RE: Alpha 60 RTF
imora-
Congrats! I told you they fly nice. As you start to get more comfortable and try aerobatics, one piece of advice. At the recommended control throws, it is difficult to do a roll with ailerons only. Add some rudder input as well and it does a nice barrel roll. Also, despite what others may tell you, the Alpha will fly inverted.
Regarding the vertical stabilizer, is yours not also bolted on? Mine is, although I my add some epoxy as well.
