Hi Ed, I am still here. Done flying. I still have the AVID with th= e single rotor operational. Don=E2=80=99t know what to do with it.

On my third flight I did not pay enough attention on the ru= n up. When I took off, lost power and the engine quit. Put it down in a cot= ton field with out a scratch. Had to replace the rotor housing and the seal= s. The reason was over heating because of low coolant level.

Bei the time I had fixed the engine, I realized it was time to= call it quits with all the experimentation and test piloting while I have s= ome time left to enjoying some ground time.

=C2=A0

I don't know what = to call it, but my single rotor is running on something the supplier is ca= lling fuel injection. In reality it is a somewhat advanced Ellison carburet= or. It operates without electricity, has full mixture control and a primer, = which can be used for over riding vapor lock in the fuel lines. So far, I= have around 50hrs run time on the ground on two different engines including = 1hr in the air. It may be supplied from a fuel pump or gravity feed. The e= ngine never have staring problems. The air time was 3 flights, with the thi= rd one ending in a dead stick landing because of engine overheating.

The 12A based single r= otor flows around 10 GPH of gas at 6300RPM WOT. <= /o:p>

I have not seen a carburetor, during the s= ingle rotor development, performing comparably.

Hope to be in the air again soon.

Something that might be of interest is that the ORIGINAL Pow= ersport engines were setup with Airflow performance fuel injection.
