On Friday, June 8, 2012, N120EJ soared into the air for all of three minutes.  Cylinder head temps were going towards redline so I had to shut down the engine and return for landing.



After some work on the baffles and re-pitching the prop it again took off on, June 11, 2012, only to have to return to land.  Temps were still high again.  A phone call was made to the Engine Rep in Fresno, Jim Cormick, and he wanted pictures of my baffling.  When he called me back he told me that I must be a Lycoming/Continental mechanic as the baffling was all wrong for the Jabiru.  I then ripped the baffling out and installed some new shorter, smaller baffling.  

On Wednesday the 13th I took to the air this time I made it around the pattern.  The temps were still high but within limits, but the elevator control felt wrong and trim was going the wrong way.  Again work was done on the airplane. Pilot's control stick was move back; elevator control mass weight bar was move so that the elevator had more down movement;  trim wiring in cannon plug was switch so trim would go down when it was press to go down.



The next flight, June 18th, I took off and actually went around the pattern twice before having to land.  This time it was the oil temp.  It was getting high.  Once on the ground found out that I had put the wrong type sensor in the computer program.  It was reading 56 degree hotter than it was.  I was also able to download  a flight log of the flight.  It showed that Channel 4 and 5 were 500 degrees less than 1,2,3,6.  



Changed the EGT probes out by putting 3 into 5; 4 into 6.  Ground run the engine and the cool cylinders stay on channel 4 & 5.



Called MGL and they are sending a new EMS.  So I'm waiting to get it and will fly it again.



Overall, I'm impressed with the way the plane handles in the air.  It is like a fast sports car. It leaps into the air.   I’m looking forward to the rest of the flight test program.



Here is picture on the ground.

Hi,



I would love to hear some more details about the changes you make to

baffling - my Jabiru engine still runs very hot and I'm trying to make

some improvements currently.



Also, I'd be interested to hear cruise speed / RPM / Fuel Burn.



What propeller are you running?



Regards,

-Carl.

Rick,



Thanks for posting the trials and tribulations of initial flight  

testing of a non-standard engine installation; keep up the great  

work...you're providing a dose of reality to our collective experience  

in the world of experimental aviation...best of luck at banishing the  

gremlins soon.



Where are you based? What are your OATs?



Fred



PS:  ...very elegant paint job!
