. Review everything again, talk it over with an experienced modeler and if still in difficulty consult our Support Services.
  11. TEST TEST!!! TUG TUG TUG!!! EVERYTHING... BEFORE & AFTER EACH FLIGHT! Your model may have been largely pre-constructed and may have pre-installed control rods, hinges, control surfaces and many other essential components. Hinges may have been pinned after they have been installed. However, you must double check every control surface and component before and after each flight. You and only you are responsible for the integrity of all components and the integrity of the model itself. Check everything before and after each flight. Tug on control surfaces, control rods, mounting bolts, T-nuts, mounting plates... tug on everything!
  12. DO NOT OVER TIGHTEN WING BOLTS or other fasteners. You want bolts and nuts snugly tight and if metal you can use a medium grade thread locker such as Pacer Z42 to help them stay tight. Fasteners must be snug and secure. However a model airplane is not a farm tractor or a garbage compactor. You do not need a pipe wrench or an electric drill to tighten up wing bolts or any other fastener. Leave your plumbing and power tools at home.. hand tools only and go easy on the torque... snug and secure... not stripped or torqued until they squeak or break.  Wing bolts can take tremendous torque before breaking... but when you over tighten them or use an electric screw driver on a set of wing bolts, long before the bolts break you can fracture the fuselage, crack the mounting blocks or pull the heads of the bolts through the wing... these problems have a nasty habit of revealing themselves when you least expect the wing to fall off!
  13. DO NOT OVERPOWER ANY MODEL! Stay within the recommended power range for the model. If you overpower the model you run a high risk of structural failure that will lead to loss of control and a subsequent crash that will destroy the model and may cause injury and/or property damage.
  14. ASSUME NOTHING! Remember the old yarn about what happens when you ASS-U-ME something. Check everything repeatedly and frequently and DO NOT FLY any model unless you are satisfied that everything is in good working order.

 

1.1.2. VMA-T210X Twin Otter 09-15 ARF - Supplement to the Manual

1.1.2.1. VMA-T210X Twin Otter 09-15 ARF - Electric Power - Options
Question: My VMAR VMA-T210X Twin Otter 09-15 ARF uses two motors. What do you recommend for a power system?
 
Answer: We have a couple of options for you to consider:
 
1) Our VMAX Power Module for the Twin Otter is #VMM-T210XPM1. This consists of two of our VMAX Brushless Motors (#VMC-120B15VC) and two of our VMAX Electronic Speed Controls (ESC) (#VMC-120B15VC). Each motor and ESC has been factory mounted to a power pylon ready to mate with the wing.
 
2) Our VMAX Power Pack for the Twin Otter (#VMM-T210XPP1) contains the Power Module plus a LiPO battery pack, parallel wiring harness, receiver throttle Y harness and propellers. .
 
Both of these options have been tested with the Twin Otter and help you get into the air quickly and stay there!
 
 
1.1.2.2. VMA-T210X Twin Otter 09-15 ARF - Electric Power - Wiring
Question: My VMAR VMA-T210X Twin Otter 09-15 ARF uses two motors. How should I wire these up so that I can control them from the single throttle channel on my receiver?
 
Answer: The simplest solution is to use our VMAX Power Pack which comes with brushless motors, electronic speed controls (ESC), battery pack, propellors etc and includes a custom made Wiring Harness Set for the Twin Otter power and control system. The Power Pack for the Twin Otter is #VMM-T210XPP1.
 
If you have your own motors, servos, speed controls etc that you intend on using in the VMAR Twin Otter the manufacturer of these electric components is your best bet for advice on operating in a Twin Power configuration. The Wiring Harness Set for the Twin Otter (#VMA-T210XWHS) is available as an aftermarket accessory and in most installations will make it much easier to work with the VMAX Power Module, third party motors, speed controls and servos.
 
If you have purchased the VMAX Power Pack for the Twin Otter (#VMM-T210XPP1) please follow the installation instructions that come with the Power Pack. The VMAX Power Pack will save you hours and hours of time and greatly reduce the chances of making an expensive mistake.
 
