Re: Coro -vs- Foam Theory in Dynamics Statics

Let me interject some wisdom to all this mayhem.
First off, both wings will deform in high speed flight.
In all actuality, the foam wing on a Gremlin will flex and
bend more so than the corrogated wing of The Sickle with
a spar running through it. (dependent on spar material ofcourse)
However, the corrogated wing will allow for more deformation within the crust of the airfoil at high acceleration, but only a
negligible effect on the acceleration produced by the force system or on the reactions required to maintain equilibrium of the body according to Newton's second law. "Change in Motion is proportional to the moving force impressed and takes place in the direction of the straight line in which such force is impressed."
You see... It isn't about the flexing or movement of the wing.
All material can bend and flex. Even steel when in proportion with
an extreme velocity. Reaction is always equal and opposite to action.
There really has been only one valid point made through out
this whole thread. Even this point does not dip down into the
R.C. world unless you are running something in the area of 200 + mph. The point made about the air foil shape would then be critical. In an extremely fast instance (200+mph) the smooth round air foil would win the argument. Not in the R.C. world.
Not enough acceleration or extreme velocity to affect any pitch what so ever. If you are really flying these combat, you may even
want to sharpen these edges.
Now. Lets get back to flying.

Huh? The only thing that made sense to me is "lets go back to flying." !!

(coro or foam, coro covered foam, glassed foam, hollow coro, sharp or blunt LE... we CAN all get along! Just build the damn thing and fly it!

I got a great idea. :idea:
Let s all meet at Hooters!!! We can talk about this there, and
check out some nice ***** at the same time. I think THIS is
something we can all agree on.
