Glen,

Take lots of digital pictures before removing anything. I did this when I removed and replaced the motor on my CJ and they were invaluable.

I thought it was you end cap for the tail wheel shock absorber that you had to have a new end cap machined for? My question is how is it holding up mating stainless steel to aluminum threads on the shock absorber body?

But, you should remember that when in flight the cockpit is already lower in pressure than is the air and gasses flowing over the fuse and canopies. By opening the panel you will lower the pressure in the cockpit even more, which will draw in even more gasses. The only way IMHO to beat the problem of gasses in the cockpit, and yes this horse has been whipped to death already, is to pressurize the cockpit to a pressure equal to or exceeding the outside pressure. Yes, you could open the vents and crack the canopy a bit to "air wash" the pilots with blast air, this works to a degree,(pun intended) but is not a healthy alternative up here in the frozen north. I think the installation of a good exhaust system which incorporates a cabin heater with the option of heated air or unheated blast air is the only civilized way to solve the problem. The Yak 52, Yak 18T, or perhaps some of the newer slip joint stainless steel systems have this option. The Yak 18T system is in my mind the best option, as it fits the CJ6 lower cowl cut outs perfectly. The Yak 52 system while it has basically the same heater as a Yak 18T system will not align properly with the existing "exhaust out" holes in the lower cowl, causing a huge butcher job to move the holes to the proper location. The Yak 52 or the Yak 18T section which contains the cabin heater can be modified to fit the 285 hp system by changing the exhaust nut and rewelding the exit pipe to the proper angle, not easy but it can be done.

From: "Genzlinger, Reade" OK - you guys jinxed me - all this talk about generators has done me in. I go to fly the Wilga yesterday - first time in ages - she fires up - good, go to warm up speed and generator comes on line - good, taxi around and go to low idle - generator goes offline - good, bring rpm back up and oops - no generator! Go low idle and back to high idle - nothing. Reset generator switch - nothing. Cycle overvoltage protection - nothing. Cycle low voltage circuit - nothing. Shut down/restart - no change. So, now I get to do the generator trouble shoot thing and I hope I have what I need in the spares kits. Can't change out the generator - it's licensed in the normal category so I don't think I can go the alternator route (i.e. no approved alternators for this application). And it was the first nice day in ages - oh well.... BTW - after reading the hours of stuff you guys put out I believe I'm ready for the generator/alternator CEU test. How much credit is it worth? Signed, I like fixing most everything except the stuff with wires.

I do not know much about the Wilga but does it have a power distribution panel? Does it have BNP 200? Where are your Russian fuses mounted. I would take them out of the circuit and ohm them out. Particularly the 30 amp fuse inline with the carbon pile regulator and the BNP 200. Mark B+9 can help with this one a bunch. He helped me.

A of yesterday there are 45 CJ-6 signed up for the 50th anniversary of the CJ-6 at OSH this year. Of these 33 are rated FAST pilots and 13 who say they are not rated.. There are 13 Yak aircraft signed up. 8 are flown by FAST rated pilots. I've heard from a number of folks out there they and others are planning to come but have not signed up yet. It would be real great and more accurate if those folks would go ahead sign up so we can plan on what we'll need. A number of sponsors are furnishing funds that will pay for a lot fun things we'll be giving away. Some of these are so unique that you will never be able to get them anywhere unless you attend and participate in this celebration. Like a coin minted only for this event, that will show only one number that will indicate your position in the mass formation during the show. So guys go to the RPA web site and sign up.
