Terrific little engine. I've read in a couple of places that 912 engines are not terribly susceptible to carb icing, but operating on the principle of "better safe than sorry", I've been thinking of adding it. I wondered if anyone has any experience with the unit shown at http://www.ultralightnews.ca/bing/carbheater.htm. Seems like a simple solution. Along the same lines...anyone heard much about the 912XTRA piston conversion kits - good or bad?

If I climb to 6000ft I get about 23in.Hg MP at full throttle. What I want to know if how do I now set up for a reasonable cruise. It doesn't seem to make sense that you can run full throttle and set the RPM to any value you like - at some point the prop will be too course. I'm looking for some practical tips from owners of VP props on how they set up MP vs RPM. Am I missing something here? Dave ----- Original Message ----- From: Thom Riddle Subject: Re: RotaxEngines-List: RPM vs MP --> RotaxEngines-List message posted by: Thom Riddle This information is given in paragraph 10.1.1.1 in the Rotax 912 Series Operator's Manual which is available for download at http://www.rotax-aircraft-engines.com/aircraft/aircraft.nsf/index? Openpage It does not matter whose prop you are using or whether it is a manually adjustable or CS prop. The combination of MP and RPM is what matters.

The nice solid body has been replaced (in the Mark 2 and Mark 3 versions) by a casting around a bit of bent copper pipe. Not as asthetically pleasing but i am sure a lot cheaper to make. Even the Lockwood catalogue shows this mark 1 version. I am sure if you buy from any of these suppliers you will get the mark 3 version. The difference between the mark 2 and mark 3 ? They deleted the temperature gauge ! I have one, or rather a pair. It does not work if the water temperature is allowed to get too low, and unfortunately the time you need the carb heaters working (cold) is when the water temperature is low. Baffles required.

Unfortunately the builders technical sight is closed, but one of the builders had the piston installed, but the engine seized in about 20 hours. This would be third hand information, so take it for what its worth. Jim
