Hello. We’re building a quadcopter for our project and we’re using a ardupilot apm2.8 and a flysky ia6 receiver and transmitter. We’re done setting up the flight controller but when we’re going to fly the copter, it does not fly, it just turn down. Can you help us solved the problem?
What do you mean by 'just turn down’
checked the motor rotation is correct direction for each arm?
checked the correct rotation propellor is fitted to each arm
checked the printing on the propellor is facing upwards as this affects prop lift?
