Rich I think Andrew has got the correct answers. Cannot say it any
better. These engines are bullet proof if you keep them under the 200
degrees F. Naturally they also run better with oil. Keep these temp
in line and then do not be shy with the power. I just recently found
I did not hook up the lead plug when I changed the coils and the thing actually
ran quite well. I still say this is impossible, but no there was no
trigger wire to the LEAD plug! It was running on the trailing plug only on
one rotor. I certainly have to eat a lot of “crow” over this, but it still
ran reasonably well with a miss or two. Once you get
used to the noise they are a brilliant engine. Neil.

I think you got some loaded questions there.
Best power/speed is a combination of factors involving engine, prop,
airframe, weight, ego, wallet etc.
For maximum TO/ cruize etc. same applies but your nerves, wallet &
cooling are probably the limiting factors.
I have a quadrant with 2 levers, 1 marked noise, 1 rpm, I find it best to
have noise set at loud for takeoff & rpm at fast. For cruize noise at not so
loud & rpm at slow. Landing, noise at less, rpm fast.
Seriously, You'll work out your best settings when flying off your initial
hours.

Greetings all,
As I approach finishing my aircraft (probably in the next year --
although I have been saying that for the last three years,) my thoughts are
moving to how to operate the rotary without damaging it and gear box and
achieving the best efficiency/ speed/ power with the above two criteria
in mind.
My setup is as follows:
Normally aspirated Renesis
Tracy's EC-3, EM-3
Tracy's RD1-C
Ivo Prop with C/S/ attachment
Pusher configuration
So Mike Bush says the best configuration is to fly with wide open
throttle and control power with RPM (lowest possible consistent with smooth
running) and LOP
Of course this is for cylindered engines.
I know that the Otto Cycle is the same for ours and theirs but my
question is, from those familiar with the running of these beasts:
Do the same parameters hold--- or what is the best way to run the
engine.
Additionally what is the maximum TO RPM for the Renesis and maximum
Cruise RPM, if there is a difference... as well as the parameters in which the
engine (of course properly cooled) can be safely run.
Thanking you all in advance,
Rich
