Does anyone have advice on >installation, operation of these units in context of Rotax 582-90 fuel system? I can't help you with the Facet pump, but I use the HACman and like it. I installed it per the instructions with few modifications and it works well. I exchanged their awful black tube wrapping for a plastic braided sock that looked a lot nicer. I also used an EPM.AV firewall fitting with a long piece of fire-sleeve on the firewall side to help preclude an engine fire entering the cabin after melting the vent tubing. The only thing I can add that's not in the instructions is that when I'm flying I typically go full rich before any significant descent. I then descend at the angle I want and set the RPM's for 5800. I vary the angle of descent and RPM to get an EGT of 1200. If I get too steep, the EGT gets too high, even at 5800 RPM, (over-driving the engine,) so I pull it up, (slow down,) until the EGT's get back below 1200. (My EIS gives me a warning at 1200 so the EGT's never get over about 1210F.) If I want to descend steeper I drop the RPM way down. (You have to watch the cold seizure then.) > Guy Buchanan K-IV 1200 / 582-C / Warp / 100% done, thanks mostly to Bob Ducar. ________________________________ Message 6 _____________________________________ Time: 10:58:41 AM PST US From: "David Steade" Subject: Re: Kitfox-List: First Flight G-CDXY Michel There is much more inertia with the Mk7 due to the increased weight this makes it more stable. The simplified mixer for the flaperons together with the differential movement results in less rudder input than on the Mk3 and a lot more feel. My Mk3 had a 582 so the increase in power with the 912S is very noticeable with a significant increase in cruise speed and climb rate. There are lots of small changes that have added to the comfort. Good heater, no drafts from the doors, somewhere to put the coat and bags, a bit more width in the cockpit all in all quite a different aircraft. In the UK there is only one other Mk7 flying with two more being built, most of the Kitfox fleet of about 50 aircraft are Mk2 and 3 versions with a handful of Mk1 and 4 and just one Mk5.

They guy can carry the wings under his arms. The only thing is that it can't be registered in Europe as an ultralight aircraft (a paradox, really) because the wings are not very big and his stall speed is over 63 km/h, our definition of the utralight class. Therefore it needs the PPL-A license to fly. Silly, isn't it?

Thanks, David. Of course, one would expect that the aircraft becomes better and better in the later models. Now, I know better how.

My concern is there seemed to be very little, perhaps only one half inch, of clearance between my head and the primary structure directly above. I am 5=928 =BD=92=92 tall (a giant by no means). It seemed like a little turbulence could be a problem with head banging. The gentleman who owns the aircraft is a couple of inches shorter than I, so it could have been a non-issue.

I'm hoping someone will be willing to answer my question about the Kitfox SS fusalog. Is the fuse normalized after welding by the factory? If not why do you think this process is not important to the strength of the structure? I sent this question to the factory and have not received a reply; they must be busy with the move. __________________________________________________ ________________________________ Message 13 ____________________________________ Time: 03:22:47 PM PST US From: "jeff puls" Subject: Re: Kitfox-List: Model 4 headroom clearance John, I am 6'4" and fly a Kitfox Classic IV with Skystar cushions.
