Oh, man!! It's cheap! I thought I'd never see a motor of this size for a very good price. Too bad I gotta wait another month for it. If it swings a 8x6SF prop, I believe it won't have any problems with a 9x3.8SF. I bet it can also take more than the max recommended current, just like its big brother the 300 does.

??? 8x6 sounds a bit much for a 2200kV 50W motor IMHO more like an 8x4 maybe. Either that or the motor is 200% efficient

To even get 6000RPM (50% slip) on that prop takes 50W at 80%. It will also be interesting to see if the weight is without wire and without mount?

Even on an 8x4 at 8000 RPM you need over 80% effeciency at 50W in.

I don't think the posted weight counts in wires and maybe not even the mount.
If it can swing a 8x3.8SF, I'll be more than happy.

probably incorrect term by me (to many beers )but 2200kv x say 6V = 13200 RPM.

What I was getting at is that even at 6000 RPM (motors drop some RPM under load) the motor figures on Horizons site are rubberey.

Well, I don't understand much about motor theory. All I know is if it is able to pull my plane the way I need it to and, mostly important, doesn't cost me much, I'll take it.

I've been running a Park 300 and love it. $15 less than the 2204 (I actualy paid a couple less than retail for mine), and it's a lot of bang for the buck. It may not be much, and maybe the AXI's well worth it the extra money, but $15 in my current budget could mean an extra battery pack or something else.

As soon as I get one, I'll have some numbers (not thrust #s, thou). If they've advertised the numbers as accurate as they've done with the Park 300, then it will be spot on.

I miss the thrust vs current data to see if my poor etecs 450 can handle it

50 watts on 7 volts is about 7 amps max. I've hit my etecs harder than that. Just burst responsibly.
