Don't want to create a new thread if one is out there but I'm at the point I need to order my prop. If there is a thread someone please let me know. I want to use a composite prop and with the aft CG issues and ramp appeal want to use a 3 blade. Easy enough I thought. Whirlwind was my first choice but they do not make one for the Lycoming 390 or Superior 400 and no the knew prop coming out is not good for anything over 200 hp. That leaves MT. Doing my due diligence and keeping with "Total Performance" it's difficult to find performance specs for this prop. One builder reports 171 knots (TAS) flat out with consistent 160-161 knots at cruise. This is not much data to make a decision on a MT prop. What I did hear earlier this week that Hartzell submitted there Raptor series 3 blade to Vans for performance evaluations for the 14. Suppose to be ready in May to give feed-back to Hartzell. Maybe someone at Vans could give input? If I wait till June-July to order my prop I'm cutting it close as I need to finish cowling after prop install. Want to be flying by Dec 2019, I hope.
