Paul, Unfortunately I will be unable to attend Ausfly, if anyone gets
the Rotary bug from you please let them know we have a couple
available with PSRU. One has Tracy's unit and the other has the Ross
version with the appropriate thrust bearing mods. Perhaps you could
give them my email address as we will be travelling all of October
with some email access. Thanks

John Evans

What is the gear ratio of those PSRU's John? Are you in the US or Oz?
Shipping cost you know :-)

My Tracy Crook PSRU has a ratio of 2.85:1, it is already set up on a turbo 12A, but I have never run it. I don't know the ratio of the Ross. We had it set up in a gyro with a 4 blade Warp drive prop. In normal aircraft practice the throttle was designed to go to full bore if the linkage failed. I do not recommend this in a gyro as the linkage did fail, the acceleration was such that I was unable to shut it down before breaking 5 strands of a high tensile barbed wire fence.
Linkage failure of a gyro must reduce power to idle, full throttle can be dangerous!
I am in Oz, I live near Newcastle so freight would be no problem on the east coast.

John we may visit Russ McFarland in Newcastle on the way back.
