Finish The Wheel Wells - Top Flite P-47D Thunderbolt User Manual

❏
2. Use 30-minute epoxy to glue the servo
mounting blocks to the inside of the hatch covers. Be
certain the servos are positioned on the covers
according to the plan and that the servo mounting
blocks will not interfere with the hatch cover
mounting rails.
❏
3. Secure each servo mounting block to the hatch
cover with a #2 x 3/8" flat head screw. Permanently
install the screws with CA or epoxy.
❏
4. Cut a slot in the aileron servo hatch covers for
the servo arm.
Refer to this photo for the following four steps.
❏
5. Determine the location of the die-cut 1/8"
plywood control horn mounting plate on the
bottom of the right aileron. Cut into the bottom of the
aileron to accommodate the die-cut 1/8" plywood
mounting plate, then glue it into position just the
same as you did for the elevators and rudder.
❏
6. Use four #4 x 1/2" screws to mount a control
horn to the mounting plate.
❏
7. Connect the aileron to the aileron servo with a
pushrod made from the hardware shown on the plan
and in the photo (one of the 12" pushrods is the one
with a threaded end leftover from hooking up the
rudder). Be certain to use silver solder and don't
forget to wipe away residual soldering flux right after
the solder has solidified. Coat the pushrod and the
clevis with a film of oil to prevent rusting.
❏
8. Hook up the left aileron the same way.
❏
9. Make the flap pushrods from the hardware
shown on the plan. For most servos the length of the
pushrods will be the same as shown on the plan.
Temporarily connect the flaps to the flap servos with
the pushrods.
Note: Don't forget that the flap servos are not
centered, but the servo arms are forward when the
flaps are retracted (up).

Finish the wheel wells

1. Using the right wing plan as a guide, cut the
opening in the bottom of the wing to accommodate
the landing gear. Start by cutting a small hole, then
carefully enlarge it until you can get the gear in.

2. Temporarily mount the right landing gear in
the wing. Cut the wheel well opening and the ribs so
the gear can be retracted. Just the same as you did
in the previous step, start with a small hole and
carefully enlarge it until you can retract the gear. A
Dremel moto tool with a Robart 90-degree adapter
and a sanding drum is a useful tool to neatly trim the
ribs to accommodate the wheel.
❏
3. Fit the left landing gear and wheel in the wing the
same way. Reinforce the unsupported sheeting around
the wheel opening by laminating leftover 1/16" cross-
grain balsa to the inside of the bottom sheeting.
