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?

Never flown one, but have seen tests recommending AXI 2808/24. Then you can compare the AXI and your Phasor...

Thanks for the help. i've built the plane and decided to use two 3 cell 2000 mah packs in parallel. i'm waiting for the weather to calm. it's to windy, 35 to 40 mph gusts. i'll let you know how it turns out later.
