I am at present checking into the possibility of using such engines for
my Zenith 750. I just started the kit, but it will not take me long.
Past suggestion to me indicated a single rotor 13b is what I need. I
need about 125 HP + or - ??? The airframe can accept up to 140 HP and
max 280 lbs. 2 rotors may be too heavy ?
By going this route, I am really stretching the word "experimental"
What I am looking for

1) an engine, and who can overhaul it to aircraft standard.I hear these
engines are almost as fuel tolerant as turbines. So can I pour anything
flammable into the gas tank?

2)engine mount and redrive.(I don't want to go near anything made in
China!) Standard Cont 0-200 mount I just send the factory a cheque!

3) ignition system and fuel injection system, (do I need to mix oil with
gas? what oil are being used for lubing the tip seals?) Canadian company
called EM-3

4) the spec for radiator cabin  heater and muffler,I want a warm and
quiet airplane.

5) a rough price for the everything Fire Wall Forward. What about
insurance ?? I already know if it is the FAA in the US, an engine like
this , they would stick the builder with 40 hours of testing instead of
25 hours. So I fly a week more.
The standard engine for this bird is Cont 0-200, 100 HP, but this bird
will eventually go on floats, so the extra power will be needed.
I am buying the Aviator's Guide to Mazda Rotary Conversion  soon.
The other choices of engines are Corvairs (120HP), Rotex 912 S (used)
100HP, Viking Honda Fit engine, Lycoming 0-320 150 HP, but I hate the
expensive 1940 technologies.
Thanks for your help.

An 801 is more suitable for a 2 rotor. See attached pictures.

Contact Richard Sohn for a one rotor for a 750.

1) Many people can overhaul it as stock is well up to or exceeds aircraft standards.
Gasoline is required. Best is P-port.
