RE: flat out turmoil.
With my battery placed ahead of the landing gear, and the CG at 3" aft of Leading Edge, the thing flew perfectly. Just a click of trim and off it went. Little rudder used in knife edge and coupling was minimal. Slight roll and pitch to canopy, didn't mix out cause it wasn't severe.
Very impressed with the way it flew. Hovered with a little over half throttle.
Set up is with as much throw on the control surfaces as I can get. Dual rates have about 50% on low and 100% on high. Expo is set to 50% on high rates only for all 3, rudder, elev, and aileron.
Lookin forward to more practice and stick time.