If you are using third party power components, follow their instructions. In the absence of specific information from the manufacturer here are some general tips that may assist you. Remember, without specific information from the supplier of your Motors and ESC, you run the risk of doing something wrong and such booboos are usually expensive. Use our tips with this in mind. We can't verify that these tips will work with third party equipment and strongly encourage you to obtain information from the manufacturer of your Motors and ESC.
 
a) Use two idential Brushless Motors and two identical Electronic Speed Controls (ESC). Each motor should have its own speed control. (see footnote below)
 
b) Connect each ESC to a Brushless Motor using the color coded wire as a guide. Test and ensure that the motor turns in the direction expected and that thrust is aft of the motor.
 
c) Make a power Y-connector to feed power from your LiPo battery to the power input leads on both of your ESC's. 
 
d) Use the power Y-connector to connect the power input to the ESC's to a common (1) LiPO battery source.
 
e) Make a throttle Y-connector. This is necessary for DUAL ESC operation which assumes that you are using two motors and two ESC's.
 
For DUAL ESC operation use ONLY the NEGATIVE (-) Power (usually black or brown) & SIGNAL lines
(see table below) between the receiver throttle channel and the ESC's.
 
Do NOT use the POSITIVE (+) Power (usually Red) wires.  
The following table serves as a guide to common radio systems and their wiring schema and color usage. Use this table with caution. If in doubt, please defer to information provided by your radio supplier.  
 
RADIO BRAND NEGATIVE (-) SIGNAL
VRS & Futaba Black White
Airtronics Z Black Blue
JR Brown Orange
HiTec Black Yellow
f) Plug the ESC throttle control wires into the ends of the throttle Y-connector
 
g) Plug the remaining single end of the throttle Y connector into your receiver throttle channel.  
 
h) Use the airborne battery pack from your radio system to power your receiver. Do NOT attempt to use power from either BEC to power your receiver. You may wish to consider using a stand alone BEC such as that from Western Robotics to power your radio system but do NOT use the BEC's that are a part of many ESC's. They will not work in a twin power configuration.
 
i) Select suitable propellers for your motors and your speed controllers. The two props should be identical. Prop selection is vital with brushless motors. Overloading the motors and ESC by using the wrong prop can get very very expensive in a big hurry.
 
j) Verify that you can control the RPM of the motors via the receiver and that they produce similar RPM and thrust throughout the throttle range.  
 
Footnote: There are some dual ESC's that enable you to control two Brushless motors from one ESC. These eliminates the need for a second ESC and may make the installation of third party components simpler. If you are using a dual ESC, ensure that you follow the manufacturers instructions regarding wiring and operations.
 
 
 
1.1.2.3. VMA-T210X Twin Otter 09-15 ARF - Wing - One Piece or Two?

Question: My VMAR VMA-T210X Twin Otter 09-15 ARF refers to a one piece wing. The Twin Otter I received has a two piece wing. What's the story here?

Answer: In some markets, shipping carriers such as UPS charge an additional surcharge for longer boxes. In these markets we have reduced the length of the box by shipping the wing in two pieces in order to save the end consumer from having to pay surcharges on freight.

Additional Information:  If your wing was shipped in two pieces, use the wing joiner and 30 minute epoxy to join the wing halves. A roll of wing joint tape has been supplied to seal the joint after the epoxy has cured. USE ONLY 30 MINUTE EPOXY when joining wing halves.  
 
A subsequent article provides detailed instructions for joining the halves of two piece wings.
 
1.1.2.4. VMA-T210X Twin Otter 09-15 ARF - (Stage 0) Wing Assembly - Joining the Wing Halves
 
In some markets we have reduced the length of the shipping box by shipping the wing in two pieces in order to save end consumers from having to pay surcharges on freight. The Assembly and Operations Manual (version 20061031) does not include instructions for joining the wing halves.
 
If your wing was shipped in two pieces, BEFORE BEGINNING Stage 1 of the Assembly and Operations Manual please COMPLETE THE FOLLOWING "Stage 0" INSTRUCTIONS in order to assemble your wing.
 
