4 CH Russian Knight SU-27 Twin 64mm FLANKER 3D Aerobatic Radio Remote Control Electric Ducted Fan RC Fighter Jet RTF w/ Dual Brushless Ducted Fanstar rating 4RCSeptember 10, 2010The airplane is a little underpowered, but flew OK. One of the motors was bad on my plane which required a bit of work to get the fan unit out. The motor leads are soldered to the ESC leads. Each ESC is rated for 18 amps which gives you an idea how much power the motors need. One of the greatest assets is the way how this plane lands. Landing in the wind is a bit above walking speed roll out is about 10 feet. A decent fun airplane it fly.
