Thanks for the replies. I just maidened the plane at Whittier Narrows. It was very gusty but I decided to brave the weather.
At first it was a very wild ride, with the plane really feeling the effects of the strong winds. It really was an adventure to keep the plane flying level, but I landed in one piece after the 3 minutes that were set on the timer.
With that wind, no stunts were attempted.
I think I must use a smaller spacer in the Renger handle to tone down the sensitivity.
The leadouts are where the plans state, so is the CG.
