    Hi Roger, Ive flown a Kitfox Model 1 for thirteen years, am an EAA Flight Advisor. The usual recommendation is to fly your approach at Vso times 1.3, where Vso is your stall speed (with flaps set to landing position). My Kitfox has a Vso of about 33 mph. That would make my approach speed 1.3 x 33, or 43 mph. Not coincidentally, thats also about my best glide speed. But I dont fly the pattern or approach that slowly please read on. First, why is Vso x 1.3 recommended? One reason is because it is very close to the best glide speed in case of engine failure. Another reason is because its the slowest youd want to go around the pattern, giving a somewhat safe margin from stall during a 30-degree bank. Also, maintaining Vso x 1.3 is important for aircraft that fly fairly fast so that a lot of deceleration is not required over the runway limiting the approach speed to Vso x 1.3 plus a gust-margin is important for aircraft that tend to use a good portion of the runway on landing. Keep in mind that Vso changes with landing weight and density altitude. That having been said, theres NO way Id fly my Kitfox around the pattern as slow as 43 mph.or even 53 mph. First, I dont want to grow old in the pattern. Second, I dont want to be an impediment to other aircraft behind me. However, its more than just a kind consideration to fellow aviators being really slow in the pattern is an actual safety issue. For that reason, my target pattern speed is 70 mph. I keep that speed all the way down until I begin the flare. Yes, I float a little. If Im going into a very short field, I modify my usual approach to fly as low as 43 mph on final plus an optional gust-margin. Even in that case, however, I would still tend to use 43 only after base leg because theres no real advantage to fly slower until then. Even airliners fly faster speeds on approach than on final, decelerating in the pattern. I have qualms about flying the pattern and early approach at 70. Another nice thing about a Kitfox is that it slips so nicely to burn off altitude and airspeed. I tend to fly a little high and a little fast. That way, if I have an engine failure in the pattern, I can glide to the field. I do my final aiming adjustments by slipping or by throttle. If you dont slip often, you might give it a try. Its not only a good thing to learn but it can be fun. And using slips can control your landing spot very accurately. If youre not interested in using slips, then you can still fly at say 70 around the pattern and just learn the best way to decelerate on short final by using throttle. My thought is to find a comfortable speed you like for flying the pattern and then decelerate on short final. It just makes sense for slow-flying aircraft.

Hi Leon, Sorry you didn't get any replies on this. I wasn't the builder of my wings, but I know the backing strips are separated at the rear spar. My strip goes to the TE as I'm not a speedster.

    Since we are making conversation on flying patterns, mine are what I think is necessary at the time I'm flying, meaning, if there is traffic, I'll either speed up or slow down depending. If I have to delay my down wind, I'll go to 55 and as soon as I am ready for my base, I pull up just a little and slow to 50, then, now this is really fun, I put in full rudder to the direction I'm turning and aileron and down elevator. I leterally rotate in place, very cool. If I need to speed it up I'll hit full bull and do around 120 in the downwind and base and final is around 80 with bleeding off and a major slip in the process, generally a base to final will be over the numbers about 10 ft. off very cool fun and takes the, crap this is boring, out of flying. As far as the engine out logic, this is mine, if the engine isn't up to par don't take off. Must be why I have a Rotax 912. Have a nice day and above all, make the flying fun. -------- kitfoxmike model IV, 1200 speedster 912ul building RV7a slowbuild wings, fuse Do not archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=117295#117295

    Hey Guy, thanks for the reply.I to have a backing strip on the inboard side of the last rib because the manual is combined for the standard 4 and speedster and they have you install it in one section,ans the in the options section (speedster wing tips) the have you install a 1" backing strip on the outboard side of the last rib.And the backing strips are also there for the flaperon bracket.If I were to extend the 1" strip to the end I think the rivets may interfer with the flaperon bracket install.--Leon---Leon Morris/Classic 4 Sptr/50%/Flower Mound,Tx ---- Guy Buchanan <bnn@nethere.com> wrote: > > At 08:00 AM 6/7/2007, you wrote: > >Hey Don, not to change the subject but did you build your model 4 > >speedster and if so how did you install the 1" backing strip for the > >wing tips?