Parts Supplied:
- Right and left wing panels
- Wing joiner (also called dihedral brace)
- Roll of wing joint tape
Tools & Adhesives needed:
- 30 minute epoxy. Pacer Zepoxy #PAC-30ZPOXY8
recommended. (Do not use 5 Minute Epoxy)
- Epoxy brush or stir sticks
- Disposable mixing dish for the epoxy
- Sandpaper (Coarse 240 grit recommended)
- Low tack masking tape
- Pencil, knife and ruler
- Paper towels

Step 0.1 Locate the wing joiner (also called Dihedral brace). Use a ruler, determine the center of the wing joiner and mark a center line with a pencil as illustrated in 0B.
 
Step 0.2 Locate the wings (See 0A). Trial fit the wing joiner in the channels in the wing panels. You will see two channels in each wing. The channel closest to the leading edge should NOT be used. Insert the wing joiner into the channel that is slightly further aft in the wing. The wing joiner should insert smoothly up to the center line as illustrated in 0C.
 
Now slide the other wing panel onto the wing joiner until the panels meet. If the fit is overly tight, sand the wing joiner slightly and try again. Do not apply excessive force. Sand the joiner until a snug fit is obtained. If the panels slide onto the joiner relatively easily but you end up with a slight gap between the wing panels, trim the ends of the joiner by about 1/8 in. (3 mm) and try again. Work in small steps, testing the results between steps.
 
Mark the joiner to indicate which way is UP as illustrated in 0B.
 

0A - Left & right wing panels

0B - Preparation of wing joiner

Step 0.3 Apply plenty of 30 minute epoxy to all sides of one end (half) of the wing joiner using a stir stick or epoxy brush as illustrated in 0D. Carefully insert the epoxy coated half of the wing joiner into one wing panel as illustrated in 0E. 
 
See 0F and use a cloth or tissue to wipe away any excess epoxy that squeezes out of the joint.
 
Repeat this process several times to ensure the wing joiner and cavity are well coated with 30 minute epoxy.
 
When the wing joiner and cavity are well coated with 30 minute epoxy, insert the joiner to the center line, wipe way any excess epoxy and let dry. (Note: do not use 5 minute epoxy or CA to join the wings).
 

0C - Trial fit the wing joiner

0D - Apply plenty of 30 minute epoxy to the wing joiner

0E - Carefully insert the joiner all the way to the center line

0F - Wipe off the excess epoxy then allow to cure
 
Step 0.4 When the epoxy holding the wing joiner into the first wing panel has cured, trial fit the second wing panel onto the wing joiner (do not glue without trial fitting first) to ensure that the two wing panels fit without an excessive gap.
 
Step 0.5 Now apply plenty of 30 minute epoxy to all sides of the exposed half of the wing joiner (see 0G). Use only 30 minute epoxy to ensure a strong bond and to give yourself plenty of working time. As described in step 0.3, repeatedly apply 30 minute epoxy to the joiner and insert the joiner into the wing joiner cavity to ensure that the wing joiner and the cavity are well coated with 30 minute epoxy.
 
When you have worked plenty of epoxy into the wing joiner cavity, pull the joiner out of the cavity one last time and apply plenty of 30 minute epoxy to the wing root ribs of both panels. Slide the wings together until the wing roots are firmly in contact with each other and there is no gap remaining between the wing panels (see OH). Epoxy should ooze from the joint and be cleaned off with a rag or tissue before it cures.
 
Step 0.6 Use low tack masking tape (see 0I) to align the wing surfaces and to hold the wing panels firmly together until the epoxy cures.
 

0G - Apply plenty of 30 minute epoxy to all surfaces. 

0H - Align the two wing panels and slowly close the gap until the wing roots are firmly in contact with each other.

0I - Use low tack masking tape to hold the wing panels tightly together until the epoxy has completely cured.


Step 0.7  Once the epoxy has cured completely (allow several hours at least), the masking tape can be carefully removed from the wing panels. Peel the tape back on itself... do not pull upright away from the wing.
 
