One thing I noticed is that I can't get the Bipe to harrier too well in AFP. It just won't stall, and when it does it drops too fast. It's hard to find a throttle setting that will keep it in a stable harrier. I'm not complaining though, I really like the plane. I just wondered if it's me or it's the plane. Another thing is that it does great upright flat spins but I can't do inverted that well. I've been spending a lot of time flying this one.

Your right Joe ... throttle response is the problem.

Do you have a throttle curve in your radio? If so use it! I do and it's perfect. Just set the throttle curve to your liking.

However inverted flat spins work perfect on my sims. Go high, point nose down sticks high and togeter, then slowly move the right stick from high left to high right. keep left stick up and left.
