Excelsior Rocketry - Goonydent

Manufacturer:Excelsior Rocketry

Construction Rating:
Flight Rating:
Overall Rating:

Contributed by Steve Lindeman


The Goonydent is Excelsior Rocketry's Goony version of the Estes classic Trident kit [K-33, 1233](1968-1974). It was by far the most expensive kit bash I've done so far at a cost of about $45.00. However the end results were worth the investment.


For this build I used the following components:

 ♦ 1- Set of plans and decals from Excelsior Rocketry

 ♦ 2- Baby Bertha Kits (#'s 16 & 17 for those of you that have followed my Goonyness)

 ♦ 1- BNC-60 (Baby Bertha style)

 ♦ 6- BNC-5's (Mosquito style)

 ♦ 3- 18" BT-5 tubes

 ♦ 1- 24mm Motor Mount (with 2 CR's)

 ♦ 1- 18" Plastic Parachute (from an old Estes rocket)

 ♦ 1- 3'x1/4" Elastic Cord

 ♦ 2- 3/16" Launch Lugs

Favorite Rockets: Estes Falcon Commander


I've been building and flying model rockets since being intoduced to my first rocket in 1979, a Estes Alpha III. I didn't know anything about rockets at that time and all i did was glue the nosecne to the plastic fins and threw it around in my backyard. My first real rocket was a Estes Falcon Commander starter kit in 1981. Within a few years of cutting grass and saving money my fleet grew to over 10 rockets. 

I eventually got into bigger D powered rockets and my first was a estes mach-2. I built it as best as i could and it turned out very nice. Off to my flying field for its maiden flight. I stuck in a D12-5 and set it on my then, new estes big foot launch pad and after inserting the saftey key and pressing the button on my "power pulse" controller the rocket soon blasted off into the blue sky turning into a orange dot. At that moment I knew that was going to be its last flighht. as after nearly 1/4 mile hike it was still drifting into the woods on its 18" chute...Oppps...


since then Ive been hooked into model rocketry.

Model Rocket Building: Peter Alway Saturn IV Build, Part 1, Plans and Parts
This model was from Peter Alway's Home Page. I can't seem to find it now! If anybody has a link, let me know. The website had plenty of sport and scale plans including a Vostok, Saturn I and a Flying Rabbit that looks better than the old Estes Cloud Hopper. You can get Peter Alway's books: Rockets of the World HERE and Scale Bash HERE Both highly recommended! There's one model that has been on my "to-do" list for a while. The SATURN IV! This is Peter's "psuedo-scale" design of a Saturn that could have existed between the Saturn 1 and Saturn V, the Saturn IV. Full resolution plans aren't ...

Model Rocket Building: Asking Permission Might Be A Good Start!
If you follow the blog, you might recognize this rocket. It's my two engine cluster model called the Big Girtha. It was adapted from a Quest Big Betty kit. I took this picture before it was launched at the Tampa TTRA monthly. Then I saw it in a EBAY listing. Maybe I should be flattered, but I'm not. A vendor was selling his 808 "Spy" cameras using my picture. Farther down the Ebay listing is a link to my YouTube video from the flight. I didn't buy and build the rocket, buy the camera, fly it, edit the video and post it for somebody else to make a profit. Build your own model, fly your ...
