All motors on the quadcopter are identical, so we can analyze a single one without loss of generality. As a result, the quadcopter will move forwards. Incorrect Motor Order. The faster the rotors spin, the greater the lift, and vice-versa. Found inside – Page 79When both motors spin at the same speed, they produce the same amount of thrust. ... we've got ourselves the rotorbase of a True-X quadcopter. At 49% . The motors receive power from the speed controllers and turn the propellers. The motor test will then proceed in a clockwise rotation. Common propellers have specific rotating direction, It's clockwise and counters clockwise. it should be set to a minimal value that is enough to let the motors spin smoothly - they should never stop or desync in airmode. after they get to a larger size they spin 40k rpm . Although much more expensive to build due to the fact that you have to buy 2 extra ESC's, Motors and cables, these are a little safer than quadcopters - if one motor fails in Mid-Aid, then you loose the yaw (turning left and right), but you can still land it - Just about! Everything is fine except the one problem which involves the motors not spinning at the same time via different throttle rates. I got a problem. The ESCs then use this information received from the flight controller to control motor . The ESC takes the signal from the flight controller and power from the battery. Also, the 'MOT_SPIN_ARM' parameter in mission planner is set to zero so that the motors stop as soon as throttle stick drops to zero. In the case of X8, it will spin the top front-right motor first, then the bottom front-right, and proceed around with . When I would go to launch the drone, it would lift to the side really fast causing it to crash all the time. I had issues with my cheap quadcopter as when it would run while still in launch position, the motors were off sync as you could hear one side of the props speed up and then the other side would speed up, going back and forth.
