I have bought an A2212 1000Kv brushless motor and a 30A ESC. I power this setup with a 7.4v 2s 30c 800mah LiPo battery. For the signal, I am using a DIY Arduino receiver and transmitter. When I test the motor with a test code(linked below) and without the propeller(10x4.5) it runs fine. But with the propeller on it, it makes a booting sound and then, beeeeep beep, beeeep beep beep. These beeps are not constant rapid beeps and it just keeps looping these sounds. Sometimes if I'm lucky, the motor will start and then after a second it shuts off and reboots and does not work again. *what I have found is that the motor cuts of at around 60% throttle.

I have spares of these two items and I have the same problem with them. These motors are new and I have personally never seen them run with propellers, only without propellers.

How do I fix my motor?

Assuming stable power to the ESC, it's probably an issue with comms between the FC and the ESC. Sounds like they're rebooting. Check protocol, wiring, etc.
