I just ordered my 12 holer from Sabre along with an 1 3/8" crush plate. CG issues are resolved. With the extra 2 1/2" forward and the crush plate I'll even be better off than bolting one of those Sensenich props up front.

Darrell,
Did you have to specifically ask for this?? I just ordered my finishing kit (RV8A) about a month ago and told them I would be installing an O360-A1A. I also told them to leave out the spinner. I plan on a Catto 3 blade prop and I'm starting to worry about an aft CG. So a longer engine mount might be just what I need as well.

The mount is for my HP-320 custom built engine. The difference is 320 vs 360. The RV7 engine mount forward is different for this set up by Van's design.

By the way... it can still work for you. You would buy the mount and cowl for this set-up, but would need to retro the snorkel for a 360.

Hi Guys
It has been 18 hrs since I re-torqued my catto prop. How many hrs. before re-torqueing?

I've been running mine just over 3 years now and I check the torque at each oil change. I have not found it to vary.

Dave,

I ordered my spacer and crush plate from Saber. Sam is a wonder guy to deal with! We did the calculations for my set-up and he special orderd the material for my crush plate. It should be delivered in the next week or so.

Sabre is great, I was wondering if anyone has a source for a weight (Steel or lead) that can counterbalence Catto? Putting on a Whiteman W8 Tailwind, and it's getting an Aft CG problem.

Try a Landoll ring. He has just a plain jane ring, which I have, or a harmonic dampener. With the smoothness of the Catto, I did not opt for the harmonic dampener.

The Landoll ring that I have puts more weight out front as well as gives more enertia to the otherwise very light prop for better idle.

Regards,

Searching, how do I get ahold of Mark? Sorry about the thread hijack.
