Mine I upgrated with 1100 kv brushless, 2S-3S (7 v for slow flight, 11v- for GOOD aerobatic! with trust ~ equal to weight!) 1500-2200 mAh lipoly is enough for 10-12 min of flight, wings covered by film gave much better aerodynamic and aerobatic. Best propeller for it: 9x4,7". See video with 808-camera on inetTVchannel
