Fuselage in plastic material very resistant. Plenty of space inside, to install everything you want (fpv, telemetry accessories, autopilot, etc.). I installed the autopilot ZOHD Kopilot and it works very well. The recommended battery is a bit too light, the center of gravity would remain too moved back. I recommend at least a 3S 3,000 mah, with which you do about 20 minutes of flight.
