Mark did a flawless job on the build of your machine. I sure would like to have your Kolbra in our Booth in Oshkosh this year. The Kolbra is a nice design with lots of room in the rear.

Thanks for posting. Again, your audio quality is outstanding. I noticed in the first video you were cruising at 90 mph IAS but did not see what RPM the 912 was turning. What RPM gives you that IAS, and is your IAS fairly accurate? FWIW: I cruise most of the time in my Slingshot at 85 mph IAS (which equals TAS at about 2000' density altitude) to keep the noise down to a tolerable level. That is at about 2750 rpm on the Jab 2200 (3300 rpm is redline). 2750 rpm direct drive with 64" prop gives about 600 mph tip speed, which is noisy enough. -------- Thom Riddle Buffalo, NY (9G0) Kolb Slingshot SS-021 Jabiru 2200A #1574 Tennessee Prop 64x32 Don't accept your dog's admiration as conclusive evidence that you are wonderful.

When I posted a view of the panel, questions arise. After I bought the Kolbra, I thought the ASI read a little high and found it actually read 10mph higher than it should. I got used to flying it that way and never tried to recalibrate it. The cruise is actually 80mph and not 90mph as it indicated. I wish it was 90mph. If I installed a 100hp 912, maybe it would approach that speed. I will have to look over John Williamson's Kolbra specs as he did have the 100hp 912 and our planes were identical in function.

I will have to look over John Williamson's Kolbra specs as he did have the 100hp 912 and our planes were identical in function. Ralph B Ralph B: John W's Kolbra cruised at 80 kts (92 mph). Max speed was 90 kts (104 mph). When we flew cross country together, John W would have to slow down to my cruise speed of 70 - 75 kts (80 - 85 mph). Generally, John W was 10 mph faster than me across the board. When he was flying with the Jabiru, our cruise speeds were the same, but there was no comparison between take off and climb performance. Don't remember what prop John W used with the Jabiru, but he flew with a 68" three blade fast taper Warp Drive on the 912ULS. john h mkIII Titus, Alabama ________________________________ Message 7 _____________________________________ Time: 10:49:27 AM PST US Subject: Kolb-List: FSII wing, tail, BRS for sale From: "Richard Pike" Time to clean out the hangar, got a left wing in repairable condition, a set of horizontal stab and elevators already covered, in excellent shape. Have a vertical fin and rudder that can be repaired, will need recovering. The BRS is out of date, but otherwise in good shape. Make an offer on some or all, can ship the BRS, the rest of it is cash and carry.

It may be a little slower in speed, but on a 500 mile trip it would only save 42 minutes of time. I would spend the time saved pumping more gas into the tank and making more fuel stops, so would it really save any time? Something to think about.

Ralph Ralph: Normally, the 912UL burns 4.0 gph at 5,000 rpm (normal cruise rpm for most of us). If you are only burning 3.5 gph you must be turning the 912UL slower than 5,000 rpm. I think you have the best combination with the Kolbra and the 912UL. You get better fuel economy, more time out of spark plugs, and can burn 87 octane auto fuel. My first 912 series engine was a 80 horse I installed in 1994. It was a good engine. Made my flight around the country and up to Alaska with it the two months after I installed it. john h mkIII Titus, Alabama ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message kolb-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Kolb-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/kolb-list Browse Digests http://www.matronics.com/digest/kolb-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
