Sylph and Wombat Rocket-Powered Gliders
by David W., Santa Fe, New Mexico
visitor David Wagner, of Santa Fe, New Mexico, was kind enough to send me photos of his two very fine rocket-powered
gliders - the Sylph and the Wombat. He is also in the process building a
Cheechako rocket glider based on an article
from the February 1972 edition of American Aircraft Modeler. Hopefully, David will also send a photo of his Cheechako
when it is ready.
Here is David's note:
"I just discovered your site and decided
to build the Cheechako rocket glider you've featured. I'm also a model airplane guy who occasionally builds rockets.
I'm only interested in rocket gliders. I often build modified versions of the old 60's rocket gliders, such as the
Estes Falcon you mentioned.
I've attached a couple photos. Both of these fly very well. I always hollow out
the nose cones to place nose weight as far forward as possible. Also, drill a small exhaust hole in the nose and
on each side of the engine housing to handle the Estes ejection charges, which can be extreme and sometimes destructive.
I included a photo of the Wombat delta wing rocket glider because of it's similarity to the Cheechako. It was
built from a very old plan.I added dihedral, which I will plan to do with the Cheechako. Have you tried it with
no dihedral? "
plans for the Sylph rocket-boost glider.
Wombat Rocket-Boost Glider
Unfortunately, I was not able to locate plans for the Wombat
Edmonds Aerospace CiCi rocket-boost-glider.
The National Association of Rocketry (NAR) has webpages for
Boost Glider Plans and
Rocket Glider Plans. The difference
is that Boost Gliders may consist of any number of stages so long as the last stage is the glider, and a Rocket
Glider consists of only a single stage.
