Review on Uxcell 16Kg Cm Self Locking Encoder Reduction by Charles Lewellen

I did some initial testing and programming of the engine and it ran great under load. Probably only 30 mins. Then I built the mount and fuselage and hooked up the motor for testing. It worked for about 30 seconds (no loading) then I tried again (still no loading) and it stopped working. I checked the motor and now it has no continuity so I assume the coils are broken? I checked through Amazon and emailed the seller about the "guarantee" but no response. Maybe it was just an accident but no answer and no replacement = bad rating. If the seller did it right I would have updated this review.
