  • Estes - Baby Bertha {Kit} (1261) [2002-] By G. A. Dean

    Brief: The Baby Bertha is a new kit (2002) based on the venerable and popular Big Bertha kit. The rocket has the same large, V2-like fins and blunt, rounded nose cone as the Big B, but is 1/2 the length at 12 inches. Rated at "Level 1", it's an easy to construct kit using traditional, Estes-style methods that would make an excellent kit for a beginner, or young rocketeers. If you have ever ...

  • Baby Bertha (Modification) By Mike Goss

    It all started one day after I opened a Baby Bertha kit and found that the motor mount had the wrong size adaptor rings. The rings were for a BT-50 and not a BT-20. I thought about replacing the rings with a correct set, but then the creative juices started to flow, what could I do with this kit? I had always wanted to build a Big Bertha but had never purchased the kit. With the parts in the ...

  • Baby Bertha (Modification) By Dwayne Shmel

    This is a kit bash of a Baby Bertha that transforms a mild mannered rocket into mean, green, flying machine--the BioHazard. Modifications: One challenge was the tight fit of three 18mm motor mount tubes inside the BT-60 body tube. The 3 tubes were glued together and the inside "hole" was filled with a dollop of epoxy with a little paper wad as a backer. The 3 motor tube assembly fit inside ...

  • Baby Bertha (Clone) By Steve Lindeman

    Cloud Hopper was my second Goonybird clone that I built by kit bashing an Estes Baby Bertha and as a result has an 18mm motor mount instead of the 13mm that the original Cloud Hopper had. Components Components used for this build were one Estes Baby Berha Kit (1261) and the plans from   http://www.oldrocketplans.com/estes/est0851/est0851.htm . All parts of the Baby Bertha ...

  • Baby Bertha (Plan) By Bill Eichelberger

    Der Goony Max is an inspired bit of lunacy from Excelsior Rocketry, and I guess depending on where you stand on the Goony issue, this series is either genius or a waste of a good Baby Bertha. Speaking as the one-time-owner of an original Goonybird Cloudhopper, I happen to fall on the genius side of the ledger, and to be honest, I can't imagine anyone would fall anywhere else. Der Goony Max is ...

  • Baby Bertha (Modification) By Steve Lindeman

    Here I go again. For those of you that have followed my  Goonyness    this was  Baby Bertha kit bash  #10. Again this is not a kit review of the original  Estes   Aries SST   (Kit #1927) [1983-1984].   It is another of my many kit bashes. All fin patterns and decals came from   http://www.spacemodeling.org/JimZ/est1927.htm . The ...

  • Baby Bertha (Modification) By Steve Lindeman

    Lucky or unlucky? For those of you that have followed my  Goonyness    this was  Baby Bertha kit bash  #13. As such I wanted to play it a little safer with this one so I choose a simpler design. Again this is not a kit review of the original  Estes   Advanced Target Drone   (Kit #1913) [1983-1985].   It is yet another of my many kit ...

  • Baby Bertha (Modification) By Steve Lindeman

    Here I go again. For those of you that have followed my  Goonyness    this was  Baby Bertha kit bash  #14. Again this is not a kit review of the original  Estes   Hawkeye   (Kit #0873) [1986-1996]   It is another of my many kit bashes. All fin patterns and decals came from  http://www.spacemodeling.org/JimZ/est0873.htm .  The ...

  • Baby Bertha (Modification) By Steve Lindeman

    The Goonymarc was number eight in my line of modified Baby Bertha kit bashes. I started with the plans from Jim Z's for the Estes kit #654 with the thought of building the glider version of the Bomarc but ended up with the parachute version (kit #657). All templates and decals for this build were taken from the #657 Bomarc plans ( http://www.spacemodeling.org/JimZ/est0657.htm ). ...

  • Baby Bertha (Clone) By Steve Lindeman

    Missile Toe was number three in my line of cloned Goonybirds that was built by kit bashing another Baby Bertha kit. As such the plans and decals were downloaded from Ye Old Rocket Plans (http://plans.rocketshoppe.com/estes/est0854/est0854.htm) and used for construction guide. Components From Baby Bertha kit: 1- BT-60 Body Tube (cut to 6" in length)   1- PNC-60 ...

