Muciano Bullet
« on: January 24, 2013, 03:22:49 PM »
The most recent issue of Control Line World has a centerfold set of plans for the Bullet.  I am scratching one out, but having never built the Scientific version, I have a couple of questions that I hope someone can help with.  First, did the original version have a one piece wing with the trailing edge fill piece or was there a left and right half joined in the center and the trailing edge piece glued on?  If it had L & R halves, was there dihedral or just built flat like the rest of the hollow logs?  The design kind of crys out for dihedral but my guess is it's flat.  Also was the original wing a flat bottom airfoil or a wedge shaped hunk of wood like the Black Hawk kits, or am I just getting carried away trying to reinvent the hollow log? 
Thanks! H^^ /DV

I submitted the plans.  Mine has no dihedral.

As I recall, I used one piece for wood for the wing.  There is certainly no center splice.  I may have cut the taper off the leading edge and glued the offcut back onto the trailing edge to minimize scrap.  In that case there would be a small splice on the TE.  I put the controls on top of the wing to get to fly better both ways.

With planes this small and thin balsa wings I just round the LE and sharpen the TE a matter of principle.  A sheet wood wing is so far from true airfoil that it doesn't matter much what you do.  Just pick a design with the most available wing area and build light.

Dave,
I am not familiar with the bullet kit, but most of the original Scientific kits used a one piece wing, nominally 18 x 3 inches, flat on the bottom, shaped with an airfoil ? (basically flat) on top. Any tapered pieces were just glued on. No dihedral on any kit I ever saw.
As Paul said build light.
I've attached one of the original plans which used the glued on pieces for the TE

The Bullet is superior in that it has a high aspect ratio wing with a span of 21 or 22" vs the usual 18".

The other "good" choices are the Stuntmaster & Golden Hawk with 18" x 4" wings. the extra 33% of wing area is huge.

Thats what attracted me to the Bullet, I love the high aspect ratio wing

Scientific kits up through the early sixties had airfoiled wings that were 1/4" or 5/16" thick. They usually featured OK Cub engines in them. Probably for cost reasons, the wings were thinned to 1/8" or so and the kits were updated with the more popular Cox tanked engines.

At least that's the way I remember them.

George.
I think you are correct. The plan I posted is from a later kit and does not have any airfoil, but the earlier kits did, and they had thicker wings.
