I put about 100 hours on my ITV BIlly. Its a great intermediate wing. Easy launches and landings. It doesnt hang back on launch and has a nice flare. I flew mine mostly with the trims 1/4 of the way out for everything except for flying straight line long distance where I would trim all the way out. Trims out it really picks up a lot of speed and is very stable no tendency to oscillate like slalom wings. Speed bar doesnt do much for the wing, maybe increase 2mph. Its not the most efficient when trimmed out, my ultimate 130cc motor needed almost full power to maintain altitude at full speed. Its also good for learning wing overs and basic steep turns but dont expect to be doing barrel rolls or really huge wing overs, it just doesnt carry energy that well and has lots of stability built in.
