  1. Rocket Guru

    Love this model rocket, for it was the first model rocket I’ve modified in 30 years. Seen the Estes Mini Fat Boy powered by 24mm composite motors, for extreme launch shock, awesomeness and has a very impressive Flame, Smoke/ Rocket ratio. I modified mine for 24mm E motors and it should see well over 2,000 feet, with through tube fins, using an Estes 9751 24mm Motor Retainer, plywood centering rings and some nose weight. Increased the strength of fins, by laminating paper and C/A adhesive, very light weight. The Estes Mini Fat boy is a great rocket to upscale to a BT-80, for a scratch built original Estes Fat Boy, mine is 29mm powered. Or, downscale to a BT-20, for a Micro Fat Boy, mine is powered by a 13mm Motor, lightweight, with 3-way break away tumble recovery, attached by a common shock cord. It rivals the Estes Mosquito for stubbiness, at 3-3/4inches long. They all look great and are very stable. Depending on you skill level, you can also cluster 3x18mm motors, or 7x13mm motors for more shock and awesome flight performance, but would install an ejection baffle. 5+Stars

    Fun build

    I had fun putting this on together and it gave a good low flight… thinking of getting another to upgrade to standard motor… hehehe

    One of my favorites

    I LOVE this little rocket! It flies nearly every time our club gets together. A10 or A3, it just works.

    Perfect for Small Fields

    It’s always nice to have small rockets for small fields and this one fits the bill. 250 feet on an A10-3T is perfect for a first launch of the day to test the wind. The only trouble you might possibly have is that the body tube is pretty short, so you’ll end up needing to fold the chute differently from usual. As it’s a skill 1 rocket, building and finishing is fairly simple. I’m not sure how everyone else does it, but the top of the T decal is significantly wider than the end of the fins, so I ended up putting my T on upside down.

    First build as a BAR

    This was the first rocket I built since the mid ’80’s. Once I finally got it completed it looked really nice (to my eye, anyway). Thanks to all the ‘help’ our new puppy gave me, I had to cut a new fin after she decided to decorate one with teeth marks 🙂

    Be aware this is a very short rocket and not a lot of room between the engine mount and the nose cone. Since it was such a tight fit, I decided to cut the base of the nose cone off so I could you that space for the ‘chute. Probably not necessary, though.

    Never got to fly it as our puppy figured out how to get up on my bench and ‘played’ with several of my rockets. I’ll build it again, though.

    Great little rocket. Simple build. Good for smaller areas . fun to see this little guy in action

    Great for a small field. I Miss the original fat boy. But this is a great replacement. It is a great flyer. The little engines are less money. Lots of fun and an easy build.

    Great little rocket

    I bought this to build in between my bigger rockets and found it to be a blast to build!! Typical excellent Estes quality. I love the shape and the waterslides are top notch. It will be a big bang for the buck because the engines are fairly inexpensive.
