Learning the basic concepts. Yet to use a receiver and remote. Using a 3.7 v coreless motor, lipo battery and thermocol for the frame.
I figured out how to connect the motors so that diagonally opposite motors have same direction rotation and adjacent motors have opposite rotation. Also learnt how to arrange the propellers. I learnt that L goes for CW and R for CCW. Main thing is if arranged properly it will push air down.
In first attempt the frame was bulky and probably blocking the wind from being pushed down. Also it was bit heavier. It was sliding on the floor - almost lifting.
In second attempt it does visibly rise up and float in the air. Keeping it tied down by some threads on four sides.
However it flips over if not tied down.
I don't think flip over is due to motor or propellor arrangement. Studied that aspect I think adequately.
Will it not flip over if I use a receiver and remote?
Is it flipping over because the speed to the motors is full and not controlled? Will a receiver detect and adjust speed of each motor?
Will it be better if I weigh down the drone somewhat using enough light weights?
What frame is recommended for a 3.7 v coreless motor with 4.5 mm propellers?
