This is my Hobby King X-4 FPV quadcopter that I, rebuilt using the arms off of my HK Predator Quad. The arms on the stock X-4 FPV are made of fiberglass and are very weak, problem solved !! my set up is as follows 12" carbon fiber props, Afro 30 amp esc, multistar 490kv motors, multistar 4S 6600mAh battery, led strobe lights, T-rex 600 landing gear, Naza Lite flight control, transmitter is a Turnigy i10 and a iA10 10ch 2.4G AFHDS 2A Telemetry receiver. I got 12 minutes flight time out of this setup motors and esc all run cool. Please comment and let me know what you think!! Thanks For Watching
