1.1. VMA-P210X PC9 & Texan II 06-12 ARF - Control Rod Length - Adjusting

Question: Can I adjust the length of the control rods in my model? I want to use my existing servos and shift one servo slightly and when I do that the rods seem slightly too long. What should I do?

Answer: Most VMAR models use an inner and outer plastic rod system for the control rods. At each end, the plastic inner rod usually couples to a threaded metal rod which in turn connects to a clevis.

1) Slightly Longer Control Rods: You can make the control rods slightly longer by adjusting the position of the clevis on the threaded metal rod at each end. Do not over do it or the clevis could come off under load. Tug test to ensure you have a secure coupling after any adjustment.

2) Much Longer Control Rods: You will need to change either the metal threaded rods at each end (we have these in stock in various lengths) OR cut the inner plastic rod and splice an additional piece of the splined plastic rod into place. Use 2mm threaded metal studs as couplers. Tug test to ensure you have a secure coupling after any such modification.

3) Shorter Control Rods: You can make the control rods slightly shorter by adjusting the position of the clevis on the threaded metal rod at each end. Tug test to ensure you have a secure coupling after any adjustment.

To further reduce the control rod length:

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.

4) If in any doubt about the security of any 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. VMA-P210X PC9 & Texan II 06-12 ARF - Extra Hardware Items

Question: I have completed the assembly of my VMAR Nouvo 1300 EP 51 in. Electric ARF 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!

1.3. VMA-P210X PC9 & Texan II 06-12 ARF - Glow Power - Tips

Question: Can I use glow engines to power my VMAR PC9 & Texan II 06-12 ARF? If so what sizes are recommended? Any tips you can suggest on what I need to plan for?

Answer: Yes the VMAR PC9 & Texan II 06-12 ARF can be powered with glow engines. We suggest glow engines be .06 to .12cu. in. Please note that this model has been intended primarily for Electric Flight and does not come with a tank or engine mount. It does however utilize the VMAR power module system which makes it easier to modify the propulsion system to glow.

Tips on use of glow power:

1) We recommend two stroke engines for this model. Four stroke engines tend to be bigger and heavier.

2) You will need to plan your fuel tank and engine mounting system with careful consideration for physical space particularly if you wish to try to install the engine so that you can use the cowl

3) Use Pacer Finishing Resin and a brush to throughly seal any exposed wood, particularly that of the firewall, the power module forward firewall 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.

4) Glow engines tend to produce considerable vibration particularly if the propellor is not balanced correctly. Take particular care to balance your propellor. 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.

1.4. VMA-P210X PC9 & Texan II 06-12 ARF - Stage 11 Installing Electric Motor and ESC - Step 11C Mounting Screw (Bolt) Set

Question: Stage 11 Step 11C of my P210X Manual refers to installing four bolt and washer sets for mounting the motor. These bolt sets are stated to come with the kit but I did not get these in my kit. What's the story here?

Answer: The reference to the bolt sets (mounting screws) in your version of the P210X Manual is incorrect. These mounting screws come with the Power Module and Power Pack but are not included with the kit. Each motor is different and requires different mounting hardware and methods. We do provide a blank firewall set that can be drilled to suit nearly all motors.

Mounting Screws - What to use on VMM-111B18VM VMAX Brushless Motor

Question: I have a VMAX #VMM-111B18VM VMAX Brushless Motor. What do I need in the way of mounting screws?

Answer: There are a several options for this depending on what you have in mind:

a) VMAX VMAX #VMM-111B18VM VMAX Brushless Motors that are supplied with VMAX Power Modules and VMAX Power Packs come pre-mounted with the appropriate screws for the motor.

b) The threads are 3mm and generally four 3mm x 6-12 mm machine hex head screws with washers will work.

c) We sell a Mounting Screw Set (#VMM-111B18MS) consisting of four 3mm x 10mm hex head screws. Hex head screws should be used with flat washers under the heads.

d) We also sell a Mounting Screw Set (#VMM-111B18MT) consisting of 16 mounting screws. Four screws in each of four different sizes/styles.

3 x 10 mm Hex head machine screws (4) (like VMM-111B18MS)
3 x 16 mm Hex head machine screws (4) (longer version of above)
3 x 6 mm Phillips countersink head screws (4) (for flush fitting)
3 x 10 mm Phillips countersink head screws (4) (for flush fitting)

The four different sizes/styles allow for thicker firewalls, multi-layer firewalls where the screw heads must be countersunk between the layers, etc.

This set provides for a very wide range of different mounting methods.

Hex head screws should be used with flat washers under the heads.

CAUTION: When mounting motors using any method, ensure all fasteners are tightened securely. Check for vibration free operation of the motor. If not vibration free, reseat and retighten all fasteners and ancilliary components such as props and gears. Tighten fasteners firmly but don't strip the threads. Use medium strength thread locker on all metal to metal fasteners.
