Is there any reason that this airframe wouldn't be legal for use in 3696? The price is certainly right.

If it's OK, I'm probably going to buy a couple and put some of those chinese made outrunners in them.
GWS F4U foamie for 3696?
Moderator: hbartel
I've got one(actually several GWS kits) I've been brainstorming on. The fuselages are pretty close to size, my idea was to use a coro tail group, typical combat style wing and the GWS fuselage. I planned on putting two wooden spars inside the fuse, then fiberglassing the outside. Replacing the wing would take care of a lot of the bad flight characteristics these planes have.
If you planned on using the whole airframe, I'd at minimum install full length spars and cover it with some kind of armor, probably fiberglass, kevlar, or carbon weave. You might could get away with Bi-Di tape and some kind of covering. I'd also check the incidences to fix them-almost all the GWS warbirds have some bad tip stall and trim issues...
It might be a tradoff-you can have a no-sanding required kit for 35 bucks that might not be as durable as a 65 dollar blue foam kit, but pricewise it's almost a 2 to 1 affair. And you can buy replacement wings, fuses, and tail groups from BPHobbies.

Short answer is they are legal for 3696, as long as you get them up to weight.
However, they are white foam and are fragile, so you need reinforce the airframe:
- consider using 1/2 ounce glass and Polycril to toughed up the airfrme and add some weight
- consider replacing the tails with coro or balsa
- some folks have sliced a slot in the wing to add a W shaped spar made of light ply to help strengthen the Corsair wing. Other planes can use 1/16" glass rods.
I am not sure how well the plane would fly at 3696 weights, so before you do a lot of work, you might want to load up the plane with the flight battery and motor, then ballast up to 28 ounces and see if it will fly OK before you spend a lot of time glassing the airframe.
