Hi ALl,

My first post - hope I am not breaking any rules.

I have a vey basic drone which I picked up to get to grips with piloting a drone, to keep me and the kids entertained.

After a collision with a an object in my garden the drone will no longer take off (the collision was no worse than any other it has had whilst I have been getting to grips). Now when it tries to take-off it seems that lift is lacking on the back left rotor and instead the drone start to rotate/pivot on that corner.

I've tried re-calibration, I've inspected the rotors and changed them, and tried also swapping the the rotors with the corresponding front right rotors. On one occasion it appeared to be fixed, rose about a meter then set back down on the ground.

Any ideas what might be the issue, when the rotors are spinning the problematic ones do not appear to be any slower or different to the other 3.

Thanks in advance.
 
Just got around to trying this fix, I took the drone apart and although the motors fit and look the same the cog is slightly bigger so it doesn't turn the cog of the blades.
 
Ah I didn't think of that, so I managed to remove the original cog but seems that the drive shaft on new motor is larger in diameter than the newer motor. As a result the old cog won't push on to the shaft.

The new cog (left) has 10 teeth, the old (right) has 8 - as can be seen I've actually damaged it when removing.

I might be just as well to try and source a same brand drone for parts otherwise I might be forever chasing my tale :)

These small brass cogs get used on the motors of RC Helicopters but your shaft may be to small but is worth a look they come in different numbers of teeth
 
I've managed to source what I think is the correct motors from Alliexpress, I had no idea that the cogs came in pretty much every variation type. I've found an 8 teeth drive so hopefully this will do the job. Will report once I've fitted them!
 
Finally managed to fit the new motor - the drone still will not take off, it tries to pivot on the back right motor which was the original problem. I guess the motor was not damaged after all.

Not sure where to go with this - I cannot see any damage so I'm kind of beaten. One for the trash?
 
Sorry to hear your still having problems , with coreless motors you will not see a sign of damage , but you see lack of lift from the motor
toy drones can be a nightmare to fix most put them in the bin due to the problems with coreless motors can you move this motor to another arm to test if it's motor or another problem
 
just realised that the new motors are fractionally smaller and lighter I guess, trying to fit another replacement on the other rear corner. If my assumption is correct I guess the drone will tilt to the rear and I may have to change all 4 motors.
 
Yes that's what I used to do , I know you may not want to hear this but may be look at a hobby grade drone with brushless motors
 
I was wrong, added a new motor so that both rear have new motors and the same. Tried switching the corresponding props and guards but to no avail. More than anything it is bugging the hell out of me!
 
Ok are both motors turning the right way ( left is anti clockwise right is clockwise ) looking down on quad with back towards you , if right now check props are the right ones on the right motors
 
Props are labelled A (front left and rear right) B (front right and rear left) - two props on each motor.

A props spin CW, B props CCW.

I'm certain this is correct?