  • Mo' Skeeter (Upscale) By Chris Gonnerman

    This is my Mo' Skeeter, a 320% upscale of the classic Estes Mosquito . It's a rear-ejection model, which avoids the visible nose cone line that most Mosquito upscales suffer from. Components This rocket consists of a Baby Bertha cone , 6" of BT-60, 6" of BT-20, two 20-60 centering rings , a thrust ring, engine hook, and retaining ring, a launch lug, and a shock cord consisting ...

  • Baby Bertha (Modification) By Steve Lindeman

    One again this is not a kit review of the original  NASA Pegasus (Estes Kit #1376) [1982-1986]  but another of my many Baby Bertha kit bashes (#12 for those following my Goonyness). All fin patterns and decals came from   http://plans.rocketshoppe.com/estes/est1376/est1376.htm . The major difference again being that mine is a Goony version of the  NASA Pegasus. ...

  • Baby Bertha (Modification) By Stan McKiernan

    This is a Goonie of one my favorite classic boost gliders, the Sky Dart. The Sky Goon starts as a Baby Bertha and adds wings, stabilizer and engine pod. Modifications: The rear of the nose cone is removed, leaving about 1/2" of shoulder which is glued to the body. The engine mount is built as usual with the aft centering ring positioned 1" from the end. The other two rings are glued ...

  • Baby Bertha (Clone) By Steve Lindeman

    The Sky Shriek was clone number four of the original Goonybirds that I built. And as such is another  kit bashed Baby Bertha . The plans were downloaded from   http://plans.rocketshoppe.com/estes/est0855/est0855.htm . I then followed these to build the Sky Shriek with the exception of it having an 18mm motor mount instead of the 13mm mount that was in the original. ...

  • Baby Bertha (Modification) By Steve Lindeman

    The Snarky Jr. (a.k.a. Goony Shark) was kit bash #6 in what was to become a long list of Baby Bertha's that I converted into various Goony Birds and such. The inspiration for this one of course came from my DynaStar's - Snarky and the fact that I wanted to be able to fly it in the smaller "B" fields near me. Components As stated this is a kit bash  so the first thing to do ...

  • Baby Bertha (Scratch) By Mark Van Luvender

    I chose to build the Streamliner for this contest as it truly spoke to me as something I could do--that doesn't happen often. This rocket started out as an Estes Baby Bertha kit. In order to create the "Streamliner", I cut a wedge shaped section out of the body tube starting just below where the nose cone shoulder ends. Once the cut was made, the edges were glued together to create the sleek ...

  • Baby Bertha (Modification) By Steve Lindeman

    The Streamliner was the fifth in a series of Baby Bertha kit bashes that I did while building my Goonybird fleet. The first four kits were used to make four of the original Goonybirds from Estes but now it was time for somthing a little different. I remember seeing this model in a Design This Rocket contest and being a lover of retro rocket designs, I knew I wanted to build it ...

  • Baby Bertha (Modification) By Steve Lindeman

    For those of you still following my  Goonyness  this was Baby Bertha kit bash #11. Again this is not a kit review of the original  but another of my many kit bashes. All fin patterns and decals came from  http://www.spacemodeling.org/JimZ/est0806.htm . The major difference again being that mine is a Goony version of the USAF Pegasus (Estes Kit #0806). It will ...

  • Baby Bertha (Modification) By Steve Lindeman

    For those of you following my  Goonyness  this is Baby Bertha kit bash #9. So OK this is not a kit review so much as it's actually another of my kit bashes. All fin patterns and decals came from   http://www.spacemodeling.org/JimZ/estes/est1909.pdf . The main difference is that mine is a Goony version of the USSF Fireflash (Estes Kit #1909). I'm only doing this ...

  • Baby Bertha (Clone) By Steve Lindeman

    In all fairness I can't do a brief description on this kit as there is a small story behind it. As is normal for me this is not an actual review of the Estes NASA X-15 (0889) [1988-1989]. It is a kit bashed, clone by transition. I came about the idea of doing the X-15 as the G-15 after building my first eight Goonybirds. The logical choice was to wait until the 15th Baby Bertha kit ...

  • Baby Bertha (Clone) By Steve Lindeman

    Zoom Broom was the 1st of my Goonybird clones modified for 18mm motors as a result of being kit bashed from a Baby Bertha. Components Starting with a Baby Bertha kit (EST 1261) that I purchaced at my local Hobby Lobby, all components except the balsa wood and decals were used to make this build. While at hobby Lobby I also purchaced a 3/32"x4"x36" sheet of balsa for cutting the ...
