Just thought you guy's might be interested. Ken homepage www.ecofly.de and www.fk-leichtflugzeuge.de In the moment we have flying 12 ultralight aircrafts with the Smart- Engine. The first 60 KW engine has now 65 hours flight time. One 45 KW engine hase more than 1400 hours without any problem. The performance of the 60 KW engine is comperable to the Rotax 912S. Our gear and enginemount is also used in the push-pull unmanned aicraft "Hunter" of the US-Army.Here we work together with Northrop Grumman. The weight of the ready to run Firewall-Forward-Kit without Propeller and without cowling is 86 Kg and the price is 8.800.-EUR. The time of delivery is 6 weaks. ________________________________ Message 2 _____________________________________ Time: 12:08:20 PM PST US From: "Christopher Armstrong" Subject: RE: Kolb-List: German Engine --> Kolb-List message posted by: "Christopher Armstrong" That is interesting From the Smart car web site: The suprex turbo engine. A powerhouse without a single superfluous gramme on the cylinders: The 3-cylinder rear-mounted engine with turbocharger and charge air cooler weighs just 59 kg. That means: ample power, low fuel consumption and low emissions. So the basic engine weights just 139 pounds, his reduction drive, engine mount and other accessories must weight 50 pounds. Not two bad but It sure takes what looks like a good light engine right into the heavy weight category.

Calculations indicate that 50, 55, and 60 mph would be 0.58, 0.78, and 1.01 hp. The hard part was making the fairings for 5/16 OD tubing. How it can be done can be seen at: http://www.thirdshift.com/jack/firefly/firefly105.html The process of mounting, shaping and covering the fairings can be seen at: http://www.thirdshift.com/jack/firefly/firefly106.html Just finished it up today, and took the FireFly for a short spin. It seemed a little quieter. Could not check out speed differences due to turbulent air. Hopefully I will be able to fly to the next EAA 453 Chapter meeting in a couple of weeks. Then I will get speed, fuel consumption, and noise measurements. Have a good weekend. Jack B.

It hardly weighs more than the tubes do. http://www.mindspring.com/~possums/tailmod.jpg http://www.mindspring.com/~possums/ailermod.jpg http://www.mindspring.com/~possums/Xhingestrailingedge.jpg http://www.mindspring.com/~possums/Modtail&swagedwires.jpg At 09:11 PM 4/7/2004, you wrote: >--> Kolb-List message posted by: Jack & Louise Hart > >FireFlyers and Kolbers, > >In my quest to get a little further on five gallons, I have faired in the >trailing tubes on the ailerons, elevators and rudder.
