Learn how the AeroTech RMS-54 Smoke Only Complete Reload Delay Kit adds a visible smoke trail to high-power rocket flights without an ejection charge.
Quick answer
The AeroTech RMS-54 Smoke Only Complete Reload Delay Kit (CRDK54-S) replaces the standard delay element in compatible 54mm reload motors with a 14-second smoke grain, producing a visible smoke trail during the coast phase without deploying the parachute.
Why use a smoke-only delay instead of a standard delay?
A standard delay element burns to trigger the ejection charge, which deploys recovery. A smoke-only delay replaces that with a grain that burns to produce smoke but does not pressurize the motor tube for ejection. This is useful when you want a visible smoke trail for tracking or effect but plan to recover the rocket using an alternative method like motor ejection from a separate charge or electronic deployment.
Which reload motors is this kit compatible with?
The CRDK54-S is designed for use with specific AeroTech 54mm reload motors: I599N, J1299N, J1799N, K375NW, K480W, K700W, K828FJ, K1275R, K1050W, and L1090W. Always verify that your reload kit is listed on the package or product page before purchasing.
What about ejection charge function?
Because this kit does not include an ejection charge, you must have a separate method to deploy the recovery system. Many flyers use an electronic altimeter or a separate motor ejection charge (e.g., from a second stage or a dedicated charge well). Do not rely on this kit for parachute deployment.
Frequently asked questions
- Does the CRDK54-S include an ejection charge?
- No. The kit contains only the smoke grain, insulators, and spacers (if needed). The ejection charge is not included and must be supplied separately or via an alternative deployment method.
- How long does the smoke burn?
- The smoke grain burns for approximately 14 seconds. This provides a visible trail during the coast phase of the flight.
- Do I need any special tools to install this delay kit?
- No special tools are required beyond what is normally used to assemble AeroTech RMS reload kits. Follow the standard delay installation procedure for your motor case.
- Can I use this kit with any 54mm AeroTech motor?
- Only with the specific reload motors listed on the product page. Using it with an unlisted motor may cause damage or unsafe operation. Always check the compatibility list before purchasing.
