F15-4 Engines (29 mm)

You have always had good service when I reached out to you, but this time you responded within 15 minutes and 35 minutes later my motors were on the way. The issue was resolved. Thank you very much!!

4 years, I've been enjoying the quality of rocket engines, great quality. Good company, good prices.

Estes F15 engines are perfect for giving my mid-power models slow off the pad, powerful, realistic flights. Lots of lovely smoke and plenty of altitude. I buy them by the box!
