Your intake was similar to mine. What did you do to change it? What is full static power?

[FlyRotary] Re: 295cc vs 495 cc Renesis Test[FlyRotary] I agree that my Renesis engine was only producing about 70-80 HP on the small red primaries.

However - when I operate with the primaries off and the secondaries on the RPM and other data is not doubled!! Somewhere above 7500 RPM the RPM number on the EM-2 goes to Zero (0).

Can’t you set it to a = higher rpm??  8K is not supposed to hurt the Renesis with the lighter = rotors, etc.

Tracy's rev limiter works. Problem is staying away from it = on take-off with the MT electric prop.

Dennis,

I don’t think that doubling thing is = supposed to happen except for the fuel flow thru the other set of injectors.  I certainly could be wrong tho.  I don’t know what would happen = to mine above 7500 rpm because I couldn’t get there if I threw it off = a cliff!  :>)

 

You lost me with the 540 CC secondaries thing = at the bottom.  Did you mean 840 CC??  Your intake was similar to mine.  What did you do to change it?

 

What is full static = power?
