Just bought a Great Planes P-47 Thunderbolt from TowerHobbies. It's the 39.5 inch wingspan version.

I am looking to change the fixed landing gear with retracts. The problem is: a) I don't really know what size of retracts to get.

b) I could not find any of those plastic inserts that you cut into the wing so when that the wheels would fit into when retracted.

Anyone know of any retract kits and where to buy?

Any help is appreciated.

thanks
