Paul;

  I am planning on building a T-51 and I would like to use a

rotary

engine. However, I am afraid that all of the rotary engines I am

familiar

with are too heavy. I am hoping that there is something that you are

aware

of that I am not. They are currently using the Rotax 912 and 914

engines. I

would like to use an engine at 200 lbs or less, but I do not know what

is

available in a rotary, if anything, that will fit that description. I

get

nowhere with Diamond, they bought out Mid West, and I am too old to

want to

wait for Freedom-Motors. Any suggestions.

Thanks,
Mark

Nothing available right at the moment.

Paul,

any knowledge on converting a Norton Motorcyle engine? I understand

these

bikes were not too great a success, so there might be a couple of

cheap ones

around. With a little turbo they should give 120-150hp.....

Any thoughs?

The Midwest rotary engine is based on the Norton. Nothing else on the
Norton.

able to get an answer from Diamond. How difficult would it be to convert a
Norton engine for aviation? How would I go about finding a Norton engine? I
would very much like to use a rotary in the airplane I am planning to build.

Thanks,

As I recall it was a one rotor so it would not have enough power.
I could be wrong about the one rotor part. I suspect  the collectors
of Norton bikes are not going to part with them cheap.

hi Mark,  i looked into the norton, which is a 2 rotor, several years ago.
they never left england, because they were only built for the police
departments.  at the time i had no luck at all finding one.  you need a
mazda single rotor. good luck walt.-

The Midwest engines came in one (~50hp) and two rotor (~105hp)
configurations.
