Unmounted one the motors from the dev board in the picture above, i was in a rush and bodge mounted it quickly, equally quickly i grabbed a airplane wooden prop and bodged that on the shaft. I was only going to get an idea of lift by holding the motor mount in my hand and wacking the speed up. I wanted to see how much power a plane prop could put out....
4-5 seconds at full blast and the prop came off!! Lucky enough it headed directly away from me and hit the wall. NO MORE BODGING!
Those little motors are seriously bad news if mistreated! Utter stupidity really, i guess i got complacent
