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?

Test[FlyRotary]
I agree that my
Renesis engine was only producing about 70-80 HP on the small red
primaries. When I run only on the primaries with the secondaries
off and the
cold start line grounded my EM-2 tach RPM
doubles - 4000 RPM shows up as 8000! My fuel flow numbers
and HP numbers appear also to be doubled!! The 140 HP probably was
actually 70 HP! 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). Is this due to the rev. limiter
Tracy may have
included? If so - does it control engine speed by disabling the
secondaries?
After the fatality several years ago because an apparent
injector may have been disabled by foreign matter, I was determined to have duel
injectors and ignition for each rotor. This morning I replaced the Renesis
red 295 cc primary injectors with blue Renesis 495 cc injectors.
When
running with the secondaries on (540 cc I believe) and the
primaries off I get full static power. Because I've changed
intake and injectors I will need some time to calibrate fuel flow before I can
accurately report static fuel flow numbers.
