Neil,
We have found that to idle well the rotary needs individual throttles. Rotec makes a throttle body that doubles as a vacuum sensor for their fuel injection. We use a similar FI now. We use our own butterflys. We will need a individual slide per rotor. Rotec's looks good though.

Bill, I have been told that Rotec in Melb Aust, makers of a small radial, also make a brilliant slide throttle. I am happy for the rotary to idle at 2000, or a little less at it give a prop speed of 6-700. Again it is up to we owners as to what is acceptable for the given cost. My TB cost $110 from the wreckers. The original dual TB came from EFI and cost more like $1200. They also make great gear if you can pay. Neil

Neil,
I like his ports, not the same as ours but a good setup also. Ours are configured with the butterfly close to the inside. It really seems to help the idle. Our PSRU has an adjustable mesh and everything will idle down to 1100 engine RPM no problem. (while swinging a prop on the dyno.) I plan on a proper slide throttle, (hard slide with bearings), to go even further. I'm on Paul Lamar's newsletter and while there is a lot of dross, there is some good info there. Recently there was a post from someone that had info on the Merc. C111. I got several items of information from the drawings and pictures, also 1 patent. They put the throttle butterflies exactly where we do.

Bill, as you can see in Christian's housings, the water galley is sealed being the cold side anyway. This is a popular way to stop water leaks on the P port. You can also see where the plug fits up against the housing. By the way Christian is a wizard on rotaries, he can pull down and get going again in a day!!! I hate people like that, he makes me look stupid!!! Neil.
