Always liked Fate ( Jack Lemmon The Great Race ) he had some flying bricks and wild looking stuff, so have I. Some I have are just flying bricks, others just fly like they are supposed to. The closer you are to a conventional shape, the easyer this is. Golden age pioneer age stuff is really interesting. DH2s FE2s French and English pusher biplanes and the Morane Saulnier type N. This was the 1st one to take a mounted machine gun ( French ) with steel plates, every 10 shots, one might bounce back at you.
Morane Saulnier N: WS = 48", L = 34", W = 2.5 - 3#, power 3s 3AH w/ Cobra Motor 10 x 5 prop 2.25" Black Spinner, 40A Esc w/ 5A BEC
Fuse: Fiberglass or Wood in front, LitePly frames n 1/8" dowels aft of wing shoulder, stained balsa covered in monocote
Wing: Balsa n Spar built using Profili for airfoil gen. Lifting airfoil close to flat-bottom 9" chord cover in cream or clear w/ stain
My goal, making this up free style as I go, but generally, following a 3 view, to make dimensions for a 48 inch WS Morane Saulnier N.
Been struggling with this, I draw a lot with paint shop pro ver 10 to look at things and figure them out get a sense for the scale, PSP lets me enlarge to full size n measure w/ rulers and grids and great precision.
A really useful formula I made up for scaling 3v drawings is what I call WRX
W = size you want (typically wing span), X = existing size of your drawing ( Wing Span again ), R = rate of expansion or enlargement W/RX.
If you draw this in just like the old pie formula d/rt and cover up the one you want to know, you are left with what to do. 3 formulas in one mnemonic.
Cover up R, leaving W size you want divided by X existing size of your 3view picture. This gives you % to enlarge.
W = 48 inches , My 3view X = 29 inches, 48/29 = 1.655 ok enlarge drawing 166%, that will give WS pic of 48 inches.
Cool huh? You might have just guessed b4 till you got it, but now you have a way to get it exactly the first time.
At WS of 48 inches, this gives a chord length of 9.25 inches to the Morane Saulnier, OK the 57 inch FT Storch also has a chord of about 9 inches and weighs 2.25 - 2.5 #.
I was all about building the Storch but undecided on how to build it with what materials. FGlass fuse or foam board? Balsa n Spar wing or foam board?
In hobby lobby picking up some of those ultimate surebonder acrylsticks, I got 2 packs, was thinking of dowels instead of BBQ skewers to attach the wing, and then a great build method occured to me using 1/8" Lite Ply frames with holes drilled around the perimeter that these 1/8" x 36" dowel rods would be inserted thru ( 29 cents each ). The outsides of the dowels flush also with frames outside. Now balsa slats 1/8 thick by 1/4 to 1/2" wide are glued on the dowels as runners to be stained and to leave a clear space between to see thru. With a total of 8 - 10 dowels on the circle of the frames this would be pretty light and stout too. This to be covered with clear Monocote. There is a youtube video of a cheap alternative to Monocote, clear or colored cellowrap and similar at the Dollar Stores, Hobby Lobby, Fam$, HEB, Walmart too.
These wraps can be had for as little as $1 a roll for as much as 10 feet / roll. You just have to glue it on with anything, 3m77, E6000, or other flexy heat activated glues. I will probably use my role of clear Monocoat but I did buy 10 rolls of cello to play with too. The guy on youtube video glues cello with 3m77 to a foam frame tight as a snare drum with hole in middle 16 inches across and demonstrates how tight and strong. Good idea.
Well this you see is on the proverbial drawing board first, while others might get out the foam n glue and stick stuff together, I sometimes play with paint shop till I like what I have then another better build method may come to me.
Now here's what I have been struggling with up to this point, that I want to streamline the Morane, make the fuse thinner and see if it still looks good or anemic, then work out the other shapes. This is going to be an impressionistic free style version of the Morane, not an exact scale of it.
The FT Storch at 57"WS, should have a chord of about 7 or 8 inches not 9.25, see it's not scale either but it sure flies n floats good!
The 48" WS Morane should have a fuse width of about 5.75 inches (my Apprentice is 5.75"wide); no, I want it to penetrate the wind like an arrow or a torpedo, not like a whale.
Below I tested this to see how it would look width-wise, and I think it will work and look good too.
So later in the design work, having made the determination for 4 to 4.5 inch max width, the current work is what to decide about the side view. I'll show a picture of my variation on this. I have lengthened the nose 6 inches for better balance, flattened the bottom, tapered the nose to take a 2.25" black dubro spinner and I checked to see if the largest motors X plate will fit inside the narrowed nose I made for the Morane, it needed 1.96", it works.
Trouble is now that I just don't want the simple appearance of a featureless flying torpedo or something like my gasser UltraStick, no pilot, just a flying "stick".
This will look like a Golden Age work of art with stained wood, clear covering in some areas, nice complex curves and maybe some cool looking wheels too!
No .... no build pics yet! This is the design work, BUT, the pictures are becoming... just like Buffalo Bill and the Red Dragon!
