Frequently Asked Questions

What does F15-6 mean?
"F" is the total-impulse class (40.01–80.00 N·s), "15" is the average thrust in newtons, and "6" is the delay in seconds between burnout and the ejection charge.

Will an F15 fit my 18 mm or 24 mm rocket?
No. The F15 is a 29 mm engine and needs a rocket with a 29 mm engine mount.

Is there a warranty?
Estes warrants its engines against defects in materials or workmanship for one year from purchase. Keep the warranty information that comes in the package. Engines can't be returned by mail.
