Auto conversion cost post

So George, fill us all in on how you took a 5 speed trans and used it
to transmit 500-600 pounds of thrust from the prop when in a car there
is no thrust loads on the output shaft at all??

I agree Peter, I also used the stock 5spd transmission as a psru, but did
use a lighter flywheel.

Over five years flying, almost 400 hours, I love it!

Sure Ben, Single deep groove bearings, and it is more like 300 lbs.
The stock output shaft is not used (too long).

George, the last I heard, you had some teething pains with that
transmission PSRU and got some busted gears. I have to assume that is
all cleared up, but what is a 'single deep groove bearing'?
