Quadrocopter on brushed motors, assembled on the basis of a quadrocopter (jjrc h 31).The essence of the project was to transfer the flight controller board to a new case, simplify the design and add an FPV camera to the device.Are used:1) carbon beams - 2 pcs.2) flight controller from jjrc h 31 quadcopter3) body made of abs plastic.4) 4 large gears with 54 teeth5) 4 gears per motor shaft (model worked out)6) 4 brush motors for watches. (their rotational speed is sufficient for the basic blades of a jjrc h 31 quadrocopter)7) You can experiment with the battery. I used a base 400mAh 3.7v 30s battery. Flight time is 6 minutes.
