Well now, I am still narrowing down my choices of what to build......hmmmm
It will be made of FF foam and 6mm Depron with a sprinkling of tree parts in and out of it....lol.
Ok that WAS the intention......lol, I saw a book in the thrift shop today and suddenly found my build for this contest! It was a book called "Tom Swift and his Flying Laboratory".....and the second page had my plane in it. It's a swept wing tail-less jet design that should be a cool flyer.
Specs:
41in WS
36in Length
2212-6 2200kv motor...6x4 prop
3s 2200mh
under 20oz AUW

Cool!
But I can see quite a bit in that which could make it a bit tricky to fly!

I'm anxious to see what Wrench66 can do with it

I agree with both here......I do think those sharp delta wing tips could be a source of probs......I already have a revision planned for that
SJ I do believe the artist's idea was just that, but being as I have a hard head and don't take being told I can't very well....well, haha I'm gonna build it with just a touch different design but still keeping with the Tomorrowland theme
OK, essentially this plane is a flying wing.....being as it has no horiz tail the main wing will be doing all of the control save for a rudder. The pointy wingtips and the triangular wing are getting just a touch different geometry.....the TE will have some angle to it AND the wing tips will be squared off. I believe those two variations will help with making this a successful flying model
Here's a couple pics of my wing so far.

As Alexander Lippisch discovered a 'delta' is aerodynamically different to a flying wing in that it does have natural stability where as a wing has to have some reflex on the trailing edge.
The 'steeper' the sweep of the delta the better its the longitudinal stability becomes so it is quite possible that a more 'dart' like wing will actually be easier to fly than one that is more like a flying wing.
I have built and flown Delta's and flying wing's and yes they have quite different personalities from each other. This project will be using a wing type I designed with a good 40 degree+ sweep that has flown as a normal flying wing for many years now......only here I am building a fuse to it and removing the side winglets for a single vertical stab rearward of the wing tips. Also moving the power and weight moments around (the fuse will hold the motor at the rear and battery in it's nose) but leaving the wing's CG where it has worked well previously.
Ever since I first flew this design of wing I have wondered how it would do paired up with a fuselage built for it?
We're gonna see. --Ray
So here are a few pics and up date
Firstly I had to assemble my cut out wing cores, these are dead simple to mark and cut and unlike a flat wing, these wind up with a nice airfoil that flies very smoothly.
So here I'm drawing and cutting out a fuselage that looks right AND has enough nose to possibly counter any balance issues caused by the motor being stuck under the tail
I like to use a forward battery compartment and nose made from a solid block of industrial blue foam.....like they would use to ship large items in. This foam has served me very well in motor mounts, wing saddles and battery bays
More to come.....
More fuselage and wing saddle pics......haven't decided yet as to how I will attach the wing, might just permanently glue it on. Working with the motor mount tonite
The last pic is my chosen power train is a combo I really like and have used on other pushers I enjoy flying......Grayson 2208-12 1800kv, 30A esc and CHL 1300 30c 3s.

Revising Tom's plane
looking forward to it's completion. stu
....choose the narrow way!
Dont forget that I get to do the Maiden flight on it
