Great maiden!! I've found that throttle control is everything with high alphaing this plane, once you get that down the plane really starts showing its full capabilities
For example when I usually high alpha I'll pull the elevator back to one spot and control the angle of attack using the throttle, I'll also make sure I never max out the elevator when I high alpha so I have a little extra in case I need it...
A cool thing for you to try is try going up 20-30 ft. and then try and high alpha to the ground. The goal is to try get it falling straight down while in a high alpha. I've gotten it almost vertical. I want to see if you can figure it out, if not I tell you what to do...Oh, and doing it into lots of wind is cheating
