The empty weight on my Series 5 is 800 (798). Yeah, it could probably be lighter and fly much better. However I think that there is a point where you sacrifice some utility and comfort. For me, my Kitfox is a perfect combination of performance, utility, looks, and comfort. One of the things I liked most about this kitfox I bought is the full lexan doors. They bubble out, so I have awesome visibility and it also adds to the roominess. Most of the kits now incorporate that into them so that is not a Kitfox only benefit. The performance is far more than I expected from this little airframe. It will fly backcountry with little trouble. It will pack a load with little complaint. It will fly fast enough to piss off some SC fliers. And it will do all that while burning less fuel than most people out there. That fuel burn is part of the performance for me. I am very happy with what I got.
I agree with the flaperons point of view that Hotrod150 brought up... well, at least I did. I was really looking at the Highlander for that very reason alone (I personally like the look of separate flaps and ailerons). I also liked the openess of the cargo area on the Highlander. But that's another subject. Back to the flaperons: I really like how they set up the flaperons on the Series 5 on up. They are very effective. I use the flaps for takeoff and landing. First notch helps get the tail up around 20. Second notch gets me in the air around 35. I use full flaps for most landings now so that I have the best visibility while landing. I used to always land 3 point, but now prefer wheel landings. But that's another subject. The aileron part of the flaperons are great especially while you are low and slow since they are separated from the main wing. This keeps them in less turbulent air. Even while full flap, they work great at slow speeds. I usually come in around 45 if I want things tight and set down right at 40. I have complete control right up to that point. My Series 5 is fully stock (ie. no VG's etc.). So I would say that I really like the flaperons now. I wonder how much faster I could fly if they were tucked back up in the wing, the prop pitched for cruise, and the wheel pants it came with installed. However, all I ever really wanted was a 100 mph bushplane that I could afford. I always see 110 mph (96 knots) with 8.00 tires so I am happy with that. I also wonder how slow I could get with a VG kit like what the Highlander comes with.
I have flown with a Zenair, various Super Cubs, and a Skylane. They all fly differently than my airplane. I was able to keep up with all of them for the most part (the skylane of course throttled back - but he is a good friend of mine). Most took off like me, but most didn't climb like me. Most were a little slower than me, but everyone burnt more fuel than me. But that's just my experience. I hope I'm not too biased... I'm sure there are plenty of airplanes that can post better numbers. Frankly speaking, that's great to hear. I hope we can keep innovating and impoving to see what is possible. Until that perfect airplane, I'll keep enjoying my airplane because that's what I've got and it works great for me.
Flying is magic... till you hit the trees.
