Stage 1 - Install Power Pylons - For VMA-J210X JU52 Trimotor
 
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.
