You could 3D the plane with 190 watts/pound. Thats more than enough power.

As to whether or not the motor would actually survive at its rated power - I doubt it.

The specs on the Hobby City stuff are usually wishful thinking at best and outright inventions at worst.

I have yet to see any of those motors made with metal parts that could survive at anywhere close to those power levels. The last one I tested was rated to 2000 watts and began to fail before I reached 1000 watts and was grossly unsafe. The aluminum parts were not tempered at all. No way the motor and especially the prop adaptor could handle the stresses.

Be careful and good luck!

Thanks,
you know I was thinking the same thing on a motor with that much power,
I may have to look at another motor may the Hacker A-100 0r A-150 didn't want to shell out almost $1,000.00

The big Hackers are actually a pretty good deal as far as watts/$$ go and they will actually do the dance without killing you or an inocent bystander by shedding a 24" prop at hi power levels.

Unfortunately, you are also going to have to shell out for a name brand controller if you want to play in that power range.

The Hobby City hi voltage controllers are even worse than their normal stuff. Their HV controllers cannot even come close to performing at thier full rated values.

If the controller says it can do 12S at 100 amps you'll be very lucky if it survives on 10S at 75 amps in short bursts - less than 1/2 the power you want.

Your going to have to get a Kontronic Power Jazz 63 controller or special order one of the new Castle SHV controllers - if they are making them yet.

Jetti is suposed to have a new 14S or 15S controller out as well but I dont know anything about it or if you can even get one yet.
