Nuova faor SF-501 with carbon fiber Fram and upgraded servos to Savox 1258 titanium gear servos. Nuova does a pretty great job keeping everything top notch so thats all that was upgraded for the most part, aside from rec and battery.. willing to trade for giant top flight warbird, Cessna 310, or bonanza ARF. Would also trade for other brand of previous mentioned planes. Bike is set up with spektrum mini DSMX rec, $675 and the bike comes rtr, all you need is a spectrum transmitter. This bikes cost 1000 and thats before batts, rec, and titanium servos.
