Can anyone tell me if there are cowling (or other ) issues if I initially
fit my RV7 cowling for a fixed pitch sensenich prop and spinner and later
upgrade to an MT? I suspect that the spinner and backing plate will make
for a difference in spacing from the cowling. I would want to build in
this difference so I don't have to modify the cowling later. Anybody know?

Hi Beven and All,
Normally, when you order a new MT Propeller, your existing spinner diameter
and cowl spacing is required.
MT Propeller then fabricates the spinner assembly on your propeller at the
factory to match your cowl installation. This propeller assembly is then
shipped as a custom fitted bolt on product.
Bottom line: Fit the cowl to what you need now, MT will match what you have
when you want to change.

You can always shim the engine mount away from the firewall if it comes to
that. Rosie recently did that after 2000+ hours -- switched from a
Sensenich fixed-pitch to a Hartzell constant-speed prop. The spinner back
edge contacted the cowl. He was gonna have to modify the cowling a bit
(build up on the inside and then chop/sand off the outside to increase
clearance) when somebody suggested he just offset the engine mount forward
with shims. He did that, bingo...clearance issue resolved. No need to chop
& repaint.
Not saying this will work in your case, but it's an option to keep in mind.
Best case scenario -- find somebody who will lend you their prop for a day
so you can fit it and see how much clearance you'll need. Then give it back
and fly with a mondo gap in there until you buy the real deal. Ugh.
