Dear Paul

I am a newly signed up member, I have watched the website for a while and
recently joined.

I have a self built quickie with a 0235, but also have two 13b's.

And plan to convert one of them to my plane, I looked at Tracy Cook's
injection but it he says his system will not hand prop.  As I am limited to
100bhp (being in England, something to do with our air being different to
the rest of the world?).

Anyway because of that I planed to use the rotary direct drive, so the 555
injection on your web site.  Looked interesting, is it possible to obtain
more details and the pcb's.

Has anyone built one using Lightspeed MAP output to factor in load for a
constant speed prop?

If I am out of sync.

Clive

I will be working on the injection system some more when I get back to the
states next week. I don't recommend a rotary for direct drive. You need the prop
to turn at less than 3000 RPM to be efficeint. At that RPM you
would be lucky to see 50 or 60 HP from the 13B rotary while the weight
would be well over 200 pounds. For direct drive there is no replacement
for displacement. You might look into a pneumatic starter for the rotary.
That should be less weight than a alt, battery and starter.
Plumb high pressure air into the combustion chamber after to dead center.
The Russians do it all the time.
