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
