has anyone flown a protech onyx 15 pattern plane? and what did they think of it? i'm building one now and trying to get an overall idea on what to power the plane with and the performance of servos. i've got a jeti phasor 15/3 motor and a 40 amp jeti speed control. the batteries i planned on using are three cell 2000 mh lipo batts. i'm not sure if that not enough batt for a ten to fifteen min flite. any ideas?
