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.

Paul,

I've pretty much given up the notion of trying to make the engine work in a
vertical installation.  I hate belts and these things are tough.  There will
be no thrust or radial loads; all I need to do is get the power to the
transmission (in a helicopter).  I think the unit could be fairly light,
nowhere near the 70 to 100 lb the PRSU's do.  Do you know anyone who casts
magnesium?

There are some in LA but I don't have any names or addresses.
