This was a 2 channel toy plane. I took out 2 brushed motors and install a brush less motor tower pro 2410-12, with 25 amp ESC and  4 servos 5 gram tower pro, and a new strong landing gear and one extra wing at the top... now this is flying very well with 2s lipo 1000 mah

same done by a friend of mine, converted an old brushed thrust vectoring glider to 3 ch Rc.

Still flies great

O yes, your model is 210, and mine 211..
