Default Interest in carbon copies of Rev-Up 11x7.75 props

There are a couple of cottage shops that might be interested in making CF clones of out favorite props. I thought the Rev-Up 11x7 3/4 would be a good one to copy. Because I only have one!
How many people would be interested?

Chris,

Sure, might be interesting. A slightly wider gamut of props might be needed though. Any idea on what pricing might be like?

One guy makes a bunch of Rev-Up clones for the C/L Stunt guys. Raw they're 22 bucks, finished and balanced they're 32 bucks.

Chris,

how the heck does one balance a CF prop!? Can one actually sand them or are they dynamically balanced at the hub?

Just curious....why would one go through all the trouble since a perfectly fine alternative is cheap and available? APC 11x8; less noise and more thrust from the same power source

If it's Academic curiosity.... I totally get that.

I never used the Rev-Up 11x7.75. I used the 11x7.5. If you actually pitch gauged a Rev-Up it was always underpitched. BTW, I have a bag of 11x7.5's if you want to copy one of those. In fact I should try one just to see how it compares to an APC 11x7.

I just sand them like any other material. It's just like a glass prop. The difference is that if you are trying to shorten one, a saw must be used.

I'll keep that prop in mind, Tony. I'd like to try one if you have one to spare, too.

Some guys that used those props in the 70's and 80's and still use them today, feel they're pretty good. I don't know if they are better still than modern props or not. I've just started to gather a prop collection for high rpm 60's/61's and simply am wondering about the matter.
Which engine are you using the 11x8 APC? I noticed, like Tony said, the Rev-Up's were shallower in pitch than advertised. APC's seem to be right on so your engine must be a monster.
