Zenoah G-45 Recommended Props
 
Hey guys, I am not having much luck on searches so here is my post. What are the best props for a Zenoah G-45? I am also particularly looking for a 3-blade prop. Zenaoh recommends a 20x10 2-blade, what would be the best size 3-blade (18x10)??

Any help would be greatly appreciated including where to find such a 3-blade prop. Also, this is not for 3D flying, rather looks and ground clearance.

Thanks!

All in what type plane and what type flying you will be doing, As a rule I have always heard just to drop one inch for 3 blade,

The plane is a 1/4 scale Super Decathlon. I am actually using this plane as a winter flyer to break in 2 G-45's I plan on putting on my B-25. I would like to run 3 blade on the B-25 and could use the ground clearance on the Decathlon.

Thanks

I like the 19 x 10, 3 bladers from Menz on mine (1/5th scale FW 190).

F4you, do you know what RPM's you are getting with your 19x10? Also, where are you purchasing this prop from? I cannot seem to find a source.

Thanks

As I recall it was mid 6,000's. I get props from SisT in Germany. I'd think Aircraft International would either have them or could get them for you.

On a tug plane, I had used a menz19x10 with a krumscheid 1050, and a carb truppet. It was the best compromise between take distance, speed to compensate pilot error and traction (up to 6meters glider and 20Kg)

The same engine is now on a dimona 1/3 scale 5.6m, 15Kg. Home made, simple exaus system (fully integrated in the big cowl), carb truppet. I use a menz20x8. It can tug, I have test up to 8Kg/5meters, it can track more, but I have never had the glider on the field...
