I installed a new IO-360M1B and MT 3 blade from Vans on my -7, with the new 59B blades. I am VERY pleased with this combination after 100 hours. Takeoff and climb performance is outstanding, and I am dead even with my hanger partners 180/CS Hartzel RV8 in climb and cruise.The MT was incredibly smooth BEFORE I had it balanced. Weight and balance numbers came in right where I had hoped. A little pricier than the Hartzel, but prop includes a beautiful painted & installed spinner assembly. Literally bolt the prop on and you're done. Have flown in rain, soft fields and frozen lakes with no blade erosion whatsoever. Also using the MT governor supplied with Vans FWF kit, dead on at 2700 rpm/no adjustment was required. 12 week lead time on delivery from Germany and the prop is shipped to a local dealer for assembly and delivery.

Default Very happy with mine

In my case I can out climb but have lower top speed than other RV7 aircraft I have flown with. This is in line with much of what I read on this forum as well.
We are taking a knot possibly two at low alt so the difference is rather small. I also just like the look of a 3 blade

If anything, the three items I would suggest you consider are:
1) I feel the 3 blade composite reduces vibration a bit over metal 2 blade
2) The light weight of the prop and modern starters shifts the CG weight back enough where you will hit aft CG limits before gross weight unless dealt with during the build.
3) It will be harder to remove the cowl for service

Default MT Prop

I am currently building an RV7A with the angle valve IO-360. I am considering a Sam James Cowl and Ram Air kit. Does anyone know if the MT 3 blade prop would require an extended hub for this configuration?

Thanks much

Just tell MT your engine, induction type and cowling and they will send you the correct spinner and extended hub.
That?s what they did for my combination:
Lyc-IO360-M1B, horizontal, Sam James long cowl.
You can contact Eric Greindl. Eric.greindl@REMOVETHISmt-propeller.com

You might give McFarlane Aviation a call. They are the new master distributor of MT props in the U.S. I had the good fortune to speak with Dave McFarlane himself at length regarding the MT prop. Mr. McFarlane flies an MT on his personal aircraft as well. His knowledge and personal experience gave me loads of reasons to go with MT, so I did. The reasons extend to go MT go far beyond flight performance.

My guess is that we'll see him advertising on this site one of these days.
