Estes - The Dude (2199) [2001-2003]
Contributed by Joe Cacciatore
It costs $19.97 at Walmart and that includes a launch pad and controller! The launch pad is just a plastic stake that you stick in the ground with a three piece rod that screws together (almost like the Aerotech Mantis rod but slightly smaller diameter) and a large 10.5" blast deflector. The controller is a standard Electron Beam. I don't think the rod is very good and it bent a lot with the weight of the rocket and with a small breeze. Construction: At the top of the rocket (actually 18" down) is the nose ring and it houses the weights which are required to properly set the CG. The ring is already pre-assembled and is held in place by tape. The plastic fin/motor mount assembly takes about an hour to put together and most of that time is waiting for the glue to dry. The fins consist of a plastic frame and a sheet of mylar glued to it. The fins are already assembled.
Estes gives you a straw to blow up the balloon. I used helium instead of air which has been stated on the Newsgroups to lighten up the rocket by 2 ozs. It blows up fast. But after 2 days it was getting limp as the air was leaking out of it. The launch lugs are attached to the balloon using tape. The tape is supplied. The instructions are typical Estes with pictures and words in English and French. The whole thing goes together really fast. There is one thing to look out for. You are instructed to insert these 3 plastic ring supports into the body ring using one drop of glue. Be careful here. If you use too much glue and clog up the rectangular opening, you won't be able to insert the fin assembly tabs later on. Also, one other point which isn't clear is they say position the nose ring 18" from the tip of the rocket. But it isn't clear if you measure 18" to the top or bottom of the nose ring. The ring itself is about 1". I don't think it is critical. The whole assembled rocket is kind of flimsy with a lot of flex in the large fins. Finishing: Construction Rating: 4 out of 5
Recovery:
Flight Rating: 3 out of 5 Summary: Pro: Its big, its cheap, it flies good, it draws a crowd. It goes together very quickly. It goes only about 300' so you can fly it almost anywhere. It comes with a launch pad and controller. Con: It rips easy and the launch rod is too flexible. Overall Rating: 3 out of 5 Flight Log

Brief:
The motor mount is plastic and houses a D12-3. There is a retaining plastic cap that holds the motor in place. At the top of the motor mount is a right angle plastic pipe and a cardboard tube which sticks out about 3" from the side of the rocket. The wadding and parachute are stuff in there. The motor mount/right angle tube/cardboard tube assembly is already put together for you along with the chute. From the nose ring up on top is attached a fishing line which drapes down along the outside of the rocket and is attached to the chute.
Flight:
On the second flight I removed the tape wrapped on the rod at 19" because I felt it was holding the rocket too far up on the rod, causing the rod to bend even more than what it could handle. And I still could not get the rocket aimed the way I wanted because of the bending rod and wind. Removing the tape was a mistake. Because on the second flight with the engine almost sitting on the deflector, the engine blast deflected off the deflector and hit AND MELTED the balloon. Even before the rocket clear the rod, the rocket was deflated enough to make it go out of control and crash right near the pad. I have a video of it on my site (click button above or below) on the rocket video page. Attached you see a picture of the bottom of the rocket with the melted holes.
