Guys,
I've used both the 250 and 210. I prefer the 250, if it could take the abuse I put it thru. Starting with 10s packs and swinging a 18/10E APC.
If you can, run the motor at fast idle after landing for a minute. Do not turn it off when you clear the runway!! I think the thermal soak killed my motors.
If Scorpion can resolve the magnet-retainer ring bonding issue this would be the best value out there.

I've since installed an AXI with great results.
