Testing speed controllers & motors.

[curt53]

Hi, does anyone have method for testing out speed controllers & motors. I have a spare controller & motor with the heli a bought & want to see if they really are spares not just knackered bits put in the box with the heli.when I wire them up the motor doesn't respond & the controller gets quite hot.
they are off a T rex 450, Align RCE-BL25G controller & Align brushless 430L outrunner motor. any advice welcome

The motor could be jammed, the magnets have a nasty habit of attracting little nuts and bolts inside them if your not careful. Its worth checking nothing has got lodged in there that would be a possible reason why it wouldnt run, also it would be pulling lots of amps if it were stalled and that would certainly cause a hot esc. Worth a quick look.

hi Oli, I did check for that first & did find a small screw in the motor but it wasn't causing it to lock,the motor does turn free but still not responding to the radio input. I'm not sure if it's the motor or the speed controller.
