Pete Brautigam's KR2S was finished in 2006, and has several improvements to the design that were common to that period, such as the wings use one of the "new" KR airfoils, the AS5046. He also extended the rudder and vertical stabilizer a few inches, and did the same with the horizontal stabilzer and elevator (which also has small "horns"). Given these changes, I suspect that the plane is widened a bit at the cockpit, as most other folks were doing at the time (and still are), but maybe not. It has the small KR flaps per the plans, manually deployed by a lever, as well as a belly board to really slow the plane down when landing. The paint job looks pretty good to me also. It has basic flight instruments (round gauges), a Grand Rapids EIS engine monitoring system, but no GPS or other electronics, no radio (he used a hand-held) and no transponder. It does, however, have a large space in the middle of the panel for whatever electronics you'd like to add. It has a 12 gallon header tank, and a wing tank in each wing that hold five gallons each, for a total of 22 gallons. The canopy looks like a Rand Robinson or Dragonfly, with a slight tint to it. I believe the "642" numbers are vinyl, and easily removed, if desired. Obviously, it has navigation lights.
The plane has a 2700cc (stock displacement) reverse rotation Corvair engine (total time about 120 hours since major overhaul) with a Sport Performance Aviation front bearing, and dual electronic ignition (William Wynne dual point distributor and coil splitter). There appears to be a problem with the cam gear. Jeff said it started running a bit rough, and while changing the oil, found aluminum flecks in the oil. So he dumped the oil, ran it, and drained it, and still more flecks. This indicates that the aluminum cam gear may have been compromised by the crank gear flexing into it prior to installation of the front bearing, and should be replaced before flying it again. Both Mark Jones and Joe Horton had cam gear failures in flight before the addition of their front bearings, so there's your warning. I should add that Pete adamently states there's nothing wrong with the engine, if you'd rather operate on that assumption, but I'm reporting the "potential" issue in the interest of full disclosure. The wings are currently removed for storage.
Jeff also says the starter mount needs reinforcing, as sometimes it gets out of alignment and has to be tweaked before it'll start. That's something to be done while the engine is being repaired. There's also an issue with a fuel leak near the pilot that only happens during a high-speed pass, which needs to be investigated and repaired ASAP, but may have to be flown to troubleshoot....or simply avoid high speed passes down the runway.
Personally, If I didn't already own two KRs, I would have bought it, simply because I'd really like another KR2S, and I know exactly how to fix it (a new cam gear from Clark's Corvair). I'd magnaflux the crank also to check for cracks. We have a local shop that can do that for pretty cheap, if somebody needs the address. Corvairs are very simple to work on, far simpler than the ubiquitous Type 1 VW air-cooled engine, despite having 6 cylinders. But the last thing I need is another airplane in my hangar, already having three, along with several cars wedged in there with them.
See a video of Jeff Lang flying and landing Pete's plane at Pete's plane flying video, which also shows the panel and plane's interior.
Again, it's sold already, but somebody asked about transport and pickup, and I wrote to him the following:
When I need to transport mine, I put the wings in the back of my little Ford Ranger with them wrapped in a blanket and some foam between them. If you want to make some cradles though, there are templates available for the various sections at the bottom of AS504x templates for free download....you'd want the AS5046 templates for his plane. Kinkos can print them. Wings are four feet wide and about 7' long each. Total length counting spinner is about 16', but the tail can hang off the trailer (I've seen many going down the interstate that way). Width between the outer edges of the spars is 87", counting the wing attach fittings. Distance between main tire centerlines is 72", assuming he put the gear brackets where the plans say to put them. Some folks add wooden extensions to the trailer for the wheels to rest on, depending on trailer width, and chocked, of course. I'm sure you'd have at least a month to pick it up.
