Ed,
Some on the list are going to laugh knowing my experience, but at the risk of that let me throw this out there:
- The very coolest feature about your airplane will be that it flies. Everything else is fine tuning and to the extent you spend time on it, it prevents appearance of the very coolest feature. - Stay with stuff that has already shipped, in thousands of units. Stuff that has not shipped yet, probably will not have when you are done. Stuff that has shipped in hundreds of units probably "sorta works". Even some stuff that has shipped in a couple thousand units is not well engineered. It's buyer beware. Do your homework. - The one thing you can't redo later is the weight and precision of the build. Build it light and strong and precise, get it flying, buy "good enough" avionics at the last possible moment, and enjoy 5 years flying it while your peers make theirs perfect. At that point you will know what might really change your life and you can redo a few things.
I would recommend a IO-550. Either factory new or rebuilt by an excellent shop like BPE.

They say they are 1-2 years away from cert. engines, experimental sooner. 200 hp should be plenty for takeoff, since much more torque available, and the 200 is there all the way up to flight levels. Fuel savings in 2000 hours will pay for the engine, plus no worries about 100 LL. Anyone else looking at this engine? Ed Gray |
