That link was a bit off. Folks, A good friend of mine has done a fantastic job of a stunning profile of the Yak-50 and has begun work on the Yak-52. He will also be doing the CJ-6 in the near future. He is now accepting custom orders for a profile of the Yak-50 and Yak-52. The work really is great! Are you thinking of a new paint scheme for your airplane and not sure what it will look like in the end? Try Barry's work and you will KNOW exactly what it will look like! Check out the Yak-50 he has done (This is Mark Schrick's BEAUTIFUL airplane) http://community.webshots.com/user/junglejett Now, if you want to see what kind of work he does as well, check out his site. He also builds some really cool websites! If you are looking for something different for your business or something personal, drop him a line. Tell him I sent you! (I am not taking a single dime from this, just want to see his work appreciated) Check out his cartoons!! (He is doing one for me) He really digs the Yak!!! http://cincinnatiwarbirds.org/ http://www.spanishcastle.com/justplanefun/ http://www.chuckyeager.com/specialfeatures.htm (checkout the animated series..that is Barry's work) Drop Barry a note at: barry@spanishcastle.com Thanks, Tim Gagnon Yak-50 N359FG www.redstarforum.com ________________________________ Message 2 _____________________________________ Time: 06:59:40 AM PST US From: MFilucci@aol.com Subject: Yak-List: conversion table --> Yak-List message posted by: MFilucci@aol.com If anyone has a conversion table for manifold pressure, mm Hg to inches/ inches to mm Hg, please send the file to me off list at: mfilucci@aol.com Thanks, Mike ________________________________ Message 3 _____________________________________ Time: 10:12:32 AM PST US From: "Richard Goode" Subject: Yak-List: Complaining about Avgas at US$3.42 a gallon! --> Yak-List message posted by: "Richard Goode" Well, at our local airfield Avgas is now US$8.70 - and that is for a US gallon, not the proper imperial one!

NEEDLESS to say I immediately landed and began trouble shooting for leaks in the exhaust. Using shop air I pressurised the manifolds and soap checked the joints, found two massive leaks, one at the joint between #2 and #3 cyl. the other at the point the smoke nozzle was attached to the manifold (if your system was installed by Crowder I recommend you check for leaks). One relatively small leak at the #3 attach spanner nut. I buttoned it back up this morning and flew with the following results: Cruise- 0ppm, 100mph canopy closed - 22pm, 100mph canopy at first notch--0ppm. Hard left turn - 27ppm hard right turn- 22ppm. 120mph smoke on- 12ppm canopy open- 10ppm canopy closed. I believe the remainder is coming from the exhaust pipe exit. ANYWAY You guys may have saved a life!!! I still would like to get it to zero in all regimes, has anyone tried vortex destroyers in the area between the cowl and the leading edge of the wing?

Contact Radial Engine Exhausts in Jumping Branch Virginia their Stainless system uses slip joints not the junk joints of the Chinese system or Russian system. Since it is made from a material superior to the original exhaust systems it doesn't burn through.

I would respectfully submit that the slip joint system will look better and take less maintenance, but to expect a metal against metal slip joint with no seal to not leak under pressure and do anything but get looser and leak more and more over time is in my opinion a great leap of faith. I honestly feel that the properly maintained stock system, be it yak or CJ is still the best way to prevent exhaust leaks in the engine compartment. Back when these slip joint systems were introduced we were not smart enough to consider the gas problem and so there was no worry about CO2, they were not designed to prevent CO2, they were designed to stop the continual maintenance of the seals, clamps, and gaskets and the burn out problems of the standard steel Nanchang systems, and the crack out problems of the titanium Yak systems. "your mileage may vary".

Contact Radial Engine Exhausts in Jumping Branch Virginia their Stainless system uses slip joints not the junk joints of the Chinese system or Russian system. Since it is made from a material superior to the original exhaust systems it doesn't burn through. > > Frank > CJ6-A N23021 > > ________________________________ Message 30 ____________________________________ Time: 05:58:34 PM PST US From: Ernest Martinez Subject: Re: Yak-List: yak list: CO in the cockpit --> Yak-List message posted by: Ernest Martinez Honestly Doug, My short answer is yes, after putting several hundred hours on my system, the joints actually sealed themselves. Firstly they were a very tight fit to start with, secondly over time, the joints fill in with whatever soot may have penetrated through. Many Spam cans and American warbirds have been using slip joints for years. When designed properly they work great. And you said it your self "A properly MAINTAINED" shim and gasket system. The shims and gaskets require maintenance, can move, disintegrate, all situations that will cause an exhaust leak, while a "properly fitted" slip joint system is virtually maintenance free, except for checking the tightness of the head collars which would have to be done on either system. I personally hated the shim/gasket/clamp system. I'm willing to bet that a large percentage of the systems out there are missing the shims and are just relying on the clamps. Its all mooot however since you cant get the slip joint system from Jumping Branch any more anyway, so anyone looking to switch is better off with Dougs stainless system rather than the crappy original stuff that came with the stock engines. Also, I'm not too worried about the Carbon Dioxide (CO2) coming into my plane, but the Carbon Monoxide (CO) :) (Couldnt resist.)

I saw the 34.5 on the task card, and assumed it was a MM measurement but it I wasn't completely sure...was hoping there was a torque... I'll get out my trusty 'ole MM-meter.

Frank CJ6-A N23021 ________________________________ Message 34 ____________________________________ Time: 11:57:31 PM PST US From: "Frank Stelwagon" Subject: Yak-List: Stainless Exhaust --> Yak-List message posted by: "Frank Stelwagon" You are right the gentleman in Jumping Branch, Virginia did sell out, however the company that bought him out didn't want anything to do with radial engines and last I heard he was still in business making radial exhausts. As Doug Sap said he has Chinese Stainless systems for sale also. Regarding slip joint leakage, there are a large number of turbocharged aircraft running with slip joint systems ahead of the turbo, they hold up real well as leakage kills the turbo system. No exhaust system is maintenance free and should be watched carefully. Longer exhaust outlets? Will they clear the lower cowl on the CJ? Frank CJ6-A N23021
