Overview

The Estes A8-3 Engine Bulk Pack is designed to make classroom rocketry easier, safer, and more engaging for students. These engines are perfect for lightweight rockets and deliver reliable thrust for an exciting yet manageable launch experience. The 3 second delay allows students to observe the complete flight sequence from launch to parachute deployment, creating an excellent opportunity for data collection and analysis.

Teachers and group leaders appreciate the A8-3 engine for its consistent performance and predictable results. It helps ensure every student gets a successful launch experience while reinforcing key STEM concepts such as thrust, drag, and recovery. The A8-3 provides a balance of safety and excitement that makes it ideal for educational environments and youth programs.

Each bulk pack includes enough rocket engines, starters, plugs, and recovery wadding for 24 launches. This convenient packaging saves time and makes it easy to organize group launch events. Students can focus on applying scientific principles, recording flight data, and comparing results while the A8-3 engines handle the reliable performance needed for repeated flights.

The Estes A8-3 Engine Bulk Pack is recommended for use with popular classroom rocket kits such as the Alpha, Alpha III, Generic E2X, Wizard, and Viking Bulk Packs. Pair it with Estes launch systems and safety equipment to give students a hands-on, educational experience that brings science and engineering to life.

Good engines

I use LOTS of A8-3 engines every year. I'm disappointed in the price increase, though.

Top Notch Customer Service

I do purchasing for a middle school, and our science teacher does a rocket unit with his 8th graders. We typically order through Amazon with a business account with discounts. By the time I went to order from when the purchase order was filled out, the price had skyrocketed. I tried this site, but they were out. I was able to sign up to receive an email when they were back in stock (which happened quickly). I placed my order then sent an email to customer service inquiring about tax exempt status. I received a reply quickly, and they told me about a teachers' account. They signed me up for it and refunded the sales tax. Smooth process from start to finish. Thank you!
