AeroTech has announced the release of their revolutionary electronic recovery ejection device called the "Electronic Forward Closure™", or EFC™ (part no. EFC-1, $169.95 suggested retail). The EFC is a timer-based electronic recovery system deployment module that attaches to the top of any RMS™-29, 38 or 54mm reloadable rocket motor.

It includes a reusable glow-plug ejection charge ignition system that eliminates the need for electric matches and similar one-time use devices commonly employed with other electronic deployment systems. A robust anodized aluminum housing protects the unit from mechanical shock and exposure to ejection charge residue, and an integral ejection charge holder retains up to 3 grams of black powder.
Easy to set up and use, it was flown at LDRS in Joe Danjou's LOC Minie-Magg™ using an AeroTech H999N-P for propulsion. After a perfect 0.33 second boost and pre-set 8-second time delay, the EFC deployed the parachute at apogee.
The EFC may be programmed to deliver a time delay of one to over 6,000 seconds from motor burnout, in one-second increments. An EFC-1 instructions and specification sheet is available for download in PDF format.  | | Click to enlarge |
New motor forward closures were released that adapt the EFC-1 to the various size high-power RMS motor casings, including an extended version for the long-burn 54mm reloads. - EFC29-1 is the 29mm closure ($24.95),
- EFC38-1 is the 38mm Closure ($39.95),
- EFC54-1 is the standard length 54mm closure ($53.95) and
- EFC54-2 is the extended length 54mm closure ($69.95).
An avionics combo pack (part no. EFC-CP) is also being offered that includes the EFC-1 and one each of all the motor closures for $339.95 suggested retail, a nearly $20 savings. As a bonus feature, all of the EFC motor closures were designed to eliminate the need for the delay o-ring and forward delay spacer, simplifying motor assembly.
Along with the EFC hardware products, AeroTech introduced an ejection charge kit 12-pack (part no. ECK-1, $5.95), which includes 12 each 1.4 gram ejection charges and 1/2" diameter vinyl caps designed to fit the EFC's ejection charge holder.

Technical specifications, motor assembly drawings and instructions for these new reload kits may be viewed and downloaded in PDF format from the AeroTech website.
Finally, new hardware was released for these and other upcoming RMS reload kits. - The 75/1280 case (part no. 7512C, $149.95) and motor (part no. 7512M, $273.95) are intended for several new single-grain 75mm reload kits that will be released later in 2006.
- The 75/7680 case (part no. 7576C, $364.95) and motor (part no. 7576M, $464.95) are designed for use with the M1850W-P motor, also introduced at LDRS-25.
- The 75/7680 case and motor both include a new forward seal disk, which is also available separately (part no. 75FSD, $29.95).
