In responce to the byrons cap 21 I think I must have one of the oldest ones going it has close to 100 hrs on the air frame.Plane has had Q-35,Q-40,US-41 and for the last three years has had a Q-52 and this thing is not for the faint of heart as it will high speed snap as well as slow speed snap.My plane is at 17 lbs and has been repaired a couple of times but can still catch me of guard if I don't pay attention to it.That said it is still lots of fun.
Thanks John
