Hello:
I'm looking at a Q200 with a (1)rotor Mazda rotary. He says it has a

ROSS

2.85 PSRU. The (1) rotor was also built by ROSS years ago he said. What

is

the pro's and con's of the 2.85 ROSS drive? Is this OK for a (1) rotor

or is

2.19 PSRU better for it? Is ROSS, still in business?

The Ross 2.85:1 is a good way to go but you might have to add a sun
gear thrust bearing. I have no idea if Ross is still in business.

I STILL have a NEW 2.85 for sale (or a used one if you prefer).
