Paul,

Do you know of anyone using a Hy-Vo chain for power transmission with the
Mazda?

Steve Brazil

I don't think anybody is currently flying with one.
I know people have belt HiVo chain PSRU's but they tend to be heavy.
This one, designed for a V8, weighs around 100 pounds as I recall.
It is hear at SZP.

Paul,
The biggest problem with the Hi-Vo chain is the geometry works like a
gear,
the teeth are involutes, so the sprockets must be steel. The chain
requires
an oil bath or spray bars which makes everything heavy. It is a strong
and reliable
system though.

If you go to legendaryaircraft.com you'll see images of the Hy-Vo PSRU
used on the P-51 replica.
