Quick answer
For most RMS-54 Redline and Mojave Green reloads, the AeroTech CRDK54-02 delay kit provides the 14-second adjustable delay you need—just confirm your motor isn't the I170G or I215R, which use a different delay.
Why the delay kit matters
The delay element controls when the ejection charge fires after motor burnout. Getting the right delay ensures your parachute deploys at the right moment—too early and you risk a hard landing; too late and the rocket may descend too fast.
The CRDK54-02 is designed for use with RMS-54 Redline and Mojave Green reload motors that use the 14-second adjustable delay. This covers most reloads in these propellant lines, but not the I170G and I215R, which have different delay requirements.
Redline vs Mojave Green: what's different
Redline propellant is known for its distinctive red flame and fast burn, which can produce higher thrust and faster liftoff. Mojave Green, on the other hand, offers a green flame and a different burn profile that some modelers prefer for altitude or tracking. The delay kit itself is the same for both—the CRDK54-02—so your choice between these propellants doesn't affect the delay hardware.
The real difference is in the motor's thrust curve and how that interacts with your rocket's weight and flight profile. A fast-burning Redline might need a shorter delay for a light rocket, while a heavier rocket with Mojave Green might benefit from a longer delay to allow more coast time.
Delay kit trade-offs
- Redline for fast burns: If you're flying a light rocket with a Redline reload, the fast burn may produce a quick, high acceleration. You'll likely need a shorter delay to avoid deploying the chute during high speed. Start with the delay suggested in the motor's instructions and adjust based on your rocket's weight.
- Mojave Green for altitude: Mojave Green's burn profile may give a longer thrust phase, which can help a heavier rocket gain altitude. A longer delay might be appropriate to allow more coast time before ejection. Test with the recommended delay and adjust if the rocket arcs over before ejection.
- Check motor compatibility: The CRDK54-02 is not compatible with the I170G and I215R reloads. Always verify your motor's delay requirements before buying a delay kit. Keep a list of your reloads and their delay needs to avoid ordering the wrong kit.
