Cool Prop types

I am putting together a extra 330 78" wing span. running a da 35. and a 20x10 prop to start with. My first time with a bigger airplane. I have been flying for 11 years now
We fly off of grass at the club field. Wood props do not last long out there. I have seen the carbon ones. Can I use a master airscrew or an apc prop with this setup?
Any advice would be a great help.

Yuck on the MAS or APC on a gas engine.

If you want a good prop get a Falcon Carbon at whatever size you intend to fly

Also, 20x10 really drags the top end down, I'd get a 20x8 falcon personally or a 19x10 if i were putting it on a warbird

APC makes a 20x8w (wide) prop that I used to use at a pretty rough field I used to fly at. That's a big heavy prop, but I was tired of breaking the wood, and CF props are expensive! Agree with Barracuda. 10" pitch is likely a bit much for an acrobat. Might be better used on a really clean military type that's not looking for the vertical performance an acrobat might be looking for.

Default No to mas

master air screw are just terrible. Too much flex in the blades. I'd never run an APC on a gasser too sharp you outta see the scars on my fingers from an APC on a 1.60.
​​​​​​​i agree with Andy Falcon carbon fiber

I've been using wood Master Airscrew 20X10's for many years with a 50cc engine with no problems. They shatter on prop strikes protecting the engine during abrupt stoppages. Dan.

Yup. I use the same reasoning. I'd rather break a prop than bend a crank.

That's why God invented sandpaper. Anyone running APC and flip starting an engine, from .60 on up, generally figures that out pretty quickly.

Thank you for all the info. I will get a 20x8 prop. As for flipping the prop I will be using a rolling chicken stick. or something like that. I am minus half of my pinky finger from getting my hand in the prop. Cut it clean off. As for apc props. We all use them on our nitro planes. And sand the edges before using them. The props can be low to the ground. Wood props do not break. But they chip from the grass. But I have hit the ground with the apc prop on my nitro planes and cracked the firewall. Nose over after landing.

Default It wasn't the back side

It wasn't the backside of the prop that got me....I got in a hurry to get a flight in between showers. Forgot to retard the throttle
