The Estes Standard to D Engine Adapters open the door to new possibilities for your model rockets. Instead of being limited to D-size engines, you can now easily fly your D-mount rockets with standard size engines. This means more flexibility in how you enjoy your launches, whether you want shorter, lower flights for small fields or simply to extend your engine options. Quick and Easy to Use With only two steps, you’re ready to launch. Simply insert your standard engine into the adapter and then place the adapter into your rocket’s D mount. No complicated modifications or tools are required, making it perfect for beginners and experienced rocketeers alike. Durable and Reusable Each adapter is built to withstand repeated use, ensuring you get lasting value. With three adapters in every pack, you’ll always have spares ready to go, making this accessory a dependable addition to your rocketry toolkit. Compatible and Versatile These adapters are tested with Estes metal engine hooks, ensuring reliable performance and secure fitting. Designed for rockets weighing up to 4 ounces, they let you enjoy flights on B and C engines when you’d normally need a C11 or D12, offering more flexibility depending on your launch conditions.
