Dear Matt;
I hope it is helpful.
My OS GT now runs with Mijzlik carbon fiber prop 18x10. It reached 8200 rpm, but I set to 8000 rpm. The prop noisy is too sharp and loud.
As I mentioned already, It runs on Hyde soft mount and with Hatori header/Canister muffler. Even it rotates carbon prop much faster than other wooden props such as Menz, Hawk (18x10, 7500 rpm), I feel less trust pulling my Smaragd which is much over than 5.0 kg. I am looking for 19x10 carbon prop, but difficult to find this size of prop. Ans also I am struggling to take off some weight now.
I hope to hear your good weekend flight news.
Regards
Don't be afraid to modify the wooden prop if it presents too high a load. I suspect the Hawk is a wide blade design. We don't really need wide blades in pattern. Just make sure that blade shape is preserved on both blades.
Rather than a 19x10, let me suggest an 18x12 apc. The engine seems to be comfortable turning in mid 7's so more pitch will be better and quieter.
If you can't find a 19x10 carbon and you really want one, I have one I will sell you. PM me with address
