Ttail, that is a big difference between the pods. Am I reading it correctly? The one with arrow (7) is 199deg C and the others thus higher? What is the highest? Can't make it out on the photo. What I noticed on the last flight and I am not sure whether I am imagining things, but it felt like the cockpit was warmer than normal, after stopping engine and climbing out and walking around the YAK, that the left as standing in front of the plane is warmer than the left. Is that normal? That is why I thought I'd like to check the temperature probes, where they are, etc. If it is measuring the coolest cylinder, some of the others may become very hot indeed even if the coolest is still in spec on the CHT gauge. I don't have a monitor system to measure each cylinder. Pretty much a stock YAK. What I also found is that it is smoking a bit while on idle even after flight from righthand side exhaust plus the righthand side exhaust have a little oil on the outside which come from between the most bottom piece and the next one up, ie most bottom joint. But it doesn't look like the normal oil that is black and drip out of the exhaust when stationary, so it could be smoke system oil, but I somehow doubt it. Smoke system off and still oil doesn't seem possible. AMO reckons rings might need to be replaced.

It was previously based in Europe, where it had some decent competition results in both the Intermediate and Advanced categories.

Last week I was in touch with the seller. I'll be back in the States tomorrow, and hope to work out a time to go see it next week. There is an M out in Oregon that I'm interested in as well. That's why I was looking for impressions from people who have time in both. I really like the way the M flys, but what if I like the 55 better? With a nice example of each type out there, it just seems like its a sign from the Gods!

I suspect additional 55/55M's will come on the market this winter. Earlier this year there were 3 or 4 listed for sale at the same time. There was one in western TN that I was interested in, but it sold before I was able to get out and take a look. Good luck.

The interest started in music, ballet, figure skating, and flying for the Navy. But I did own a long wing for ten years, and she was my love. Like skating, all acro routines start with 100 and lose points there after. We all strive for 100, but how can we measure it from the ground? The ideal is a machine that combines power, agility, and gives the pilot the possibility of adding grace to achieve winning scores, no? But grace is subjective, and scores are not. Having owned a 55, I have known the grace, and traced the accuracy possible via smoke, of what they can do. I know a 55m or a Su26 have their own. They support support faster everything, and that may be important. But I fear that scores have become primary, and worry that grace has suffered. For people that attend ballet, the analogy is clear. Imagine a brick, a flying brick. Something with remarkable spin, climb characteristics. Something that could trace out Aresti curves in 3D with complete fidelity. Is that what we want to pilot? The community sets categories, sportsman, intermediate, etc., but i don't know if it is possible to include the subjective into the categorization process. Fencing, saber fencing, has also endured a debate between form and scores. I left that scene years ago and don't know the outcome, but the argument is similar in that some things score, but are ugly. Who can judge ugly, yet we recognize it when we see it. I suspect the future of aerobatics lies in the use of drones to show what happens when a pilot and his mount, are one. Besides the tracing of 3D curves, future scoring systems may also include a factor for artistry or whatever. None of these ramblings are new ... So back to the issue, and thank you for allowing the preceding digression: Know what your machine can do - and design your program accordingly ... For me, the ballet capabilities of my 55 outweighed the scoring potential of other machines. She still is in my dreams! Best wishes for straight lines, and calm winds.
