Default OK .. scratchers ... here's one for you !

Lets take a single sheet of Depron .. standard sheet ... 1.2m long, 0.6m wide.

I'll give you 3 bog standard cheapo 9gr servos.

A typical 24 .. 28 size parkfly motor of 1200 - 1400kv and a 7x6 prop.
25 - 30A ESC

Lipo in the 1000 - 1600 3S range.

Bamboo BBQ sticks and a Parkfly 4ch Rx.

Knock out a simple plan design ... no need to even build - just knock up something to use that lot ... simple and cheap ..

Let's see what you come up with ... and this is the 'kicker' what you expect it to be able to perform like ? !!

I'm holding back my sketches till later ...

Fokker Eindecker. Wood dowel sticks work well for the wing LE and also the overhead structure for the functional wing cables as well as landing gear. Obviously depron sheet lends itself well to the boxy fuselage shape and thin undercambered wing. Did one years ago using depron sheet. The plan would just be a simple 3-view drawing.

Here you Go Nigel Its a Scratch Built Gee Bee it has a 31" W/S, 6 1/2" Wing cord, 23 1/2" long, double the fuselage, use 6mm depron and epoxy it together, the wing is 6mm depron, you can toss some BBQ bamboo in the wing to help stiffen it up a little, it uses a 7x6 prop, 1300 mah 3 cell lipo, 30 amp esc, 1800kv micro motor, 3 - 9 gram servos, the motor has about a 5 degree down thrust, this plane is very very solid in the air, it flies a little like a Spitfire because of the elliptical wing ends, and its Fast, Very Fast, and barrel Rolls like crazy, sorry no video right now of it, 1/4 Throttle is fast on this plane BTW, Please Excuse the RED Thong that I used to hang the plane on the Wall with LOL, Hey, It works

The BBQ skewers also work great as control rods ...

Basically - I am trying to get as many simple designs up - so that those who haven't dabbled in it - can see nothing is hard .. simple works.

There already : WW1 Fokker .. between Wars GeeBee ... what next ?

My current easy 1-sheet build is the FunBat. KFm wing. 2 servos. Super-fast build. Plans from Bloody Mick's.


That's way more motor that I usually run, though.

If I had to pick something a bit more 'plane-like,' I'd build a biplane. Probably a Tiger Moth, cuz I love me some moths. Here's a 26" Moth I made from 1/4" blue FFF.

Again, that's way more motor than I'd probably use.

Third choice, ironically, would be a pylon racer like Chellie's Gee Bee, but I'd lean towards the less-deadly sportster models.

I scratch build from pretty rough 'plans,' usually just enough to get the size and shape of the wings, tail and fuse correct. Stringers, firewalls, battery compartments etc. are never included.

I have not contributed so far because it seems to me just about every possible configuration of a flat sheet plane has already been done.
Surely this is the attraction of the moulded ARTF foamy. It has 3 dimensional bits so 'looks' more like a real plane yet each part is still basically a single piece of foam and with high volume production the cost is modest.

Thus my thinking turned towards what you might 'build' from a single sheet of Depron and how simple could the construction actually be.

I suppose what I am thinking of is something for the first time builder but using foam instead of balsa.

My scale 40" Super Cub used just a single Depron sheet but simple to build? Not really.

I think in configuration terms - I agree ...

My aim is to jog even reluctant people to have a go .. as I say - it doesn't even have to prove itself in flight. It's more a fantasy trip in a plan / drawing.

Even the un-flyable that may be put forward here - some other enterprising member would look at and figure out how to get it to fly.

At end of day ... a plane is usually based on a long slender box with two different span aerofoils across it and a power plant at front middle or back.

Once I get through the current drama I'm involved in - I shall put cursor to screen and sketch out something ...

I have this little Fokker DR1 that I scratchbuilt and it turned out to be very aerobatic. I was thinking of building a purpose built tripe just for aerobatics With the short span, the roll rate is a blur with ails on all three wings.
Have to dig up the toilet paper and crayon I guess.
