Fuselage is finished and working on the tail for my 750SD. I hope to have significant progress by end of this fall. Decided on a Dynon package and will probably be ordering it soon.

That brings me to the engine and prop choices.  Although I spoke briefly with a couple of builders about engines at the beginning of the year, (thank you) and although the price gives me pause, I'm still considering the UL520T (UL520iST) engine.  With the passage of time I'm hopeful some folks may now have more knowledge of this new engine.  I've spoken to both UL Power in Belgium and Ray of Kaolin Aviation and they're confident there will be no heat issues, etc. etc.

As this is my first build and I know several of you folks have UL engines and are very knowledgeable, I would very much appreciate any and all comments on this engine and props for the 750SD.

Thx

Bob
