a) Review the Read Me First documentation and the Assembly & Operations Manual that came with your model.

 

b) Not Applicable

 

c)  Complete Stage 1 from the Assembly & Operations Manual.

 

d) Complete Stage 2 from the Assembly & Operations Manual. Note that in some markets the power pylons have been pre-attached to the wing by the factory.

 

e) Once you completed Stage 2 from the Assembly & Operations Manual you will have an assembled wing with power pylons attached to the wing.

 

f) Complete Stages 3 to 8 from the Assembly & Operations Manual.

 

g) Review Stage 9 of the Assembly & Operations Manual. Skip step 9.1 and replace steps 9.2, 9.3 and 9.4 with the following procedure.  

 

h) Look carefully at the wing power assemblies provided with this Power Module set. Consult figures 9C, 9E and 9F in the Assembly and Operations Manual provided with your model.

 

For each wing motor in turn,

 

i) Remove the four loosely fitted nut, bolt and washer sets from the wood motor mounting plate.

 

j) Remove the long black tapered head screws from the back of the wood motor mounting plate.

 

k) Fit the motor mounting plate (with motor) to the power pylon using the two long black taper head screws as shown in Figure 9E of the Assembly and Operations Manual. Leave slightly loose for now. Orient the mounting plate so that the motor wires will pass through the slot in the power pylon as shown in figure 9B, 9F and 9G of the Assembly and Operations Manual.

 

l) Insert the four nut, bolt and washer sets through the wood motor mounting plate and through the power pylon as depicted in Figure 9F of the Assembly and Operations Manual. We suggest having the nuts at the back of the pylon (opposite to that shown in Figure 9F).

 

m) Tighten the two long black taper head screws and the four nut and bolt sets and ensure the motor mounting plate is securely attached to the power pylon.

 

n) Apply medium strength (blue) thread locker such as Pacer Z42 to the nuts to prevent them from vibrating loose.

 

o) Repeat steps i) through n) for the second wing motor.

 

p) Install three (3) motor extension wires for each wing motor per Figures 9G and 9H of the Assembly and Operations Manual. Note that although the wires may appear to be the same color, there are labels near the female (motor) ends of each wire that direct which wire is to be attached to the red, black and white ESC wires respectively. WORK WITH ONE WIRE AT A TIME. Feed each wire separately from the motor pylon access holes in the upper surface of the wing. Feed the male end of each wire down through the access hole and into the wire guide tube until it exits the tube and enters the large access cavity at the center of the wing. Connect each motor extension wire to the appropriate speed control wire for each wing motor per Figure 9I of the Assembly and Operations Manual and per the label attached to the motor end of each extension wire. It is important to work with one wire at a time and to follow the intent of the labels. 

 

In summary:

• The red ESC wire connects to the red motor wire.
• The black ESC wire connects to the white motor wire.
• The white ESC wire connects to the black motor wire.

 

r) Review Stage 9, Figures 9K, 9L and 9M and then secure the pre-assembled fuselage engine pylon to the fuselage.  

 

a) Review the Read Me First documentation and the Assembly & Operations Manual that came with your model.

 

b) Not Applicable

 

c)  Complete Stage 1 from the Assembly & Operations Manual.

 

d) Complete Stage 2 from the Assembly & Operations Manual. Note that in some markets the power pylons have been pre-attached to the wing by the factory.

 

e) Once you completed Stage 2 from the Assembly & Operations Manual you will have an assembled wing with power pylons attached to the wing.

 

f) Complete Stages 3 to 8 from the Assembly & Operations Manual.

 

g) Review Stage 9 of the Assembly & Operations Manual. In particular consult figure 9I of Assembly and Operations Manual. We suggest that in lieu of Figure 9I that you instead arrange the two wing ESC's as follows:

 

h) See Figure 2A. Note the orientation and position of the two speed controls. In particular note that the ends of the ESC with the motor power wires are partially positioned into the wing bay cavity adjacent to the large open cavity at the center of the wing.

 

 

i) You will find a wooden block with a slot, zip strapped to each wing ESC. AFTER installing all wiring and before flying your model, use ZAP-A-GAP or ZEPOXY to attach the blocks to the floor of the large cavity at the center of the wing, oriented and positioned as shown in Figure 2A. If you need to remove the ESC's at a later date you can cut the zip strap to remove the ESC and then re-install the ESC using a new zip strap.

 

a) Review the Read Me First documentation and the Assembly and Operations Manual that came with your model. Continue with the assembly procedures provided therein.

 

b) When you are ready to complete Stage 9 of the Assembly and Operations Manual pause and review Figure 9N and these notes carefully.

 

c) Stage 9 of the Assembly and Operations Manual covers the installation of the electric motors and speed controls. In effect by purchasing a VMAX Power Module you have avoided much of this work and in earlier stages of these instructions pertaining to this VMAX Power Module you have installed the factory assembled power pylons to the wing and the fuselage and extended the wiring from the wing motors to their respective speed controls in the center section of the wing.

 

d) You will need to complete the wiring.

• If you have purchased the VMAR Wiring Harness Set for this model (VMA-J210XWHS) please see the detailed wiring instructions provided therein.
• If you do NOT have the VMAR Wiring Harness Set for this model you will need to use your own wiring setup. Make sure whatever you do is compatible with your radio system, your servos, your battery and the speed controls.
  • Note: Modelers who are not experienced with multi-motor electric flight systems are strongly encouraged to use the VMAR Wiring Harness Set applicable to their VMAR multi-motor model. Scratch building and installing a reliable wiring harness set for a multi-motor electric model requires approximately 8 hours of work & considerable knowledge and experience.    
• Figure 9N of the Assembly and Operations Manual shows a generic wiring schematic that may be helpful. Be particularly careful with the thin red wires coming from the Electronic Speed Controls (ESC).  Figure 9M shows only the Negative (-) and Signal  wires from each speed control connecting to the throttle channel of the receiver. This may or MAY not be suitable for your receiver. You will need to nail this down before connecting anything. The most common setup today is to NOT hook the thin red wires from the ESC to themselves or anything else. Just work with the Negative (-) and Signal wires from the ESC's all the way to the throttle channel on your receiver.
• To add some complexity to the ESC wiring, there is no standard color schema used by all radio manufacturers. Caution is a must. To help you design and connect your wiring please see the generic wiring information provided in the Read Me First information that came with your model and reprinted below for your convenience. This should be considered a guideline only.
  • Note: There are some risks here and if you are not electronically inclined you should get help and consider purchasing the VMAR Wiring Harness Set for this model.  

a) Use three idential Brushless Motors and three 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 Y3-connector to feed power from your LiPo battery to the power input leads on both of your ESC's. 

 

d) Use the power Y3-connector to connect the power input to the ESC's to a common (1) LiPO battery source.

 

e) Make a throttle Y3-connector (you can serially gang up two Y connectors). This is necessary for Triple ESC operation which assumes that you are using three motors and three ESC's.

 

For TRIPLE 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 Y3-connector

 

g) Plug the remaining single end of the throttle Y3 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 triple power configuration.

 

i) Select suitable propellers for your motors and your speed controllers. The three 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.
