A really neat idea, found at JimZ's
plans. I hope to have pix soon.
The concept is to have a boost-glider where the glider portion is like one
of those ZZZylo (SP?) flying cylinders. The glider is made of a length of
BT101 with extra material on one end. The booster section is like the old
Scout, while the massive glider makes the whole thing look like a Streak on
A.R.G. in Mississagua, Canada, still has some BT101 for sale, 3 pieces for
$25 including shipping. I have their telephone # somewhere. I
bought some to replace a crimped Saturn V tube, and since I didn't have any use
for the other pieces, I thought this was the ideal project.
I downloaded the plans but as the printer fudged all the sizes, I ended up
having to scale the fin pattern. Not a problem. The other
modification is that the original kit called for BT30, which is like
thick BT20 with a slightly larger ID. I used BT20, and don't think
it will be a problem except it might not live as long. I also used a
BNC20N cone, which is sharper than the cone which is called for, but looks
Building up the glider is simple enough if you're handy at cuting body
tubes. I have a bunch of 11x17 card stock, which was indispensible in
cutting the tubes for the internal liner rings. I taped the card stock
around the tube which gave me a good edge to work with, then ran a new Xacto
blade lightly around the tube until it got a good start. Then I applied
more pressure until it cut the tube. A little sanding cleaned it up
I used some stainless 1/16" welding rod I had handy for the hook.
I made the hook more curved so that it will grab the engine more securely - no
chance of the casing getting past this hook! The vent hole I cut with an
Xacto knife, and soaked with CA to give it some strength and flame
It's all painted and ready to go. The glider is gold with a blue
spiral (Go Bears!) while the booster is blue and gold. I need to touch up
the booster because the masking tape pulled up some of the undercoat.
