RE: .25 size nitro profile?
be careful on buying the fun p51 mustang profile from tower hobbies. i built one and it flew a few times and than started a viabration i never got out. it maybe ok with your motor, but i had a a super tigre 51 in it. very fast i will say and a nice kit. it sounded so loud with the vibe in the wings it was very noticeable. it affected the way the engine ran, believe it or not. the profile fuse is weak. even though it is lamanated it's still has no sides or top or bottom ,like a built up fuse. it flexes very bad in the middle, right behind the wing. i even reinforced it there to no avail. keep the power to a .32 and you should be ok. it is however a nice kit for the price....................RON
