Dear Sirs ;

I wonder if you could help us.

We are contemplating the use of a rotary engine in pusher configuration on a gyroplane.
We may have access to a scrapped 20B engine.
We need about 120 to 130 HP only.
Has anybody any experience with a single rotor version of this engine to produce that kind of power reliably ?

Weight is of course an issue.

Sincerely,

Woody DE SAAR

There are a couple of people on here working on single rotor versions of the RX7 engine.
130 HP is a bit much HP for a single rotor Mazda. I suggest a stock two rotor RX7 engine.
If weight is a real big issue I suggest a 115 HP 2 rotor Diamond engine.

BTW how much do you want for the scrap 20B engine and what kind of shape is it in?
