DeJa Vu Flutter?
I got an old Deja Vu with about 60 flights on it. It is a 165 mph fun fly airplane with a nelson .40. The problem; on the last two flights it began making a fluttering sound during aileron application with subsequent gentle elevator pull. During straight and level there is no flutter. The ailerons are gap sealed but the rudder and elev are not. All of the flight controls and likages are tight. Any suggestions. Thanks

4721 on both elev and ail which I think are 119 oz each. 3421 on the rudder. The ail servo linkage is hooked to the middle hole on the servo arm, should I move it to the inboard most servo hole?

I'm not familiar with the 4721, but at that much torque that should be plenty. The 3421 is a great servo, so thats not an issue either. I would suggest using the innermost hole on the servo arm and if you have control horns on the rudder / elevator I would use the hole furthest from the surface. Try to use 100% of your servo movement if possible.
