New Props?

Capt Tom, Flyin' Finn - In the process of replacing 5 blade Rolla propellors working with Precision Propellor.

Looking for any feedback from those that have been down this road. Any help is appreciated.Attachment 72930

My experience with props has been that if you're still running around on 40 year old dynajets or whatever, then there's a decent shot that going with one the new high-skew designs with more blades will produce a noticeable performance and fuel burn improvement (usually at the cost of a knot or so of top end because they're more efficient at producing thrust but slighter higher drag). But if you already have Rolla's on there then somebody already did that and you aren't likely to see a whole lot of improvement.

Rollas are among the best, not sure what you re trying to do.

I'm happy with the Rolla propellors however they sustained damage. Replacement Rolla propellors are no longer a viable option and was wondering if anyone else had replaced their propellors with something other than the Rollas. It looks like Veem will be the way to go although that its being spec'd but with a different number of blades and pitch, etc than I am currently running.

Veems are excellent too

I bought Veem propellers a few years ago, from General in Bradenton. They have been fine.
