I just got my 2nd and very fast response from the ROTEC radial folks- they could have started on this newer larger R3600 radial a year ago but, for obvious reasons, needed to recoup the cost of the R2800 110hp radial. Sounds like they are ready to take some orders and I am seriously considering jumping onboard. 150hp! Listen, I think the engine is the 800 pound gorilla here, not the prop. If I have to swing a shorter prop, can't i still have it made in alternating woods that look pretty darn close to an original? If I catch anyone walking up to my DR1 and whipping out a measuring tape to measure the prop, he is going to get a swift kick in the .....
Still, I have 2 years before I am flying, and maybe someone will resurrect a rotary for us!
thank you ALL for your contributions here- makes life interesting!
