Glider Thang

Why Glider Thang? Well, what else would a Southerner call a rocket, er…an aircraft…uh, well it’s a Glider Thang. See? Here it is…enjoy!

Glider Thang is a great demonstration rocket for schools. The maximum altitude with an Estes D12-3 is about 200 to 250 feet (on a good day). OK, maybe its wishful thinking, but I have had glide times of almost one minute with well trimmed gliders.The two foot wingspan gliders were bought at a local discount store for $1.97 each.The only other needed parts are: two sections of BT-60, one tube coupler, a nose cone (I used one from the Prowler kit), a three inch piece of BT-50 (engine mount), one “D” engine block, two CR-50/60 centering rings, a motor hook (if you want) and an 18 inch parachute for the booster. Of course you’ll need two pieces of 3/16 inch launch lug and some shock cord material.Here are the other details. Use plywood for the glider hooks. The receivers can be made of hard balsa.

The launch lugs are mounted between the glider mounts, one flush with the bottom of the tube and the other in a striaght line 14 inches above the lower lug. A four foot launch rod is recommended. The first booster was never painted. I did use an iron-on covering material for model airplanes for the second one. I also made an ejection baffle for the second one so I don’t have to use recovery wadding. This makes the turn-around time just about two minutes. Just pack the parachute, install a new engine and head to the pads. It is easier to install the gliders after the booster is on the pad and the micro clips have been attached to the ignitor.Glider Thang always gets oohs and ahhs at the field. Have fun and enjoy.John Stein
