Greetings Luis, The airframe is an Aerocanard XS. I too am far (about 1 year) from making noise, except for the swearing at myself when I make stupid mistakes in construction. I will, hopefully, rebuild the engine this winter (Chicago area) even though I was told that the engine only had 14K on it before the back end of the car from which it came was mashed.

 

Where you located?

Rich - out of curiosity, what airframe did you build?  I have a 20B to be mounted on a Velocity XL but am faaaarrrrr from making noise :(

Subject: [Non-DoD Source] [FlyRotary] How do you run these things????

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