Kitfoxmike, You have obviously never had a perfectly good running engine quit on you. I don't care what you are running, you had better be prepared for it to happen at the least opportune time. It can and will if you fly long enough. It's a scary feeling yet very comforting to know that you can "make the field" when it does happen. Andy Fultz

[color=darkblue][/color] I had a 032 quit on me on take off... run up was fine etc.. your logic does not work in the real world.. I am not sure I have ever met a pilot that knew his engine was not running right, did nothing to fix it and took off anyway just hoping it would make it another turn around the pattern. hmm.. why dont you do a quick NTSB search and then tell me you dont have to worry about an engine out just because you have a 912... -------- Leonard Perry Soldotna AK Avid &quot;C&quot; / Mk IV 582 IVO IFA Full Lotus 1260 95% complete Read this topic online here: http://forums.matronics.com/viewtopic.php?p=117371#117371

    Sorry guys, I don't understand your logic that you fly a certain way for in case your engine quits. Yup if mine quit I will fly the damn thing down and land it somewhere, right into somebodies driveway if I have to. If I'm flying over water, no brainer I fly it down to the water and steer it right into the shore and up and into somebodies front yard, but I'll be damned if I'm going to fly every second of the airplane worrien about the engine quiting. I'll fly it to the ground and if there is no airport or I can't make the airport I'll fly it down and land it somehow. so there. Sure I've had my engine quit on take off, and landed just fine. Do I need to squirm and worry about it in the future, nope, I'll worry about it when It happens. When it quits and I'm 20 ft off the ground, well at least I know the terrain and I can quickly find a place to land it. Lastly, when it's my time to go, there is nothing I can do about it. Lastly, part two, I'll will never fly a two stroke. sorry again. -------- kitfoxmike model IV, 1200 speedster 912ul building RV7a slowbuild wings, fuse Do not archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=117389#117389

    Saying you will never fly a 2 stroke is your perogotive . I love my 2 stroike light weight and flies great . I just flew over Cook Inlet Alaska with a 2 stroke 582 and never even thought about it quitting . Have you ever read how many lycoming's and continental's quit every year in flight . Go fly your 912 and have fun .

    ok mike I can now understand what you were intending to say.. I too have had an engine out on takeoff (certified 4 stroke).. it did not end as well as yours.. but I still dont fly like it is gonna quit evey second of the flight. -------- Leonard Perry Soldotna AK Avid &quot;C&quot; / Mk IV 582 IVO IFA Full Lotus 1260 95% complete Read this topic online here: http://forums.matronics.com/viewtopic.php?p=117406#117406

    Leon, OK, here is the way my speedster tip are riveted. >From the trailing edge forward, the first rivet on the top side is exactly 3 1/2 inchs. This puts it pretty close to even with the third rivet in the flaperon bracket....not quite..maybe 1/2 a rivet off On the bottom, the first rivet is 3 inchs forward of the trailing edge. So obviously there is a backing strip aft of the flaperon bracket. Top and bottom. I might add that the edge of the fiberglass wingtip fits up right next to the flaperon bracket. It would take a feeler gage to see if there is clearance. Hope this helps you! -------- Don G.

    The main point of all of this discussion is on to worry about an engine quitting but to be prepared to deal with it when it does. While there are areas where there is just no place to land but most of time the pilots just forgets to fly the airplane. -----Original Message----- From: owner-kitfox-list-server@matronics.com [mailto:owner-kitfox-list-server@matronics.com] On Behalf Of eskflyer Sent: Friday, June 08, 2007 8:01 PM Subject: Kitfox-List: Re: engine out logic ??

There is an interesting story about China Airlines, an Airbus 380 and a seat belt in Germany! It needed three new engines before it was given clearance to take off. Two of the three were more or less running. The third one had the seatbelt tied through the front turbine.
