Skyraider biplane

[Wardukw]

I've got pics of a RW DC3 float plane on one of my hard drives ..it's such a cool idea and one I've wanted to build in 48th for yrs..biggest problem..finding floats 😆
I'm jealous of Kits build cause god that looks good 👍

Nice of you to say so, thanks. It was a bit of a PITA to do as it needed TONS of nose weight everywhere, even in the engines! and getting the floats positioned wasn't easy in the slightest. I still have it but it rarely gets shown these days.

I was wondering how much of a pain it would be mounting the floats Kit ..and the weight too.
Looking at the real thing side on you can see that everything is in the wrong place for balance..real plane not much of a problem..model wise as you discovered..problem..how bad would it be in 48th I wonder 🤔

I started the removal of the bomb pylons and filled the wheel wells. I have to figure out a wing center section for the upper wings to fit over the cockpit. I think I might put the upper wing on a pylon over the cockpit rather than attach it to the top of the canopy. I've got a crazy idea to lengthen the fuselage but that might make it too complicated and run over the time span. I've got to remember to keep this simple!

How about going the Grumman\Columbia XJL-1 ÜberDuck route?You cannot view this attachment.

Interestingly when the widebody Skyraider
was developed it was slightly lengthened.

The silliest thing is that the floats are NOT centred under the engine nacelles, they're inset around a foot full size, which means the main struts need to be angled in two planes at once! Quite why Douglas didn't take the easy way out and have them directly under the nacelle centre line I've no idea.

I suspect it'd be a bit easier in 1/48 as everything would be larger and easier to handle, but of course you'd need to scratch the BIG floats and you'd need even MORE nose weight too.

This is a pretty poor pic, but it shows what I mean.

EDO designed the floats and the installation, as to the positioning it likely had something to do with load paths. The DC-3 wing design doesn't have spars, it uses Jack Northrop's "multi-cellular" wing structure design. Which was conceived in the late 1920s during his early work on the concept of the flying wing, it's his greatest legacy.

Oh dude 😳
Yeah I can clearly see what you mean ...Jon had probably answered why it's like that..nothing structural enough in the nacelles for the size of the floats and as for building the floats

Those drawings look very cool. Especially the super duck!
Working on getting the bottom of the wings smoothed out. Pylons are gone and wheel wells filled in. Just a little more putty. Famous last words. I need to work on what's holding up the top wing.

Looking forward to this matey 😄

Hey Kerick, could you use a gull wing style attachment? Per the I-153.

That's a good idea. It would keep the canopy clear for the tourists.

  Glad to help.
