Just got back from the field. I was pleasantly surprised. It was more lively than I expected. I took it up high and decided to play a bit. It will roll without falling out of the sky, and it will do a loop...if you get a running start. I hit the flaps and it slowed way down, no bad habits that I noticed. Came in for a nice slow landing, with full flaps. I'm looking foreward to flying this thing some more. It's ugly as all hell, but it is fun to fly...and since it's a gasser, it will be easy on the pocketbook too.
