Heli-Max is hobbico, see here [link]http://www.hobbico.com/[/link]
if you jam the throttle stick to full throttle really fast
um, I didn't hit full throttle, more like 1/4 throttle, and I do have the ESC in governor mode (ultra soft start). The part is junk.
How many people have broken this part already? Respond to this message, thanks.
