Propeller Selection

[Bruce_L]

About to open a can of worms here.... What's your propeller choice?

I kindly ask you to limit answers to tractor propeller installations only, regardless of airframe or powerplant

1. Why choose that brand?
2. What size - diameter and pitch (please list your motor and displacement for clarity)
3. Blade count - 2 or 3
4. Material (carbon wood ???)
5. Vendor you like to use
6. Overall satisfaction (if flown with it already)- does it vibrate? does it climb good? etc...
7. Other comments - suggestions

I am leaving price out of the discussion, I want the best prop for my plane, not hunting a bargain here

I have read a lot and am still on the fence with 2 brands of carbon fiber 2-bladed props

I've used all 3 of the popular brands, Warp Drive, PowerFin and Tenn wood prop. The smoothest is wood. The strongest is Warp Drive, but heavier. I now days use the PowerFin 2 blade. The 'E' prop really impressed me the most, but it is a gamble getting the right pitch for max static RPM with a fixed pitch. I like the ground adjustable because you can tune it to your engine and needs such as speed or climb. Prop loading affects the EGT's a great amount. Too much pitch and low EGT's, too little pitch and you have high EGT's. And these conditions should not be adjusted by changing jets. Change the prop. There is where a ground adjustable comes in.
