Well... bad choice of the motor I guess. I use 2 brushless motors from a quadroter.

The motor is getting slow after cutting grass for seconds. If I have it spin freely it runs OK as long as it should. Any ideas??

(I use 30C 3S lipo 5AH, shouldn't be power problem. )

Why not use a real one ?

Look for a used cordless weed-whip on craigslist/ebay/local and just hack it up as an attachment/accessory…

BTW - very nice platform hardmouse
