These rocket engines from Estes come in a variety of sizes but can be easily matched to the recommended engine for your Estes rocket! Due to their hazardous material status, these rocket engines will ONLY ship via the United States Postal Service ground transport. As a result no expedited shipping options are available. Standard delivery can take up to 10 days.
Estes makes selecting the right engine simple by displaying the matched engines on the side of the box or rocket packaging.
