Acro Wot - Instructions

STEP 7

Prepare your aileron servos by connecting a suitable 300mm extension lead to 
each. It is a good idea to use a lead-lock, a turn of insulation tape or heatshrink 
tube over the joint for additional security.

STEP 8

Pilot drill the servo mounts, then screw the aileron servos in position using the 
mounting screws, rubber grommets and ferrules supplied with your radio. Note 
that the output arms face towards the rear of the wing.

STEP 9

Prepare the aileron pushrods by screwing on a nylon snap link and fuel tube 
keeper. Locate the aileron control horns. They are screwed in position on the 
ailerons in line with the aileron servo's output 
arm. Align the row of holes in the horn 
with the hingeline. Mark and pilot drill two 
mounting holes then screw the horn to the 
aileron. The screws thread into the moulded 
horn plate on the top surface of the wing.

STEP 10

Do not overtighten the control horn mounting screws - you don't want to crush 
the aileron. Turn the model over and trim off any excess thread using side 
cutters. Note that we have fitted short lengths of fuel tube over the clevis to 
ensure it cannot open under flight loads.

STEP 11

Use a small length of tape to hold each of the ailerons at their neutral position 
while you complete the aileron linkages. Ensure that both aileron servos are 
centred. With the pushrod connected to its horn, mark the position the control 
rod passes over the servo’s output arm. Bend the pushrod up at 90° at this 
point.

STEP 6 

Protect the covering with masking tape, then spread sufficient epoxy over the 
opposite panel joiner slot, wing joiner and root rib. Bring the two panels together 
ensuring the epoxy fills the join. Wipe off any excess that squeezes out of the 
joint, then use tape to hold the panels together as the adhesive cures.
