(6mm=.236) and (.25=6.35mm). So #4 tubing is a little larger (.014), and the flare is the same angle (real close). You will need to use the AN collars with the AN tube, then drill out the Metric B-nut to accept the AN collar. Now if all things are equal you would be opening the B-nut .014 in diameter. Not enough material to change the strength of the B-nut.

The series began with the Yak-18 with a 5-cylinder engine; which went to the 18U, a nose-wheel version; to the 18A (on which the CJ6 was based), which had a 260hp 9-cylinder. The first pure aerobatic aircraft was the Yak-18P, which was a lightened A, with the pilot sitting where the front seat would be. This was followed by the 18PM where the cockpit (again a single seater was where the rear cockpit would be in the 2-sseater, and a 300-hp engine. Still nose-wheel. Finally (and the one that competed in the 1970's until the Yak-50 was the 18PS, which was visually almost identical to a 50, but with longer wing span.

You do not want to use "aluminum" tube. The Chinese tubing is a high quaility alloy very similar (or likely identical) to AMS 5052. It has a wall thickness of 1 mm (.040"). The replacement must be at least equal in strength which is a function of material specs., diameter and wall thickness. The replacement must therefore be AMS 5052, 1/4" X .049". The generally available 5052 tube is 1/4 X .035. which due to larger dia. and thinner wall does meet the strength requirement. The heavier wall is available a slightly higher cost. Do not even consider using the much cheaper aluminum tubing availabe in coil form. This is,at best, 3000 series and has a strength somewhat better than cheddar cheese. Do yourself a big favour and buy a Parker aviation flaring tool. Walt ----- Original Message ----- From: A.

Just FYI, my YAK-50 came to the United States in the early 90's as well. I would have to check the logs to get the exact date. It had 130 hours on it when I purchased it. No, I do not believe there were any in this country that early either (70's). Ok, how fast will your CJ-6 go with a stock engine at full throttle? Over 200 mph? Not your M-14 model please... The stock version. You are of course correct. Any airplane can go fast in a dive. And some can go a lot faster than others. But I believe my comment was simply that at the YAK-50 Vne speed, the wings would probably come off a CJ-6. Of course, I could be wrong. I honestly have no idea how fast a stock CJ-6 is at full throttle. Would someone please just say what it will do? I've already said my stock YAK-50 will do 200 mph. So, ... How much faster is the CJ-6? If we start talking modifications, then we are entering a whole different category. I know of a few YAK-50's that I would be willing to bet $2000 on going against any CJ-6 out there, modded or not. Jan Mevis, is one of them. Tom Johnson is another. These are not built for speed. They just have really powerful motors and good props. But all that said... I fully believe that as an AIRFRAME, the CJ-6 is better than any YAK or Suke out there for the capability to go fast.

It was only in here a month or so when I bought it. I was not personally aware of a Yak 50 being in country at that time. There may have been one but I willing to bet not before 1972 or 74.

This is the way I have it figured--- the first guy to win will have a automatic opportunity to do it again because the loser will have many ego saving excuses to go do it again, and as we all know and have seen ego overrules good fiscal responsibility every time. So after winning twice a fella can afford to have his motor overhauled (well almost). So you'd better come to grips with the fact that bragging rights are not worth squat, I fully agree with Pappy and would only add that just knowing that a portion of the 50 crisp C notes in my greasy palm actually came from you would be priceless.

Bright Chrome side exhausts OK. JATO bottles - bad sportsmanship. Many years ago, there was a Huosai engined CJ that was really fast. It was stripped to the shell, nothing in the back hole but seat and stick, 300 lbs less than mine. Haven't seen it since. Over the course of several timed races and test runs, I discovered that a CJ-6 needs quite a while to get that last 10 kts.

Just FYI, my YAK-50 came to the United States in the early 90's as well. I would have to check the logs to get the exact date. It had 130 hours on it when I purchased it. No, I do not believe there were any in this country that early either (70's). Ok, how fast will your CJ-6 go with a stock engine at full throttle? Over 200 mph? Not your M-14 model please... The stock version. You are of course correct. Any airplane can go fast in a dive. And some can go a lot faster than others. But I believe my comment was simply that at the YAK-50 Vne speed, the wings would probably come off a CJ-6. Of course, I could be wrong. I honestly have no idea how fast a stock CJ-6 is at full throttle. Would someone please just say what it will do? I've already said my stock YAK-50 will do 200 mph. So, ... How much faster is the CJ-6? If we start talking modifications, then we are entering a whole different category. I know of a few YAK-50's that I would be willing to bet $2000 on going against any CJ-6 out there, modded or not. Jan Mevis, is one of them. Tom Johnson is another. These are not built for speed. They just have really powerful motors and good props. But all that said... I fully believe that as an AIRFRAME, the CJ-6 is better than any YAK or Suke out there for the capability to go fast. Pappy, you have to know the numbers here. What are they?

I saw a (what was than called a "Yak 18R") or Yak-50 at the world acro competition in England in 1972 (or 74?). I believe I still have a 35mm slide of it. My CJ( a 69) came to the US in 94. It was only in here a month or so when I bought it. I was not personally aware of a Yak 50 being in country at that time. There may have been one but I willing to bet not before 1972 or 74. The Vne on the CJ is 217mph. We all know any airplane can go fast in a dive. The race should be about straight and level - full throttle - max RPM. If you want to compete straight off the line plain vanilla examples to me , or stock, would be to me more approbate. The rest is fluff as they say.

You had your stock CJ before then? :-) If equipped with the 500 kmph indicator, the maximum allowed speed (Vne) is 470 kmph, and that translates to just under 300 mph, .... actually 292 mph. That is out of the YAK-50 flight manual. What's the Vne on that CJ-6 Pappy? Anywhere near 300 mph? Just curious. Mark p.s. From the same manual: "At an engine power setting of 99% on a M-14P equipped YAK-50, the 'near the ground' maximum sustained speed is 198 mph. Mine does 200 mph, but hey... I am also turned up a tad over 99%. And.... airspeed indicators can be off just a tiny bit now and then. :-) But over a course averaging both ways, it came out to 201 mph. --- On Fri, 3/26/10, cjpilot710@aol.com wrote: From: cjpilot710@aol.com Subject: Re: Yak-List: Top Dog race To: yak-list@matronics.com Date: Friday, March 26, 2010, 10:39 PM Back when I had the 260 in my CJ there were only 52s on this sweet earth.

The 52 is painfully slow. For some reason, some folks think the 50 and the 52 perform about the same. Did you actually walk right away from a 50 when it was WFO ???
