Things You'll Need
Instructions
Examine all the glued joints on your almost-ready-to-fly, or ARF, Piper Cherokee. All the joints should feel solid when you twist and tug them a little bit.
Inspect the aircraft covering. Most ARF kits include a "skin" covering on at least part of the airplane. Make sure there are no loose or lifting edges. If there are, glue them down with epoxy.
Reinforce the wing joint. The Piper Cherokee has a wing attached to the bottom of the fuselage, so it absorbs a lot of force, but for packaging purposes, manufacturers may split the wing. When you join the wing halves, carefully peel back the wing covering with the craft knife and use epoxy on the wood joint, then reinforce it with a strip of nylon tape on top and bottom. Add more epoxy on the tape's leading edges, let dry for an hour, then put the covering back in place.
Apply wood sealant with a small brush to the engine mount if you are using a glow plug engine. Otherwise, fuel may soak the wood and destabilize your engine in flight. Also, because the nose gear is directly under the engine, a fuel-soaked engine mount could cause problems with landing.
Check all control surfaces to make sure they are firmly attached. If an aileron or other control surface falls off in flight, it could be fatal to your RC plane.
