ParkZone P-47
At the root end of the flap a Zona saw (above left) with a good sharp 32-tooth razor blade cuts the kerf that frees that end of the flap. The ParkZone SV-80 servo fits perfectly in the molded flap servo pocket (above right). Note the run
of the aileron, flap, and retract servo cables in the wing channel. The retainer on the elevator clevis (below left) is absolutely essential. This is the hardware that comes with the P-47 (below right) and includes the flap horns and pushrods.
justing the axles to the right length on the strut so the wheels nest in the wells without any friction. The manual does suggest a length of 130 mm. I set the wheels in the wells and then let the axle piece slide freely on the gear strut. Then I placed the retract in its mount and the axle in the wheel hub, and screwed the retract in place. That basi- cally aligned everything until later when the retracts were operated to determine any finer adjustments.
At this point there were a number of servo
cables that had to go into the root of the wing and eventually connect to the receiver in the fuselage. A piece of silver colored tape
lays over a channel in the wing that already has the aileron servo cable running through it. It is possible to nest the other two cables, the one for the flap and the one for the re- tract, in this same channel but it has to be done carefully, with each cable set “on edge”. The place where some carving has to be done is at the root, both inside and out. Some of the wing channel, right at the root has to be cut away, and the hole for the cables inside the root enlarged. Using a knife to do this risks nicking or cutting a ca- ble. What does work is a narrow blade screwdriver that’s used to poke bits of the foam away. There’s nothing cosmetic here
to worry about, only making the hole just large enough to get the servo connectors through.
Once all that’s finished, and the cables
nested neatly in place, the replacement tape included in the kit can be laid over the servo cable channel. With that done, 90% of the assembly is complete. Only things left are the horizontal stab, which is a plug-in, the clear plastic belly skid, and the retract doors. That will take all of 10 minutes. With the P-47 ready to fly a few preflights were in order to insure a trouble-free maid- en flight. The c.g. was checked—with bat- tery in place!—and it was right in spec at 60
Some Model Master Silver acryllic paint (above left) from Testors almost perfectly matches the silver of the airframe and was used to touch up the foam
54
where it had been cut away. The E-flite .15–.25 size electric retracts (above right) drop perfectly into position. The gear doors snap in place.
