Our S-1S is a bit on the portly side - 870#. We have an O-360 A4A, PS5 and a Sensenich 76-56. We want to go with a Catto for both the weight savings and lightened flange issues.

We are looking at a used Catto 70-62 three blade with Vortillons. It was too much pitch for the seller’s Acrosport with the same engine we have. However we are 150 lb lighter and cleaner than his AS.

My gut says this might be too much pitch for us as well. Does anyone have experience with a similarly pitched 3B Catto on an S1S? Thoughts? Opinions?

Thanks for your help here,

Bruce
