Estes Tandem-X Launch Set vs Estes Alpha III Launch Set
Which should you buy? Our verdict on both, pulled from our full The Best Model Rocket Kits: 4 Compared (and One to Skip) comparison.
The Tandem-X is the starter set to buy: two rockets (a 30-inch beginner build and a 1,150-foot Crossfire ISX), a launch pad and a controller for $45. The Alpha III is the classic single-rocket alternative. The Roto Rocket is the STEM it-depends with a helicopter recovery. Skip the stomp-rocket set - it's a toy, not a model rocket.

Estes Tandem-X Launch Set
Buy itTwo rockets and a full launch system in one box - a 30-inch beginner build plus a 1,150-foot intermediate rocket for $45.
- Two rockets in the box: the 30-inch Amazon (beginner, about an hour to build, 600+ ft on C6-5) and the Crossfire ISX (intermediate, up to 1,150 ft on C6-7).
- Porta-Pad II launch pad and Electron Beam push-button controller included - the launch system, not just the rockets.
- Parachute recovery on both rockets - launch, recover, relaunch, the real model-rocketry loop.
- $45 for two rockets plus the pad is the best entry value in model rocketry - the classic starter gift.
- Engines not included - it needs Estes A/B/C motors, controller batteries and basic building supplies bought separately.
- Recovery means chasing: a 1,150-foot flight drifts far, so it wants a big open field, not a backyard.
- The beginner Amazon is plastic-finned and basic - the real fun is in the Crossfire's speed.

Estes Alpha III Launch Set
Buy itThe rocket that's launched generations - a fast-building beginner set with pad and controller for $40.
- The Alpha III is the most proven beginner rocket ever sold - the first in Estes' Beginner series, simple and reliable.
- Quick, easy assembly meant for a first build - streamlined design, minimal parts, fast to the pad.
- Launch pad and Electron Beam controller included - the full launch system in one box.
- $40 is the cheapest complete launch set here - the classic "first rocket" gift.
- One rocket, not two - the Tandem-X's second rocket is worth the extra $5 for most gift-buyers.
- Engines, batteries and building supplies still sold separately.
- Lower ceiling than the intermediate rockets - it's a first rocket, not a fast one.
