Quick answer

The Quest Q-Jet C18-6W Value 25-Pack is a smart buy for groups and families who want a reliable, high-performance 18mm motor in bulk. It pairs well with mid-size rockets and offers a long delay for higher flights.

What makes the C18-6W different

The C18-6W is an 18mm composite motor with a total impulse of 18 Newton-seconds and a 6-second delay. That delay is longer than typical for this class, which means it's best for rockets that fly high and need time to deploy the recovery system. If you're flying a lightweight rocket, a shorter delay (like 4 seconds) might be safer to avoid deployment at apogee or on the way down.

Why buy a 25-pack?

A 25-pack makes sense when you have multiple flyers or plan several launch sessions. The per-motor cost is lower than buying individually, and you won't run out mid-afternoon. But it's a big commitment: you need to store them properly (cool, dry place) and you'll be flying the same motor repeatedly, which might not suit those who prefer variety.

Decision rules for the C18-6W 25-pack

  • Choose the 25-pack if: You're organizing a group launch or family outing where multiple flights are planned. The bulk pack ensures you have enough motors for the whole session, and the cost per motor is lower than buying singles. Check your club or family's typical flight count to see if 25 motors is enough or too many.
  • Choose a different motor if: Your rocket is lightweight and flies low. The 6-second delay might be too long, causing the ejection charge to fire after apogee. Opt for a shorter delay motor like the C18-4W or D22-4W for lower flights. Always match the delay to your rocket's estimated altitude—use a delay calculator or previous flight data.
  • Store them properly: Keep the motors in a cool, dry place, away from direct sunlight and moisture. The composite propellant is stable, but proper storage ensures consistent performance and safety. Label the storage box with the purchase date and use the oldest motors first.
