Light planes fly and 3D better than heavy. "Build to fly, not to crash".
I cut holes everywhere, didnt break it. The extreem has a thick wing, you can land at 0 mph in anything above a light breeze.
(first and only plane I have done a vertical landing with)
Too late for cutting out the ribs, but could still do the fuz. I also should have mentioned, but I forgot, to put aerodynamic balances on the elevator and rudder, again like the Lite.[&:]
