The Estes A8-5 Engine is a top-performing option for hobby shops and resellers looking to offer consistent, in-demand model rocket motors. Designed for rockets with a maximum lift weight of 2.0 ounces, this engine delivers up to 10.7 newtons of peak thrust and features a -5 second delay for longer coast phases and smooth ejection timing.

Its standard 18 mm diameter ensures broad compatibility across Estes rocket kits, making it a dependable and flexible item to stock. Customers appreciate the longer delay for higher-altitude flights and more controlled recoveries—especially when using the A8-5 in upper-stage or altitude-optimized single-stage builds.

Each retail pack includes three single-use engines, four igniters, and four igniter plugs, providing everything hobbyists need to launch successfully. The all-in-one packaging and reliable flight performance make it easy to merchandise and even easier to recommend to customers looking for tried-and-true engine options.

For wholesalers, the A8-5 represents strong sell-through and repeat purchase potential. As one of Estes’ most widely compatible and reliable engines, it’s a must-stock product for any model rocket inventory. Whether your customers are weekend fliers or serious hobbyists, the A8-5 delivers consistent quality and satisfaction with every launch.
