Thanks to all that responded to my recent exhaustive list of questions. I
had mentioned that I was interested in using the CAM500 redrive on an LS-1
V8 and someone asked about whether it had a provision for driving a governor
for a constant speed prop. I revisited their website
(http://www.aero-engines.bc.ca/cam500.htm) and re-confirmed that it does.
The only drawback is that it is expensive (about $11,500!). But I like the
fact that it's case is machined from 6061-T6 billet rather than cast, and I
like the idea of a helical gear drive versus belts or chains. I am
interested to hear back from the Marcotte redrive people that Bob P. put me
on to since that redrive is also supposed to be a helical gear system. It
sounds like it is a lot cheaper! I like the fact that helical gear redrive
systems have a history of reliable use in airplanes. Prop jets to be
specific. And they have to reduce about 13,000 rpm down to prop speeds! I
have no qualms about the reliability of a properly maintained V8 engine
conversion. What worries me is the reliability of the redrive. I wish
someone would design a redrive that would provide a "limp home" feature that
would allow the engine to continue to turn the prop somehow, even in the
face of a complete redrive failure: A lever in the cockpit that says,
"Redrive" or "Emergency Direct Drive".

Now if I could just stop worrying about that pesky "propellor not vibration
tested with my engine/redrive" issue...

Brent, after going to your website and following your links I realized I had
been to your other sites before.

For those who haven't go check out the carbon monoxide detector Brent has at
