Inverted Gull Wings...


Skytek,

Well, I know this will sound a bit odd, but the use of the inverted gull-wing was simply an easy way to give extra clearance for the massive 13 foot Hamilton Standard Hydromatic three-blade propeller that Vought used to harness the tremendous energy produced by the extremely powerful 18-cylinder Pratt & Whitney R-2800 Double Wasp radial.

The design team headed by Rex Beisel had to figure out a way to give the massive prop clearance without lengthening the landing gear....Hmmm....hence the inverted gull-wing design!

I know it sounds strange, but now you know "the rest of the story".....

When I first saw this thread I thought it was a product announcement for a UMX Wildcat.

The disappointment.

I still want the LX Wildcat..

Don't worry brother....if we keep squeaking, maybe Horizon will provide us with the UMX Wildcat.....

The perfect solution for a new 2S UMX Parkflyer....!!

Absolutely no interest in the LX F4F......the panel lines alone are a turn-off.....

There is more to it than that, it was also done to make the landing gear stronger for carrier use and also during wind tunnel test they found they didn't need fairings at the root of the wing.

I wasn't thrilled about the inaccuracies of the LX model. But the wildcat is my favorite aircraft of all time. And there aren't exactly a lot of options out there. When I was in my teens, I bought plans out of MAN thinking that someday I would build it. That never happened, so I figured 30 years was long enough to wait for a model that was close enough and had retracts to boot.

Those were the results of the primary reason, which was to give adequate clearance for the prop without having overly long landing gear legs....

As long as we're sharing stories...my first plane plastic model kit was a Wildcat.

Back in the 70s, some grocery stores gave stamps for amount spent and you can trade in for stuff. Mom traded in for her things and had leftover so my brother and I got a 3 model kit package. I lost the coin toss so got 1 and chose Wildcat. He got Buffalo and a Japanese float plane.

Don't have that Wildcat anymore. As an adult with airbrush skills, I built a nice 1/48 scale in my display case. For RC, I got a Funfighter Wildcat so I'm some what satisfied. It's by far the best flier of my 30+ hangar.

I'll still take a UMX any day!!!

Sounds like you got your Wildcat courtesy of Blue Chip Stamps; I remember 'em well, you used to stick them in a book/catalogue and when it was full you could turn it in for stuff.....

Simpler times.....

Same here! I would even support a Kickstarter or Gofundme if there was such a project on the table.

Neat idea. A lot of us have a totalled umx plane laying around, so even an airframe that could use the donated parts would work. Unpainted would be super cool!

So let's think about this. If they design a UMX Wildcat how would the landing gear best be designed? We could have fake wheels shaped into the fuselage like the larger version and keep it purely as a belly lander. Any attempt at actual clip-in landing gear would probably ruin the look. Retracts while a dream scenario, would not be practical at this scale. Your thoughts, gentlemen?