To seal and finish the joint between the wing panels, a roll of wing joint tape has been supplied. Starting on the bottom side of the wing, stick the tape centrally over the joint (see OJ) ensuring that the wing joint tape is pressed down firmly as you work around the wing. Wrap the wing joint tape all the way around the wing in one piece (see OK), starting and finishing on the bottom of the wing (see OL). Trim off any excess tape using a sharp knife.
 

0J - Apply wing joint tape over the joint starting here on the bottom.  

0K - Continue applying the tape over the top of the wing, pressing down firmly as you go.  

0L - Continue back around to the bottom of the wing & overlap the tape where you started. Trim off excess tape.  

NEXT STEPS:

If you are installing a VMAX Power Pack or VMAX Power Module or VMAR Wiring Harness Set, please review the instructions that were supplied with these items now.

Otherwise once you have joined the wing halves, please proceed to Stage 1 of the Assembly and Operations Manual to continue with the assembly of your model.

Pictures are intended to illustrate components and methods of assembly. Production components may vary in detail from that shown.

1.1.3.1. VMA-T210X Twin Otter 09-15 ARF - Covering

This model uses POLYCOTE ECS Covering

POLYCOTE ECS - Care & Maintenance - Quick Tips

Question: Do you have any pointers regarding the Care & Maintenance of POLYCOTE ECS?

Answer: Yes we have this Summary of Quick Tips. See www.richmondrc.com ( Enter Site > Support Services > Knowledge Base then Search on "Covering") for an expanded explanation of each Tip.

Polyester offers the best in covering performance and as with any new modern technology, the maintenance methods may be different than those you used with your older covering. This is NOT Monokote or Solarfilm, its different. If you have used ORACOVER or ULTRACOTE you will have some experience with working with POLYESTER as a covering material.

Here is our Summary of Quick Tips related to POLYCOTE ECS covering.

  • Avoid Hot Vehicles
    • Cooking your model in your vehicle for hours on end is generally not a good idea! Temperatures can easily exceed 50C (122 F) under such conditions. You will get sags. Consult our Knowledge Base before attempting to remove sags.  
  • Cleaning After Flying
    • We recommend Fantastic household cleaner and disposable paper towels. Mist, do not flood. Wipe along seams, not across. Do NOT NOT NOT NOT use SIMPLE GREEN, 409 or similar materials for cleaning a model airplane.
  • Cleaning Initially
    • Upon initial inspection if you see a thin streaky film on any of the POLYCOTE ECS, work outdoors and use a paper towel and wipe a slightly wet film of Mineral Spirits over 1/4 of a wing or half a fuselage at a time. Rub gently while still wet. Change towels frequently. Avoid plastics.
  • Cutting
    • Use sharp scissors or an XACTO knife with a sharp #11 blade.
  • Pealing
    • Relatively rare. Fix as soon as possible. Consult our Knowledge Base before attempting to resolve.
  • Protecting the Finish
    • Most Importantly - Follow the cleaning instructions. Use the recommended cleaners and method. Dab away raw fuel. Test small out of the way area and all plastics before applying any glue, solvent, cleaner, paint or other preparation. Patch punctures promptly. Avoid hours and hours sitting in the direct sun.
  • Removing & Using Tape
    • Use low tack tape. When removing tape , peal the tape back on itself parallel to the surface of the covering.
  • Repairing Punctures
    •  Patch promptly. Clean any oil residue from the area of the puncture. Patch should be 1/2" (13mm) bigger on all sides. Round the corners. Seal in place with a heat iron & sock. Tighten area with a Heat Gun.
  • Resealing Seams
    • Act promptly. Clean any oil residue from the area and reseal the seam with thin CA.
  • Tightening Sags
    • Remember SSB... SECURE the perimeter then SHRINK to fit then BOND to the structure. Use an iron with sock to SECURE the perimeter, use a heat gun to SHRINK within the perimeter, use a soft cloth while the covering is warm to BOND the covering to solid substrates.
  • Tools for Working with POLYCOTE ECS
    • Scissors, XACTO with #11 blade, iron, iron sock, regulated heat gun, soft cotton cloth or glove.

