4-Max
The Electric Flight Specialists

This motor is soooooo smooth, quiet and powerfull. It has enough power to go limitless verticle, not quite scale for a Harvard, but it's nice to have excess power  :o)

A 10 minute flight of gentle aerobatics and slow cruzing, low 'n' slow passes takes around 2,400mAh from the 3,300mAh packs.
