Aileron flutter. The wings came off. The parachute worked. I thing he still has mementos of the glider under his bed. do not archive ________________________________ Message 2 _____________________________________ Time: 01:02:35 PM PST US Subject: Rocket-List: Re: Fin attach From: "David.vonLinsowe" --> Rocket-List message posted by: "David.vonLinsowe" Thanks Vince. I wonder why Van thought he had to go to the counter balanced rudder? Having been in R/C for a long time and seeing flutter first hand, I know I don't want to experience it while my butt is in the airplane. On a side note, the G-202 prototype had a case of aileron flutter. They were lucky, from what I've heard it was over with a bang before the pilot knew what happened. Blew the aileron off without damaging much else and he was able to safely land the airplane... Dave http://www.usi.edu/science/chemistry/vfrazier/Everything%20else.htm scroll about one third of the way down for a pic of how I changed my VS attach to resemble the F-1 stuff. I don't have a rudder counter balance. Is any of this necessary? According to several HR drivers I've talked to.... No. It's your choice then, isn't it? Vince
