Cheerson CX-20 Drone Altitude Hold Test Flight
Altitude hold is a great feature of this quadcopter that aids in distant flying. It helps to discern if the quadcopter is approaching (moving higher above the horizon) or moving away (moving closer to the horizon). It also eases flying in that the quadcopter’s throttle control is automatic to maintain a steady altitude. Find the $224 CX-20 here http://shrsl.com/?~8owx