1.2. VMA-T210X Twin Otter 09-15 ARF - Additional Information

In general "Additional" Information is:

  • In addition to that found in other documentation related to this product,
  • Often reflects feedback &/or questions from users of the product.

Subject to the Conditions of Use, please review the attachments and related articles listed below.

COPYRIGHT
Copyright Richmond RC Supply Ltd. All rights reserved.
 
1.2.1. VMA-T210X Twin Otter 09-15 ARF - Aileron Control Rod Length
Question: The aileron control rods that run from the servo to the aileron control horn on my VMAR Twin Otter appear to be slightly too long. What should I do?
 
Answer: The Twin Otter wing has been produced in several different configurations depending on the market area. Early production runs shipped to Europe and the UK used a one piece wing. Later production runs and all shipments to North America used a two piece wing. The aileron control rod length is adjustable to fit the wing that you have.

For each aileron:

1) Ensure that your servo is mounted correctly and that the servo arm can rotate freely the way you have installed it. Center the servo arm so that it lies parallel to the wing trailing edge.

3) Install the control horns on the ailerons. Tape the ailerons into a neutral position as explained in the manual.

4) If you find that the aileron control rods are too long, use a ruler to measure how much shorter you need to make the rod.

  • From one end of the rod, unscrew the clevis and threaded stud.
  • Use a pair of scissors or snips to cut the plastic rod to the shorter length you required.
  • Thread the stud and clevis back onto the plastic rod.
  • Tug test to ensure you have a secure coupling.

5) If in any doubt about the security of the coupling, unthread the clevis and wick thin CA into the coupling between the stud and the plastic tube. Do not get CA into the clevis threads.

1.2.2. VMA-T210X Twin Otter 09-15 ARF - Extra Hardware Items
Question: I have completed the assembly of my VMAR Twin Otter and I have a few extra hardware items such as horns, screws and wing bolts. What are these for?
 
Answer: We usually include a few extra horns and wing bolts with all VMAR ARF's. You may also find a spare clevis and a couple of small screws depending on the model. These are free and intended to help you out if you drop or misplace one of these small items. If you have followed all of the assembly steps, completed your model, tested that your radio and control surfaces all move correctly, tug tested everything twice, just put any of extra hardware pieces in one of the bags and set it aside as spares just in case you need them later on. Don't throw anything out, you just never know when that screw, horn or nut may be needed!
1.2.3. VMA-T210X Twin Otter 09-15 ARF - Pilots - What sizes fit?
Question: Can pilots be installed in the VMAR Twin Otter? If so what are the dimensions that I should keep in mind when selecting pilots?
 
Answer: Yes pilots (2) can be installed in the VMAR Twin Otter. The factory seats and shoulder harnesses are installed and the seats have a flexible back that facilitates installation of after market pilots working from inside the main radio bay of the fuselage. Here are some approximate dimensions for reference purposes when selecting pilots.
    • Top of head to seat cushion = 3" max
    • Back of seat to back of knee = 2-1/2" max
    • Back of seat to front of knee = 3-1/8" max
    • Seat cushion to bottom of feet = 2-1/4" max
    • Width of hips and shoulders = 2" max
1.2.4. VMA-T210X Twin Otter 09-15 ARF - Glow Power - Tips
Question: Can I use glow engines to power my VMAR Twin Offer? If so what sizes are recommended? Any tips you can suggest on what I need to plan for? 
 
Answer: Yes the VMAR Twin Otter can be powered with glow engines. We suggest glow engines be at least .09 cu. in. each as a minimum. Maximum engine size should be limited to .15 cu. in. each. Please note that setting up and operating multiple glow engines is not for novices. It requires considerable expertise with modeling, glow engines and RC flying to be able to successfully equip and fly the Twin Otter with glow engines.

Tips on use of glow power:
 
1) We recommend two stroke engines for this model. Four stroke engines tend to be bigger and heavier and they may cause structural failure of the standard wood engine mounting pylons.
 
2) You will need to plan your fuel tanks and engine mounting system with careful consideration for physical space particularly if you wish to try to install the engines so that you can utilize the scale like engine shrouds and nacelles.
 
