Date: Mon, 14 Dec 1998 16:55:29 -0600 X-Message-Number: 2 I've purchased a KR-2 without knowing much about them. After flying the bird I noticed that the pitch felt great but the roll rate was really a dog! Does any one know what the roll rate should be. I'll roll my C-150 faster than this thing. Note: it has the Diel wing skins on it. Thanks for any replys Joe ---------------------------------------------------------------------- Subject: Re:Hello I'm New - (to the KR world anyway) From: Robert Covington Date: Mon, 14 Dec 1998 16:35:19 -0700 (MST) X-Message-Number: 3 >I've purchased a KR-2 without knowing much about them.

I gather you like a plane that has "sporty" handling. The plans have the ailerons running almost the full length of the outboard wing. Did the builder of yours make them shorter by any chance? Robert Covington ---------------------------------------------------------------------- Subject: starter\valves???? From: "Jesse Klebsch" Date: Mon, 14 Dec 1998 15:53:04 PST X-Message-Number: 4 I believe I fixed the bad starting problem, the engine had two burnt vavles and I've replaced those and touched up the others- starts much easier, even prop started it a few times. I found a starter that is exactly the same as what was on it. It came off a 1977 Artic Cat 440 snowmobile, same size and number of fields- but an Itachi instead of a Bosch. Works fine for now, but i'll get a new one from great plains in case it snows. The engine runs fine for about 15 seconds at full throttle, then it develops a miss and occasionally back fires. It seems like it is running out of fuel but i've replaced or cleaned and checked everything in the system at least 5 times and that isn't the problem. I was wondering if it wasn't running fine until the lifters were getting pumped up and then they would hold a valve open a little? I talked to steve real quick and tried adjusting them warm (just bring the rockers arms to the valves and no farther) but I still have the problem. I had to put more shims under one side of rocker arms to get the clearance so i could back the rocker arms off the valves. Is this normal? There were already quite a few shims under them- at least an 3/16" high. I plan on leaving everything until the morning so it is absolutely cold and then starting over. If that doesn't work, there is a KR-2 for immediate sale- cheap! :^) or maybe dynamite would fix it........ The school i go to has a four day week, and Thursday is the final day until January 4 (Christmas break) I'm begining to wonder if I should continue to try and make it. At least it's a pilot school, so they understand. Thanks, Jesse Klebsch > >We need to know what kind of fuel system you have to best help you with your >problem, also what kind of ignition.

The best you could do would be to be there for Wed & Thursday. The worst could be that the VW would cough big time (and maybe quit) on climbout. Better to have you on the ground solving the problem rather than reading about your forced landing in the paper. Your life is worth more than a lousy couple of days of school. You can quote me to your teachers too! Again, work out the engine problems to your satisfaction while both feet are firmly on terra firma. Anyone disagree?

Brad had a lifter body failure in his 2100 and it darn near ruined the cases. Good thing he caught it (the noise) before he departed for the day! Allan has nothing but problems with his hydraulic lifters. Seems he gets them set and has great compression all around then after it runs for a little while two cylinders go almost flat! He too has burned a few valves in the past 6 months. This used to happen on Brads machine too until he took the lifters out and threw them in the dumpster at the end of our hanger. Damn that dumpster is handy when you get mad at something! :o) Brad has solid lifters now and his engine is running stronger than ever. Allan is still scratching his head and wants to build a new engine (one without hyd. lifters). Steve, what are your thoughts on hyd. conversions? -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims SP290 (Sky Pig 290) ,..Building Cowling now mailto:mikemims@home.com http://www.geocities.com/CapeCanaveral/Hangar/4136/ Aliso Viejo Ca ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ---------------------------------------------------------------------- Subject: Re: What does yellow tag mean?

Brad had a lifter body failure in his 2100 and it >darn near ruined the cases. >Micheal Mims I have a 2 Liter VW bus with a type 4 engine and hydraulic lifters. I personally would not run hydraulic lifters in a VW airplane engine given my experience with them, and it hasn't been all _that_ troublesome. Problems: They can stick. When I had the engine out of the van for a clutch change after I got the vehicle, one of the lifters decided to freeze, and it got mushroomed by the camshaft, so I was told by the mechanic. Anyway, since the engine was already at 100,000 miles, that precipitated a rebuild. Case had to be split anyway to get that lifter out. I now have 48,000 miles more on that engine, and if the thing sits for a while,and you start it up for a brief period, then shut if off before the lifters pump up, it will make quite a racket upon the next start and sound like it is killing itself until it finally gets that air bubble out of there and pumps up. I just wouldn't want to deal with anything like this in an airplane situation. It may be that the guy installed the lifters in the wrong cylinders during the rebuild though or some other thing. They need to back in the proper spots where they have worn in. The engine backfires on deceleration all the time too, and nothing I have had done to it stops that. :) I don't know if that is due to lifters, Fuel Injection, or other things. But for a car, it is all tolerable. I would prefer to adjust valves every 20 hours in an airplane VW than deal with potential problems with the hydraulic versions, and I really would rather be able to use those!
