Motor won't spin cog

Hey there, got an electromax eye drone. Bought two since the first one broke so I guess I have spare parts? Anyone have an idea to fix or replace motors?
The motor I have works but it's REALLY rough to spin the cog. The cog at first felt clanky and sometimes worked. I dismounted the cog from the motor and now even if I force it, I cannot get the cog spin easily.
Any suggestions to unscrew the problem I did?
Btw, what caused one of the motors was that it hit a thin branch tree and landed upside down, if that helps any.

Those look like little brushed motors, did you kill the throttle as soon as you crashed? If not it's very easy to burn them up. You can take that same motor out of your other one and solder it in place of the defective one, just Make sure it's the same motor, if not it may pick the wrong one and it will spin the wrong way.

I did cut the throttle before crashing. The motor DOES spin the cog. I heard the clanking noise from the cog so I removed the motor and fiddled with it. Sprayed WD-40.
Now the cog is almost impossible to spin even when I force it with my bear hands.

Either way, motor is junk, replace it.
 
Also, I DO have another drone that has one motor not spinning that is the exact same model. Would it be possible for me to disconnect it and mount it on the other drone?

Yeah, like I said in my first post just make sure that you replace it with the same motor from your other one. You may have to solder im not sure if there will be connectors or not

Never use that stuff on plastic.

It is likely that it won't hurt the plastic but WD-40 is NOT a lube, it is a rust solvent, it does not lubricate any better.


If you wish to lubricate take a tiny bit of dry lube like graphite, or silicone, or something like a grease (white lithium grease and ect.).

It's also the best substance known to man for removing icky kids' finger prints from stainless steel kitchen appliances (and makes the kitchen smell 'more manly'!), but I ~may~ be digressing somewhat… let me know if I'm not helping! ;)
 
So white lithium should allow the cogs to spin more easily? Because I see absolutely no debris or wear on those parts and it's very difficult to get them to spin.

Only if they need lubrication, and not the thicker type, a lower weight. I'd completely take apart the drive system and try to isolate the problem.
 
Here's how I would trouble shoot this:
1) Check for any kind of debris in the gears. (Sand aka: silicon granules, can be stuck in the recess of the gear. Since it's more or less translucent, you may not be able to see it just peeking into the motor/gear housing)
2) Remove prop and motor assembly. Spin motor to test for rotation smoothness
3) Check main gear (cog) and shaft to prop. Does it spin freely once the motor is removed?
4) Check motor with power (ALL props removed) from transmitter signal. Does the bad motor spin freely or does it labor to rotate?
5) Check bushings or bearings for wear or debris
One of these should get you closer to the problem.

Good luck.
 
Still waiting on the soldering equipment since my girlfriend and I are getting an apartment soon so this toy model will have to wait.
In other news, I finally bought a 250 series drone. :D

Hahaha, sounds like you might get to do some fast-n-low flying here soon.
