Scale model that Stunts? Start the Thread where?
« on: April 01, 2012, 09:35:48 AM »
Best place to start a Thread on a project that really doesn't fit in the Stunt Forums or the Scale Forums?

A scale model that stunts.

For those interested in scale models, well, even a scale model that can stunt, here's my preliminary first drawing.

Terrible photo, sorry about that.

Probably run the Thread in the Scale Forum.

65.5" in span
53" in length
851.5 sq. inches

Corsair F2G-1

A similar topic appeared recently, with good responses.  Perhaps it deserves to be re-introduced.  The main gist revolved around whether a model was a scale that would stunt, or a stunter that looks like a scale plane.

I'm in the camp that thinks all capable stunters should look like a real plane, and not just 100% designed for all-out aerodynamics.

The best place to put it would be the board named Stunt Design.

Here is a picture of a Corsair for super semi scale stunt.  (That is the one on the left.)  By Kirk Mullinnex.  Fies very well.  If you would practice, he would be a top competitor at any level.

But then the well-heeled will just build a 32-foot wingspan Impact with a big Lycoming in it.

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

It takes a heck of a modeler to make a flap linkage like that and have sufficiently low friction and asymmetry to fly good stunt.  Kirk is a real modeler.

There seems to be an inherent limitation in this concept, though:

Howard,

I actually developed a linkage sytem that will allow for full flap movement in both directions.

Then, when, and if called upon, the linkage system allows for just the lowering of the flaps for slow fly buys or for landings.

Works smooth as silk.

Care to guess how it's designed?

I would have a contest but, this one is way too easy.

What Howard was talking about is that Kirk's Corsair has full span flaps (it is a full stunt ship afterall).  That means that there were universal linkages to connect those flaps across that inverted gull wing.  Kirk made his own universal joints and there is absolutely no play in those linkages/joints.  Remarkable!!!!

Thanks for the reply,

I considered using universals and they are available off the shelf.

Be interesting to see plans of all this, could aid me with my design, possibly even save me some design time and trouble.

Where's the Thread? I did a search and came up empty.

Plans? What size is his model? More photos?

Thanks again for that information.

Avaiojet,
I have a plans list with over 160 designs, many which are based on scale planes.  Some even convincingly scale-like.  Send me a line and I'll send you the plans list.  I can also send PDF files if you want to look specifically at any of them.  BTW, I did do the design of the Brodak Corsair if you would like something in the 40-46 class plane.
