P-824 or 823 Twin-Tailsittang (Crazy Mustangs step 5)
« on: September 05, 2010, 04:17:53 am »
Next model is going to be built:
*1/ I had so many P-82 kits I decided I should build the remaining ones all at once. So the final Twin-Mustang will have 4 fuselages, but I lack room, even without external wings...
*2/ I used to paint sky blue my level aircraft and golden my VTOL tailsitters, and – I don”t know why – I bought one more golden paint pot last time I ordered paint
*1+2/ This will be a cross 4-fuselage tail-sitting quadruple Mustangs!

FOUR???  :o
Any aircraft can be improved by fitting longer wings, and/or a longer fuselage

Here is the project, with simply intermeshing propellers... (to keep standard parts...):

correction: there will be no tailplane ("no need" said the engineer Mr X.Töph):

Thinking about it, this is what I should build, for balance, but with asymmetric wing profile, I fear I will fail...

Why?

I can't see any reason why that shouldn't work. So long as the master pilot decides where it's going the whole bunch of them will assume a reasonable angle of attack to the airstream. Some of the wings will be more effecient than others, but with four Merlins, or Allsions, up front it won't make much difference. It's going UP for sure!  ;D

The P-82 nose is longer than a standard Mustang. To keep some of the propeller conflict out, use two standard Mustang noses at two opposite sides. Therefore the Mustang props would be "below" the P-82 props. It would almost be a contra-prop. In fact, any two opposite noses MUST have the same rotation, so use the "handed" P-82 props wisely.



Also, take the centermost machine-guns out for wing strength. I think on your model (as opposed to the drawing) the guns will not have to fire through the propeller arc.

If you don't know the plane, google "Convair Pogo" for a version I saw fly in my home town of San Diego many years ago.

I mis-spoke, sorry. I was not meaning the airplane cannot fly or be piloted, I was meaning my modelling will fail to build it, as the wing-fuselage connection is very crurved above and almost flat below (Bernouilli principle of lift), so the central wing will be in the wrong position for the fuselage upside-down. Well, tonight dreaming, I guess I found the answer: cutting the central wing at the middle and turn half of it opposite, but it is even more complicated than that, as I must have too half starboard-central half-wings... I will see, I think I will fail but I will try I promess...
  As a dreamer, I follow you on dreaming how this airplane would fly... (funny, thanks!) ;D Well, to take off, no (big) problem, every one of the 4 pilots is in a similar position, but... what if they are in level flight? At least 2 pilots would have the legs above the head! Good for a racer, sposored by Aspirin or Paracetamol factory... :lol:

Good advice thanks, that could work actually! And I have 3 extra Mustang kits to finish also, I could do it, I will see.
I had not removed the guns from my picture because I was lazy in a week-end dreaming, but my model will have as usual no killing machine-guns, sorry. I respect your loving them while I don't.
I had built a Pogo myself, as hybrid Pogo-Komet (Poget). At http://www.whatifmodelers.com/index.php/topic,12121.0.html . Thanks to the witness you are.

That's just mental! And therefore, I love it! :wub: :lol:
Cheers,

Must, then, my projects bend to the iron yoke of a mechanical system? Is my soaring spirit to be chained down to the snail's pace of matter?

I checked the content of the boxes, and HORROR! :blink: :huh: I found only 3½ fuselages (7 halves!). So... with tears in my eyes, I considered making a P-823, well balanced anyway:

Yes Sequoia but my models have no nationality.
Well, checking the P-51 boxes also, I found the 8th halve of P-82. (Sigh of relief). So… well, 823 or 824? Maybe 823, keeping the 4th fuselage for an asymmétric twin… :rolleyes:
Here is the overview of the P-821 on the workbench and remaining P-82 parts for P-824 or 823 (from 4 Monogram kits at the beginning):

If I decided from the very beginning, I could have used 7 fuselages instead of 4 (or 3):
