Sorry to be a little slow at updating info on our Turboprop, Boli, our TP is designed to be running at a much higher load but much lower RPM. The ideal prop would be turning at 5000 static and unload only up to 7000RPM. This would ensure max output and longevity of engine. Please use no smaller than 24x16x3b, as it would provide 5500/7500RPM, while a 24x20x3b would achieve the sweet spot of 5000/7000RPM. Anyone has suggestions on people to contact for prop making, please let me know, as we like to develop something like a 22x22x3b and 21x21x5b. Thanks in advance!
