Fat Albert had a cardiac arrest inflight....I took off and it seemed sluggish (more than usual). I attributed it to smaller mAh cells I had swapped out to save weight. RPM was down about 400 on ground tests but not a real big deal. I trimmed the elevator on one pass and on the next pass it was noticeably slowing down. I took action to land but as I was in a right turn to head on down-wind final I saw black smoke coming from the left side of the plane. Just like that the motors appeared to quit and I didn't have it anymore. It kept rolling and spun in from about 75ft. When I aproached the plane in the field it had a burnt smell and I sniffed out one of the motors on the left wing. Upon inspection at the field the commutator was pretty bad so since it was in series with another motor it dragged the system down. I am checking to see if the esc fried and if it nuked the BEC.
I looked at the airframe last night quickly and need more time to determine if I can rebuild. I would need to build a new nose but the wings look ok and the tail is, of course, perfect
