Quick answer
Choose the AeroTech RMS-75 No Smoke Charge Forward Closure when you need a plugged forward closure for the 75mm RMS hardware, specifically for use with the N2700W-PS reload kit that suppresses the tracking smoke charge.
What is a plugged forward closure?
A plugged forward closure seals the forward end of a reloadable motor casing, preventing ejection charge gasses from escaping forward. This is typical in high-power rockets that use electronic deployment or when the motor is mounted in a booster stage where no forward ejection is desired.
Why choose the No Smoke Charge version?
Standard forward closures include a smoke charge compartment for visual tracking. The "No Smoke Charge" variant omits that compartment, reducing weight and complexity. It is required when using reload kits like the AeroTech N2700W-PS that are specifically designed without a smoke charge.
Compatibility and fit
This closure is designed for the AeroTech RMS-75/10240 motor casing. It is not compatible with smaller 54mm or 38mm hardware. The threaded design allows secure attachment to the casing forward closure threads.
Decision rules for choosing this closure
- Motor casing size: Only use this closure with the AeroTech RMS-75/10240 motor casing (75mm diameter). It will not fit smaller hardware. Check your motor casing diameter before purchase.
- Reload kit requirement: This closure is designed for reload kits that specify "No Smoke Charge" — such as the N2700W-PS. Using it with a standard reload may leave the smoke charge compartment unused but functional. Verify your reload kit's description includes 'no smoke charge'.
- Deployment method: Choose this closure if you rely on electronic deployment (e.g., altimeter) rather than motor ejection. The plugged design prevents forward ejection gasses.
