      Dear Sir;
   We here in Harrison, Arkansas have been experimenting with the

Mazda rotarys.

We have three eng. on tests stands. One has a gear drive from the

Mazda xmission

and one witha belt drive(both reduction units made locally) and

one with a chain

drive. Would really appreciate receiving your newsletter.
                 Thanks, Max Calkin

Beware that Mazda transmission. The lower gears won't hold up under
continuos
high HP needed in an aircraft application nor is the
output shaft anywhere near large enough to take prop gyro bending
loads. It could be bad for your health if your engine sheds a prop.

The best bet for a PSRU that is the lightest and the one we have
the vast majority of hours on is the Ford based C6/E4OD auto
transmission planetary.
Tracy Crook Real World Solutions makes the best PSRU on the market
using these gear sets IMHO.
