Elevate your model rocketry experience with Estes Upper Stage Rocket Engines, meticulously engineered to power the second or third stage of multi-stage rockets. These engines provide the sustained thrust needed after booster burnout, propelling your rocket into the upper atmosphere with accuracy and control.
Engines like the D12-7, C6-7, B6-6, and 1/2A3-4T feature long delay times —ideal for upper stage ignition and coast before ejection. These delays are precisely timed to deploy your recovery system at or near apogee, resulting in safer and more efficient flights.
From lightweight launches using the A8-5 to powerful flights with the E12-8, F15-8, and E16-8, this collection covers a full range of upper stage needs. Whether you're experimenting with staging or optimizing altitude performance, you'll find the right combination of impulse and burn time to match your flight profile.
Designed for compatibility with Estes multi-stage kits and custom builds alike, these engines are the key to unlocking more complex and rewarding flights. Ideal for experienced rocketeers and STEM learning alike, upper stage engines open the door to higher, smarter launches.
