Paul,
I am new to your news letter, I own a tailwind (w10) upon which I am
thinking of installing a Mazda rotary engine.
I also own a machine shop with a new 4 axis Doosan vertical mill,
and electrical discharge machines, cnc lathe, etc.
I would like to help with any production of parts for
engines/airplanes/etc that comes up.
Keep Flying!

Your sure can Randy. Thanks for contacting us.
We need a new gear box kit here in the states. The gears themselves
are off the shelf Ford auto trannie parts that the builder can buy
and install. That cuts the product liability exposure on your end.
Take a look at some of these Rhino's 3D"s. and tell me if any of
these ideas appeal to you. I also have a bunch of pictures and 3D's
on rotary powered Tail Winds as well.
I am also available for free Rhino help with about 12 years
experience.
Same for micro-controller programming on any automation projects you
may have in mind. I have already done three. A coil winder, a round
tube tig welder and a linear tig welder. I can also visit if you
need me as I fly UAL standby nearly free.

I am hoping that someone will step up and fill the PSRU and electronics
gap left when Tracy Crook retired. I am currently building and will
definitely be using a turbocharged rotary for my amphibious plane. I
will need a reduction unit and a controller for ignition and fuel
injection. My plane is a pusher so I would like to find a PSRU that
would change the rotation so I could use a common 72" prop in the pusher
configuration. If the PSRU is reasonably priced then I would much
rather buy one than try to make one. There are a lot of great ideas
coming out of this newsletter but for me it is trying to find time to
work on all of the projects. I would rather buy some of them and since
I'm not a machinist the PSRU will probably be purchased if they are
available. Just my thoughts.

The EFI is real easy to do it your self with this very easy to program
micro controller. I can give you a lot of help to get you started.
The big advantage is no secret source code. Open source. We can all
work together and share our mixture maps.
A. The Maximite comes completely assembled.
B. Easy to learn by trail and error. You do some thing and the result
can be or is printed on the screen. Here is a simple program. Most
BASICS are the same with minor variations.
PRINT 2+2
END
The number 4 is printed on the screen.
C. Buy a Maximite and play with it.
D. You don't need to assemble it. It comes assembled.
E. CircuitGizmo.

F. Trial and error. Ask questions on here or Google.
G.

H. Hang in there Perseverance gets it done.
In fact here is a BASIC program that is an excellent start for an EFI
and EFIS.
If it has a ' in front of it it is a comment.
