Hi guys , I just finished my new ninja and test flew it the other week. I set it up the ailerons and C.G. as per instructions ,it flew fast and straight once trimmed out . Good inverted flight and tight turns, the only problem I do have is it will not do a clean loop ,it wants to roll over . Almost like a partial barrel roll ,I'm thinking I may have too much elevator travel. Any ideas?? otherwise the Ninja flys nice and it is predictable . Thanks Jim
