Sure runs strong though but no way is it going in my plane.
I have read allot here about how these engines are smooth operators but I don't see it. My father had the 40 in his DP extra and it would blur the tail unless the wings were on. Still, my os 160fx is smoother than these two.
And don't anyone tell me to lean the low end to smooth it out, if it gets any leaner it wont transition.

Take the refund, and get a Twin that's smooth. I've seen alot of servo gears that users have had to replace due to the singles...NO MATTER HOW GOOD ONE ***THINKS*** they are. The harmonic, and dynamic balance will *never* be what a twin will give you, and nobody that's in the know will dispute that. Go for more power, smoothness, quality of construction, longevity, and backing on a motor like this! These motors cost a small fortune! Why buy twice? I'd rather spend twice the amount on a motor than not be flying at all...that is why we buy these motors in the fist place. I've seen shakers, I've seen reliablity problems, and I've seen motors that would 'nickle and dime you to death'...it just ain't worth it...look around you. If you see a motor running maintence free, and trouble free, BUY IT! It will save you money in the long run.
Now for the naysayers...did I mention a brand? NO! So before you start a brand war, better think about what is running trouble free. I don't think it takes a rocket scientist to see that!
