Just got the 912s running today. I didn't do much since I didn't bring any hearing protection but I did generate some questions: 1. At 12.5d at the tip of a 70" Warp taper tip I'm getting 5500 rpm WOT. Any guesses on what I should try next to get 5200? 2. It took FOREVER for the temperature to come up and the most I saw was CHT 175F and oil temp 170F. (5 minutes run time.) I have a water thermostat. I'm contemplating the oil thermostat but will wait for more testing. My thermostat is 190F, so I expected the radiator to be cold, but it wasn't, indicating that the water temperature was probably much higher than 175F. My question is: should I run water temperature and pressure? I'm thinking I could incorporate these into the thermostat manifold. (It's downstream of the water spider.) Is it worth the hassle? (Particularly water temp, which Rotax says I MUST have for the regular coolant I'm running. I've got a GRT 2000 engine monitor so the display part is easy.) 3. I'm idling at about 2200. What should I use for us Kitfoxers? (Manual says 1400. Is that possible?) Thanks in advance for the consideration. Looking forward to flying when my cowl gets done.

I am deep into the eighth year. I started the engine about three years ago but have been rebuilding building the cowling to fit the new gearbox since then. Currently building a hangar and house so I do not see getting the plane flying this year.
