Sorry if it's been posted before, but it's the first time I've seen it, and it reveals many very positive things about the Renesis Motor, and even gives some nods to RX-8 owners:

Exerpt -

The engine continues to improve with each hour of flight. The very close tolerances in the new engine require an amazingly long break-in period. Temps keep coming down although the coolant temp coming out of the block is still higher than the 2nd Gen engine as noted previously. The oil was changed from Shell Rotella (a very good mineral oil) to Mobil 1 Synthetic at around 5 hours. This further reduced oil temps to the point that it is no longer a factor under any climate or flight conditions. If the OAT is less than 90 degrees, the oil temp is actually too low for optimum efficiency. 180 seems to be the sweet spot and it runs about 20 degrees below this most of the time. A cowl flap will solve this problem. Temps too low is the very best 'problem' you can have : )

Cool, ummmm...is it me or is this a 3-Rotor Renesis???

They had to design a special ~3:1 reduction unit to run Renesis motors, very spendy but not in the grand scheme of things. Buddy of mine is looking to put a 13BT in his RV10 project, can't wait to help him out with it.

How much would that cost, and, is the use of the Renesis or 13BT widespread now in small aircraft aviation?

Thanks.
