Thats a tough one without being there.  Possibly too rich on high power, burning extra fuel, something got too hot and went kaput?  some of those thing that happened in throttle back are normal.

True, real hassle to trailer it, but just dont push things. Things will go wrong...  guess how I know. 

Slow down, take a good look around for leaks.  start over with some tuning, get some data on a cool engine.  Make sure both rotors are working etc..

Take a night off then report back with more data...

Gents,

 

I am at a total loss!

Bruce Terrentine just rebuilt my Renesis, I hooked everything up, did all the tuning for the EC2, and started the high power runs to get the one hour max throttle time before the first flight.  I'm 35 minutes into it (5 - 10 min at a time for temperature), and the engine went from 4860 static RPM at WOT to 4600.  At that time, I still had good oil pressure, fuel pressure and mixture reading was good.  I throttled back to idle and shut it down.  As I throttled back, the oil pressure went from high 60s to 36 and the mixture reading went from 8-9 bars on the EM2 to 1 bar.  After I got out of the plane, my father who was watching the run, said I had about 8 inches of flames shooting out the exhaust during the entire high power run.

I don't even know where to start, or how to fix this.

To add to the problem, I am supposed to move from Leesville, LA to Fayetteville, NC on 24 July.  I really don't want to have to pull the wings and trailer the plane.

My first call was to Tracy, but he is out of touch until the 23rd, so no help there.  Is there anyone with enough experience and time to help?  Anyone close enough to Leesville, LA to make a trip here?

Feel free to call 337-208-8053 or email me direct candtmallory@cebridge.net

I'm really desperate!
