How many of you have designed your own models?

Like the title says. A little less intense than the "who has produced their own kits" thread.

Note the bit about plagaizing in the first selection. This is an admission that most of us lean at least a little on what we already know.

There's not many of us that truly step out of line and move off into totally untried territory. There's only a few of them that I can think of and one of the most recent seems to have this thing for the fine arts.... namely dancing.....

Currently doing a complete scratch build from technical drawings. The only thing that I would say is borrowed may be the airfoil design. Other than that it will be completely my own.

Mike, what kind of model is it? And are these YOUR technical drawings?

Always good to hear about people creating something new.

What the heck. Let's get some graphics in here too. Here's a glider design I'm working wtih on and off over the past few months....

At the time of my vote, it's the only entry in the 2nd category. I enlarged a set of plans 200%, changed some outlines to closer match the scale prototype, corrected an obvious error in the cabane strut arrangement, modified many structural details, including reduction of most of the wood sizes by 50%, and changed the power from glow to "E". I still wouldn't call that much change an "own design", but a combination of the designer's ideas and my own preferences and experience. I have been very satisfied with the end result.

BTW, Knight's plane will be a model of a truly Canadian design. I'll let him reveal the name when he's ready, but it's a 'beaut'. There are no flying models kitted for it that I know of, so it's definitely a scratch project, from plans to end result.

I designed one from scratch and buried it 4 seconds into its maiden flight. Needless to say, the engineering skills weren't quite there but hey, it was fun! That whole weight/power ratio was beyond me at the time.

After seeing some of the stuff people here design, I've been inspired to give it another go. Will defiantly get some help this time however.

I guess the nature of this thread is such that you'll get a lot of people posting & voting who have designed their own, which will skew the results.

I've certainly designed my own from blank paper upwards and even had one published, but nowadays mostly build kits due to time pressures. Don't recall ever building a kit fully stock though

BTW I'm not sure about the "plagiarising" bit, are you saying (for example) that any model which has ribs and spars in the wing cannot be considered an "original" design ?!

I always heard that if you copy one person's work, it's plagiarising; if you copy several people's work it's RESEARCH!

I suppose I shouldn't have tossed that bit in but I just couldn't help myself.

Is it plagiarising if you use the happy median for a charactaristic? I guess not. But if you use a wing tip shape that someone else has then it could be. We are all guilty of plagiarising the Schumman tip at least in sketches I would think...

But I personally like to think of it as "inspiration". At least that's my story and I'm sticking with it....

I have designed and flown a few of my own over the years.

Right now I have a 2-metre and 3.2 metre for TD and F3J and a 1.5 metre slope racer all three of which use quadruple taper planform wings.

A wingeron, a couple of flying wings and a Rodent inspired high speed ship, all of which I designed from the ground up.

Making molds and cutting cores, bagging etc. is very time consuming but flying ones own creations is very rewarding.

I now have access to a digital camera and I will post some photos' of my planes in the Gallery.

Here are 3 of my own "design" - a sclae models except the Bandit which is a scaled down BVM Bandit. All construction is self designed.
Very rewarding for me to be able to do this stuff

SAM designs

I only take hand-drawn designs from the '30s and re-create them on AutoCAD so I am not a designer. On ACAD they can be scaled up or down with some alterations to use standard balsa stock and this provides digital info for laser cutting.
There are some stuctural changes to accomodate the new size and movable control surfaces that were not part of the original free flight plane but the appearance will be accurate.
They sure look great sailing around up there!

That's a fine lookin' bird ya got there Donk. But I have to admit you've got me stumped. I don't recognise that one at all. The wing looks quite "Lanzo'ish" but the tail surfaces don't register with any of my grey cells at all. And this is coming from a fairly avid Old Timer.

So 'fess up. What is that?

That (correctly) is a Lanzo Racer of 1936 vintage. My favorite by far. Easy to build and flies so steady, even under high power.
I have designed it and my friend makes a short kit for 280, 660, 800 (mine) square inch versions. The 660 can be used with an Astro .05 motor. I have a 1050 version but we have never kitted it or even plotted it.
The famous Lanzo Bomber came out the same year. You can see the feathers are almost identical. Racer has a slightly higher aspect ratio.

Originally the Racer had a 12 foot wingspan!

That is a lifting tail and the big rudder really has authority.

<slaps heel of hand to forehead>.... Ah, of course! Now I remember. One of my SAM8 flying buddies has a full size copy flying on RC. I've only seen it a couple of times and that was a few years back. That's why it looks so Lanzo'ish......
