REFLECTOR: N151AJ first flight

[Andrew Ellzey]

John,
 
I have now flown my aircraft for about 4 hours, and the #5 CHT has been consistently higher that all of the other cylinders by about 30 degrees. Yet its EGT is very consistent with all of the other cylinders. I am leaning toward a bad CHT probe, I am going to swap #3 & # 5 to see if the problem follows. And to answer your question, I don't have an EI, I have all of my engine indication  shown on my Blue Mountain EFIS One unit.
 
Andy

>N151AJ, Velocity XLRG made its first flight late this afternoon at 7:50 pm at ROG, Rogers Arkansas airport. I was pilot in command for this first flight which lasted 1/2 hour. My aircraft flew quite well, my flight controls were very light, any adverse movement came from me not the aircraft. Once I lightened up on the control inputs, it flew like a dream. I climbed to 1000 AGL and stayed in the pattern for several circles around the airport, watching all engine indications for any problems, and just getting use to the light flight controls. I opted to leave the gear down for this entire flight, didn’t want a gear up landing on my first flight. I really had to fight the temptation to pick them up. My #5 CHT bumped redline, which I have set to 450F, (Lycoming IO-540 operators manual states 500F MAX) once or twice, early on after takeoff. I was however able to lower the nose and cool it down pretty quick. After this initial redline it seemed to fall in
 line with the other cylinders, maybe 20 degrees higher than the others.   
The higher temp could indicate detonation.  Do you have an EI?

>I have two oil coolers in series, one in the front, standard Velocity nose NACA scoop, and one in the rear. I had already completed two high speed taxi test about 40 minutes earlier, so everything was already warmed up, before I even taxied to the end of the runway, oil temp was already about 230F before I started my take off roll. My Oil temperature quickly cooled down to 210 degrees and stayed there through the whole flight.  I did a go around on my first landing attempt, a last minute gust at the end of the runway pushed me off to the  left side of centerline,  in about a 15 deg. crab. I probably could have saved the landing, but elected to do a go around to try it again. Second time was a charm, touching down on both mains straight down the runway, I even held the nose off for a light touchdown. Yea it surprised me also. I forgot to save the flight data on my BM EFIS One, so my memory will have to do for this first flight. I had my wife video
 this first flight, but either my camera, and or her unsteady hands make some of them too bad to share. This link should allow everyone to view the takeoff and landing.
