Hi Guys -
Thanks for all of your input...it's been most helpful
Personally, I am okay to spend a bit more $$ to get something extremely high quality / high reliability. I have zero experience with Evolution engines, but have read a lot of good reviews about them. What say you guys about that?
Regarding OS engines, now those I have quite a bit of experience with but only glow AND my experience has been a hit or miss. I've been running and OS 60 in Goldberg Protege' and it's been terrible (I have always figured though that I must be doing something wrong with it). I wish ENYA made small gassers!
And I have some experience with Saito's but again not with any gas variety.
I have never heard of NVH engines, but have been very skeptical of a lot of the stuff coming out of China and Japan these days.
Anyway, the OS 10cc is supposed to run on a 50:1 mix which would tell me that the engine must be made very well and that it is also burning fuel very cleanly. Am I correct in this assumption? My project that I want this for is a Great Planes Ultimate 40 Biplane. I've seen these fly nicely on everything from a OS 46 up to a Saito 82.
Looking for ideas, guys, so please keep the comments coming
