Looks like the XC-142A (not the best photos from the old NMUSAF Experimental and Presidental Aircraft annex)

I found this VTOL cargo with tiltwing in an old French comics, is this a XC-142 or imagination?


Nice.  I'd like to build something like that but the wing tilt would have to be working so it'd take a bit of engineering to do properly.
How do I calculate lifting capacity based on engine horsepower and propeller size?
Maybe just go with the "if it looks right it is right" principle.

I wish you could do it. :thumbsup:
Don't be afraid: I will not argue that the propeller diameter is not perfect or something, as we are what-ifers, and a secret change in properties may explain all, what-if? ;D

Or look at what Vought/LTV did here

The C-142 was powered by four General Electric T64 turboshaft engines cross-linked on a common driveshaft, which eliminated engine-out asymmetric thrust problems during V/STOL operations, to drive four 15.5-foot (4.7 m) Hamilton Standard fiberglass propellers. Compared to conventional designs it was overpowered: it had 0.27 hp/lb, compared to 0.12 hp/lb for the contemporary Lockheed C-130D Hercules. This extra power was required for safe VTOL operations, and gave the aircraft excellent all-around performance which included a maximum speed of over 400 mph (640 km/h), making it one of the fastest VTOL transport aircraft of the era.

Thanks for this link, including the Canadair CL-43 twin-boom project 3-view, rare! :thumbsup:

Thanks Jon.  The tilt wing concept may be the answer to the question "how do I whiff this Airfix Skyvan?"

<edit> Just skimmed the file you linked to.  Excellent! Lots of whiffsperation there.  I haven't yet built a tilt wing with props so that'll be first but i'd like to revisit the tilt fan concept sometime.  I need to keep an eye out for suitable sized fans as scratchbilding them is very time consuming.  Computer cooling fans maybe?

Please do! I had started playing with that very idea a few years ago only for R/C and still plan to do so sometime, be great to see a plastic version. :mellow:

If you do find something suitable and Cheap!, can you please let the rest of us know?
I for one have a couple of ideas but I'm put off by the thought of scratchbuilding Two! engines with Contra-rotating! fans...  :banghead: :
Oh, and did I mention they are to be Shrouded?!  :banghead: :banghead:

Yes. Cheap is the operative word here.  I'm sure I could find computer fans that looked perfect but then would have to junk the motors and casings which would be wasteful and expensive.

Perhaps using the fans from old and non-working PCs could be a solution? At the last count I have at least four large size PCs knocking about the place, and there must be a few fans in there.

Garden sheds, attics and basements all over the world could be a suitable source.  ;D
Any aircraft can be improved by fitting longer wings, and/or a longer fuselage

...and I'm not a closeted 'Take That' fan, I'm a REAL fan! :)

Must admit I've been musing on the idea of an RAF tiltwing transport for the GB