3) Do NOT glue the engine mounting pylons (factory assembled of wood) to the wing until you have test fitted the engine mounting pylons, engine mounts, engines, mufflers, fuel tanks, fuel tubing, throttle linkages, engine shrouds and nacelles.
 
4) Once you have test fitted all of the components related to the glow engines, use 30 Minute Epoxy to attach the engine pylons to the wing. Ensure they are aligned and fitted properly. Let the adhesive cure thoroughly before proceeding.
 
5) Use Pacer Finishing Resin and a brush to throughly seal any exposed wood, particularly that of the engine mounting pylons and the attachment area on the wing. Also the wing saddle area. The exhaust from glow engines contains lots of hot vapourized and liquid oil residue. Although most of this oil will be channeled out in the exhaust, some oil will inevitably get on the model itself and will be absorbed by any unsealed wood. Oil can weaken glue joints and the wood itself.
 
6) Glow engines tend to produce considerable vibration particularly in a twin configuration when the engines are not quite at the same RPM. Take particular care to balance your props and to run the engines at the same RPM when compared to each other throughout the range of throttle positions. Vibration can cause fuel feed problems, lean runs and engine cut off as well as structural failure, control surface flutter and/or separation and is very damaging to servos. It is very important to keep vibration to a minimum.
 
 
 
 
1.2.5. VMA-T210X Twin Otter 09-15 ARF - Steering Control Rod for Nose Gear
Question: Where is the steering control rod for the nose gear packed for shipping? What does it look like? I can't seem to locate it. Also, please provide any tips you may have for installing it.
 
Answer: The Twin Otter steering control rod for the nose gear is shipped in the fuselage main radio and forward bay. It is usually located near the left side. The rod is about 15.75 in. (654 mm) long. The inner rod is solid metal and the outer (shorter) rod is a semi transparent plastic tube. There is an EZ connector near the servo end of the metal rod and a Z-bend at the steering arm end of the metal rod.

Installation is described in the manual that came with the model and can be summarized as follows:

1) The Z-bend engages with the steering arm. The EZ connector attach's to the servo arm and the metal control rod.
 
2) Loosen the EZ connector set screw and remove the EZ connector from the metal rod.
 
3) Remove the steering arm from your servo.
 
4) Attach the EZ connector to the servo arm using the nut to fasten it.
 
5) Slide the EZ connector onto the metal steering control rod leaving the servo arm attached. 
 
6) Attach the servo arm to the servo. Align the nose gear and steering servo in a neutral position for straight ahead motion. Secure the servo arm to the servo.
 
7) Tighten the EZ connector set screw to engage the steering control rod.
 
8) Leave about .5 in (12 mm) of extra rod protruding beyond (aft) of the EZ connector. Snip off any excess length.
1.2.6. VMA-T210X Twin Otter 09-15 ARF - Steering Direction sync with Rudder Direction
Question: I am using a Y-harness in my VMAR Twin Otter to enable control of the rudder and the nose gear steering using the rudder channel on my receiver. Will this automatically result in the steering direction on the ground using the nose gear being in sync (the same direction) as the rudder steering in the air?
 
Answer: It depends on your servo type and installation but in any event it's easy to sync the nose gear and rudder steering so that they are both moving in the correct direction even though you are controlling the two servos via a Y-harness from the rudder channel of your receiver.

1) First of all try it out. If the nose gear is moving in sync with the rudder you are good to go.

2) If they are not in sync please see your Assembly and Operations Manual. Look at pictures 12C and 12F and the picture in the Stage 12 introduction. Picture 12F shows the rudder control rod attached to the servo steering arm that is pointing up. To reverse the direction of the movement of the rudder move the rudder control rod to the opposite side of the rudder servo.

3) OR you can do the following: See pictures 20B, 20C, 21.1 and 21.2. These show the steering control arm connected via an EZ Connector attached to the left side of the steering servo arm. To reverse the direction of movement of the steering nose gear move the steering control rod and EZ Connector to the opposite side of the steering servo.
