Ice Lite 100 4 red flashes

This just started after maybe 10 flights. I can power up the motor. When I go full throttle, the motor stops abruptly. At this point I see a series of 4 red LED flashes. I don't see anything burned. But I have not pulled the motor yet. I hate working in those tiny spaces.
Thanks
Mum

4 flashed is prop strike detect.
In your case it indicates a motor problem or motor wiring problem.
1. Bad solder joint between motor and ESC. If the motor came with pre-installed connectors that’s probably it. I have had that problem in quite a few motors. Now I take the connectors off all new motors and resolder them on myself.
2. Bad motor bearings
3. Loose prop or prop drive
4. Bad solder joint internal to motor
5. Shorted windings. Sometimes the motor is not would correctly and a wire touches the magnets. After a few flights the insulation is worn off and it shorts out when you run it up

Also if it’s a small motor some of those cheap small connectors are just no good. Soldering the motor wires direct to the ESC solves that problem.

Thanks guys. I found a bad solder connection. No time to fix so far unfortunately. But I'm sure that was the issue
