Ran 4 of these on a quad powered by a 2 cell lipo. Worked well with big props.

Nice. What weight is your quad and how long was your flight time?

I don't think we actually weighed it; It was two aluminum bars put together for an X quad with an APM flight controller. I was surprised to see such large motors do a nice job of driving a quad. target=_blank>quad_mtdew

Well impressed with this motor - my daughter had a Century Riot - Rubbish kit no guts at all I put this motor in having made a change to the cowling added a hobby king controller and it goes brilliantly - it is a perfect 40 size motor with grunt and at this price a bargain. I use 4 cells with this and it is a perfect match - 3000 or 3300 lipo's. the great thing about this motor is the 5mm shaft - no chance of bending this in a hurry.

800 watts on 4s no problem, but bushings wear fairly quickly, still usable but slight vibrations due to wear.

Heres the thing, i am running these on a 4s with a 11" slow fly prop on an octo, these motors heat up big time, hot enough that some of high heat glue from my hot glue gun melted. And i was at 50pcnt throttle most of the time, not goot at all. Thos cheap bell type brushless outrunners that are blue and say 3s max, i rand those on a 4s with 12" props, they get slightly warm, are half the weight, half the size and cheaper, they also give the same thrust pretty much, this donkey motors are just rubbish
