Ok, so i just downloaded a new video from the ms composit czech site of the ms230 bell hiller unit being used on a heli the same size as the blade and let me say. WOW! This guy was doing tic tocs 3 or 4 feet off the ground. this thing performs just like a larger size heli. i can't wait to get this unit, but i am having a hard time finding the unit as a whole piece. I think you have to order everything seperate. but i emailed ms composit usa site, and hopefully will here something soon. if anyone knows anything please drop me a line.
