Hello,

welllllll... you get a pen and go Zipppppppppp
and then you go back again and do a curved Zipppppppp on top.

it might be a actual aero... i did have a wing in half so i could had shown you, but i glued it back together.
its basicaly flat bottomed like a clark Y or sommit similar, pointed ever so slightly down to make it slightly semi, like straight line from te to Le
taking it right from your plane should be easy, just copy the fuz cut out, and draw a straight line under it

Hehe... the webiste claims "the wing is balsa covered foam with a high speed laminar flow section."

Let's bear in mind laminar flow is actually used on Airbus and Boeing aircraft @ Mach 0.82 /0.84... Which is not the case for this aircraft, and obviously not needed. The P51 Mustang also had a similar wing profile. These profiles seem to be needed at quite high speeds.

Back to our subject : I've found myself by chance in front of an old rc mag in which the Weston magnum was reviewed; At that time, it was not an ARTF but a real kit, and the wing was a mere 8 mm balsa sheet !!! No profile at all... They've changed their mind, apparently.

Thanks !

all it means is his high point of the ZIPPPPPP is a little further back :D

the kit was good, and at speed feels just as good as the current ARTF.
our club made a few Cornettos ( cheap Magnum ice creams ) with foam wings to improve the landing and about the same time the new foam winged ARTF was born.

the problem with flat wing is you need to fly at an angle to get lift which slows you down. i did alot of question asking and designed my own little Magnum with a foam wing, had a MDS 38 shoehorned into some balsa. was bloody quick, but a bear to launch because of its size. i forget the time scale of which came first, and who answered what.
