Default High Power to Weight Motor

Hey guys, for an engineering project we are looking for a motor with a very high power to weight ratio. We are looking for very high rpms, in the order of 65000 rpm. The power to weight ratio should be above 20 kW/kg. Very new models are welcome, preferably from the last two years. The motor has to run at peak power for approximately 10 seconds. The operating voltage is still open, we are free to choose our batteries as well as cooling. The high RPM is not necessary, but the high power to weight ratio is (Above 20kW/kg).

Any suggestion is welcome and the budget is not an issue Name:  wink.gif

I'm not aware of any RC engine that turns 65k RPM.
No one can give you a useful answer with the information provided. You haven't told us anything about the overall power needed, intended purpose, etc.
Of course, we probably shouldn't be doing your homework for you. The various RC motor manufacturers publish their specs. It's easy enough to read them.

Don't pager motors spin up that fast w/o their offset weight?
