Tandem-X™ Launch Set

(78 customer reviews)

Big value and even bigger fun! The Tandem-X Launch Set includes the impressive, easy-to-assemble Amazon rocket (over 29 in. tall!) and the high-performance Crossfire ISX rocket. The Amazon builds quick with pre-colored plastic parts and self-stick graphics. The Crossfire ISX is a perfect next-step to an Intermediate level model with laser cut wood fins and self-stick decals.

Two is better than one! This exceptional rocket set features a pair of extreme, high performance rockets and a launch system.

The Beginner level Amazon is as imposing as the name sounds. This giant stands almost 30 inches tall and is quick and easy to build! A black body tube, precolored plastic nose cone and fins and a tiger striped self-stick decals make building this rocket easy to do in about an hour. When flown on our Estes standard model rocket engines, this huge rocket can reach heights over 650 feet.

The Crossfire ISX is an Intermediate level kit that can easily be built in about a day. This rocket features a totally streamlined shape with aerodynamic fins and nose cone. It stands 15.6 inches tall. When launched with powerful Estes standard model rocket engines, this bullet can reach cloud busting heights up 1,150 feet. A 12 inch parachute returns the Crossfire back to earth to launch again and again.

    A great birthday gift!

    I bought this for my daughter for her 12th birthday. With my 1970s experience and her intelligence we had the Amazon in the air in a cppl hrs. She loves rockets as much as I do/did now. We flew all afternoon and built the crossfire the next cppl nights in between running out to fly. Buy plenty of engines, this set never looses it’s fun.

    Great First Time Rocket kit

    I bought it for my 8yr old son and I to build and launch. Launched the Amazon this past weekend, great fun, easy to build! Looking forward too the crossfire launch next!

  3. Ryan

    perfect launch set

    the tandem x launch set is fun and easy to use. the amazon builds slightly faster than the crossfire but the crossfire will fly higher. both rockets are great and they as well as the launch pad will last forever.

    Excellent Place to Start

    I thought that I’d enjoy picking up a hobby I enjoyed as a child, so I started with this set. This one seemed to offer the best variety and value compared to the other launch sets and I wasn’t disappointed. Both kits are easy enough to assemble (although I forgot how terrible I am at painting) and fly well. Don’t underestimate the power of your engines! Even a B is enough to put the Crossfire almost out of sight.

    Sweet buy…

    This is a WHOLE KIT, I purchased it because there is no better way to show you a difference between an EZ1 skill level and a skill level 1 rocket, and provides the launch kit all in one inexpensive package. YOU WILL NEED to still purchase plastic cement and craft glues, the motors, recovery wadding, and have 4 AA batteries.

    Best launch set Ever

    I bought my first Estes launch set in 1957. This launch set, with it’s choice of two very different rockets, is the launch set I’ve ever seen Estes offer.

    Great launch set

    Ive built all the rockets(ive messed up on the cross fire a little bit) And they still work great!:D

  8. T dub


    Have not built the cross fire yet but the amazon is awesome. dad and I went out for the first few shots there was a slight wind so we put the launch pad at an angle and shot it The rocket went straight into the corn in our back yard

    Great deal

    Was shopping with my 7 year old nephew and spotted this on the shelf. Hadn’t built a model rocket since I was in high school but thought it would be fun for my nephew. The Amazon E2X was so easy to build that even a 7 year old could figure it out and the Crossfire ISX allowed me to call up my long dormant modeling skills. Both models were excellent fliers and the launch system worked well.

    Great starter kit

    This was a present for me and my son. The Amazon was perfect for him cause its assembly is straight forward. Countless hours of quality time spent together and he and I really enjoy it.
