Hi,
    Just wondered if anyone is making a single rotor wankel out of a dual
rotor Mazda engine. It would seem like a terrific ultralight engine. I have
talked with Atkins and have his prices. Seems there wouldn't be much to it
as far as possibly regrinding the crank, from a Mazda engine, for one rotor
and basically putting it back together as a single. Anyone have any
experience or knowledge with this conversion besides Atkins? Thanks in
advance.

Hi Mike, There is a subgroup of this news letter doing just that.  The big stumbling block is

the single rotor eshaft.  We have a contact in Australia working on that as we speak.  Frank in
Canada has already made one and is making another. See attached. We have ordered some tension
bolts for the single rotor and with any luck we can obtain some single rotor eshafts, then with
some minor machine work on one of the stationary gears we will have a single rotor.

Hello:
On the single rotor setup shown, does anyone know how much it weighs?

Has anyone weighed each piece individually, rotor, housings, e-shaft, etc?

Does anyone know if the gray cast iron housings in the picture are also made in Aluminum?

Is that a manuel five speed flywheel or automatic flywheel in the picture?

What kind of PSRU are they using with the one rotors?

Does anyone have a cad drawing of a prop hub for Tracys PSRU with dimensions or know of a web
address where I can download it?

For those interested in the manuel 5 speed PSRU. I ordered George's manuel, and he answered one of
my questions, about how many hours he had on it, and if he had any problems, he said "I have a bit
over 300 hours on it, no in-flight problems yet."
