with a supercharger attached, we ll be looking at 210hp in the least.You are expecting 220+ knots on 165 HP. That's ambitious to put it lightly. Can you think of any other tube and fabric airplanes that will perform like that?
Concerning the tapered wing - in what context do you assign the term "efficient"? Strength to weight, lift to drag, control harmony... Whats your baseline for reference?
You really have a point concerning the ply wood. I know it needs specific layers. I have some foreign plywood that meets the requirement. still experimenting with the wood strips.No and never was meant to. I think the love of climb was the incentive. I think it made it a porky plane. I’m a Phil Kraft fan. I was not happy when I heard it had been chopped into
I would love and build an improved SuperFli mostly better ailerons. Wing seems to be a lot like a One design and Rihn knew some about it.
Without just being dedicated speed plane, over 220 is really pushing speed for a conventional build it yourself regular airplane. 170 is probably closer to reality. Anyone want a canard cheap in Georgia? Proof its easy.
Wood, the kind used in aviation, is hard to find in Africa. Same with the plywood. I would think building something like a Sonerai 2 would be more in line with what you can get your hands on to build with. Aluminum wing, tube fuselage. Pretty fast in a reasonable way. I think that is a realistic plane to build without shipping expensive materials halfway across the world.
Late 70's I worked part time at a Kraft service center. However about the only thing left of Phil's design in todays radios is the pulse width still controls servo position. And I'm not sure Phil actually designed that but simply borrowed the concept. However in the day his radios were hands down the best. Today's radios are so computerized you'll never really know just what you have. And configuration errors seem to be the crash of choice anymore.You can search on how the big one flies on RC Universe. One of Phil Krafts flying buddies would fly airshows in it. The ailerons were pretty heavy. It’s still around but I think someone put a 540 in it. Phil kept the N number. If you fly RC, his radio protocol is what you fly today.
To start, if you'd like to let go of one of the signature sets?I have a half Dozen Kraft radios including two Signature although not originally mine. I still have an Ugly Stick set up with one for fun. Kraft had the right buddies who designed the “new” stuff. It’s all documented; Bell lab transistors before most knew what to do with them. Now days I just fight the programming to get it to work. No electronics fun anymore. Still to have anything last this long means it was done right.
There are line drawings of the Super Fli. Tube positions and general wing layout, but no dimensions, so it would still be a job to work out.
My first proportional radios were the Blue Max kit radios. Forget who made the kit but it wasn't Heathkit. All components had to be soldered to the boards to include the servos. They were my introduction to electronics. But low and behold, they both worked and for the time, worked well. No doubt those radios influenced my working career in radio systems and computer networks. So in a sense one could say, they paid the bills.I have a Concept Models 40 size in the box. One signature is a 76 and one is a 78 I think. Surprising how different they are with improvements. I got a dial a crash too. Sold a Z years ago which I wish I had to put modern stuff in it and not feel bad, although it should have all been sold a few years ago when people were hungry for them. They are much nicer to hold than the new stuff to me.
