Cheerson CX-20 Big Fly Shark ESC Calibration

Many people looking for cheaper alternatives to the DJI Phantoms have stumbled onto the Cheerson CX-20. This quadcopter for the most part looks very similar to the DJI Phantom and even includes the same motors as the Phantom 2. But what you may not have been aware of until after you purchase one is that there a 3 versions of this quadcopter and all 3 look exactly alike. You will have to take the top shell off of the quad to see exactly which of the 3 that you have and once you find out that it’s the Big Fly Shark version disappointment quickly sets in. There is very little help with this particular model but the forums for the Big FlyShark flight controller which this model comes with is the direction you want to be looking in. After spending days trying to fix my brand new quadcopter I got lucky and found a few youtube videos that got me up in the air and flying. Check out these videos and best of luck with your quadcoper.
