580 watts 36.2 amps @ 16 volts.
The data on the motor suggests that it is a 500kv motor that would amount to about 8000 rpm.

Note that the KV ratings for motors are all quoted for "no load", so as soon as you stick a prop on, the rpm figure drops dramatically. It's probably down around 6,000 rpm depending upon your propeller.

I guess you've had a trawl through RCGroups? - are others seeing the same sorts of numbers?

Good luck with it! I've just taken delivery of a Dynam Trojan and probably going to remove the stock motor and put an SK 3542-1000 in that before the first flight, based on the 80 pages of reports on RCGroups.
