Thank you, thank you. I try hard to please. :)

 

Thanks for the update. It's a little scary dealing with a company so far away, but Max seems like a straight up guy so I never really had any doubt he'd come through. Just took a little longer than I'd hoped.

 

400HP. Yes. he mentioned that. A bit lower at my max rpm of 6300, but still - plenty of grunt. :)

 

 > From what he explained to me was that you will get more boost for a slower turbine rpm,  

I thought it was less boost for the same airflow.

Oh! Nice touch.

 

 > Now im thinking of changing prop size. ( currently ivo 70" variable high  pitch 3 blade ) can you make any suggestions.  

 

Well mines a wood 68 three blade with 314 blade area from Performance.  It'll accelerate the plane to take off in 1000 - 1500 feet at 4300 rpm and climb quickly at 5000. It'll even climb at 2300 rpm. Should be ideal for about 280 hp in cruise and should get me a better top speed than a variable pitch. Given that you need 2000ft to land I'm not sure a variable pitch prop will buy you anything on a Cozy, and it'll probably cost you at the top end. Are you building a Cozy or an RV? I forget.

 

Cheers,
