Hi Paul,

Been lurking on the list here for awhile, trying

to learn as much about

the rotary as I can.

I recently heard about a guy in FL who is

selling a conversion manual to

make an '81 Mazda tranny into a PSRU, with a

2.21:1 ratio.  He's been using

one on a modified e-racer for several hundred hrs

now.

Anybody have an opinion as to how reliable this

might be?

Thanks!

BD-4 eventually

I don't recommend it. A single spur gear is

marginal to take the engine

torque
and the small output shaft of a car transmission

is not up to the job of

coping with gyroscopic prop forces. That is a very

dangerous approach.

IMHO the risk is not worth the money saved.

Sounds like George Graham's setup.
I saw the plane at OSH several years ago and

talked to George at length

about his PSRU. He's obviously comfortable "flying

it".

The price is right, but is there any design margin

for the new application?

I would always wonder when it was going to

fail.....at high power loading on

take-off...it wouldn't be pretty.
Dave Stricker-

Thanks for the comments guys... guess I'll give this
one a bye!
