Savage XL outrunner conversion

WTF?!

Well, a few minutes ago i completed the reassembly of the savage and i did a test drive.

But this thing has no power. It can barely get speed.

If i let the wheels spin freely it balloons that much.

I think there was something wrong with the scriptasylum calculation.
I had to stop the test because the motor got almost too hot.

Any suggestions for improvement?
