KR> Wrecked KR2 in Des Moines IA
>Not my airplane...I know nothing about it... Just passing on the? info.. >http://desmoines.craigslist.org/for/5052761019.html The airplane was registered Feb 1993 and de-registered in Aug 1993. Belonged to a guy in Waterloo and now is in Des Moines a 100 miles away. I was not aware of the KR even though I live and fly in the area and was active in the EAA at that time. I can check it out if someone is interested. Brant Hollensbe West Des Moines

KR> Jabiru 2200 vs VW
Mark, Unless you have serious rabbit foot collection, leave the Corvairs in the garage! Nobody can keep surviving crank failures at low altitude . We all want to keep you around for many years to come! Cheers Chris G.

> My bone-stock KR2 with a 75 hp VW 2180 burns 4.0 US gph (3.33 UK gph) at 148 mph, throttled back a bit to conserve fuel, turning 3150 rpm" My bone-stock KR-1? gets almost exactly those same numbers. WOT 3.9 GPH 148 MPH at 10K and above. I run as lean as the engine will let me (in cruise - not in climb where the excess fuel is needed for cooling) which is to say, as lean as I possibly can. I've got a huge amount of cooling drag I've never gotten around to doing anything about. My air inlets are the standard size they used to build them back in the 80's. Way too big. Richard Shirley's are more like what they should look like. Mike KSEE Old School Yearbook Pics View Class Yearbooks Online Free. Search by School & Year.

KR> 200 mph cruise KR2!
The standard Jab configuration uses a Bing altitude compensating carb with no mixture control. I'm used to litres in this part of the world, but I know the J160 (same engine) at my local club is documented as burning 18 litres per hour (4.7 US gal per hour) for flight planning purposes. On that basis 7 gph could be in the ballpark for takeoff power.

KR> 200 mph cruise KR2!
I can speak to this, owning a Jabiru and having flown it coast to coast. The Jabiru has a bing carb, which is altitude compensating with no mixture control in the cockpit. It uses a tapered draw-needle for metering. The taper on this needle has been modified by jabiru over time. Early ones provided very rich mixture at full throttle for take-off to prevent detonation. The extra-rich region has been toned down over time as, reportedly, was deemed safe. But yes the stock Jab carb goes rich at WOT. Come back just off WOT and you get normal EGT's. I burned just over 5GPH using high cruise throttle settings and the old style needle (and was going 100MPH, the Avid is a draggy airplane). Others in my user group see under well under 4GPH in cruise. Now, if I left it at WOT and looked at fuel flow, could that extra rich region use 7GPH? I would say that is not impossible at all, but never measured it as I dont have a fuel totalizer unit. > CC: ml at n56ml.com > > Colin Hales wrote: > > >>My 75 hp 2.2 Jabiru Powered KR2 does 148 mph flat out burning shed > loads of fuel. 7 Gallons an hour. << > > Don't Jabirus have a mixture control?
