Generally I’m at 62% and 600 mmHg when I fly form with the YAK52’s and Housia CJ’s.  The my M-14 does not really like that.

Really?  When was that?   I have a 1974 Yak   50 sitting here in my hangar.  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.

Back when I had the 260 in my CJ there were only 52s on this   sweet earth.  The Bear 360 is an aborigine- only one.  What is the   Vne of the 50?

Yeah, the thing uses a jack screw to rotate the gear when retracted or

extending.

 There is a guyin the DC area who is building/designing an 80% scale F4U.

He actually reverse engineered the landing gear including the contraction

and rotation.  he spoke at our local EAA meeting.  Nice job from what I've

seen.

It also compresses the gear strut so that it fits  in the wing.

For the sake of future historical accuracy, there is no such thing has R.     

   

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.

Roger that. 



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?

Hmmm. My SU26 cruises with 82% rpm and max manifold pressure at 186 mph corrected for standard conditions at sea level.  Max power 99%rpm gives 205mph in same conditions. 

It is stock with the slowest 260cm air show prop.  I was faster by 5mph with 250cm. Blades

Yes as my 50 but with those pea size fuel tanks cross country is like a

freeking frog hopping across the shoreline.

I lose three mph with my 35 gallon belly tank but then limited to 5g.  But then, I might be tempted to defect.

What does that give you for total usable fuel with the 35 gal centerline

tank? With the internal Aux tank, I have 33 gal.

I think that the first Yak 50's only left the former communist blok in the

eighties. It was Richard Goode who managed to buy the first Yak 50's from

East Germany. 

(Richard, if you read this, is this correct?).
