I've been enjoying flying my FT Spitfire with a 1000kV and a 8x4 prop. I seems to be going great, apart for a shortage of trust right after launching. Usually I'm able to gain height and build up speed, but yesterday I didn't and "landed" with full throttle, breaking my propeller. Now I only have a 9x6 prop left. How would this work? Will the engine struggle to run such a high pitch?
