Yeah foam-safe zap and accel. is the way to go... I honestly hate these Flatouts though! I have had several of them (Gifts usually) and they are VERY fragile- the hardware is innovative but I will take a Shockflyer and some packing tape WAY before I will mess with another flatout!

I have used extra CF to attempt to stiffen the airframe with some success but unless I catch it in a hover, it breaks somewhere, EVERY time I touch the ground--- And my landings are usually very soft-

I personally am going to move up to the next size/stiffness and try that--- Foamie Factory Yak maybe--?

Cheers!
