Product Details

Electronic Forward Closure in kit form
Estimated assembly time 20-30 minutes
Some soldering required
THIS ITEM IS SOLD WITHOUT WARRANTY

Motor closure adapters available to fit all AeroTech, Dr. Rocket & Rouse-Tech 29 & 38mm RMS reloadable motors

Features/Benefits:
• Reusable ejection charge ignition device (standard type model
airplane engine glow plug)
• No consumable government-regulated initiators necessary
• Forward burn-through failure mode eliminated
• Integrated ejection charge holder
• Time delay is calculated from rocket motor burnout
• Time delay selectable in one-second increments
• Virtually unlimited time delay range...no compromising delay times
• Short-circuit protection (deliberately short-circuiting the output is
not recommended).
• Light weight, small size
• Long battery life
• Built-in continuity check
• Accidental activation protection
• Reverse polarity protection (inserting the battery backward will
not harm the EFC or fire the glow plug)
• Motor closure adapters available to fit a wide variety of Aero-
Tech, Dr. Rocket™ and Rouse-Tech™ RMS™ motors...new simpler
closure adapter design eliminates the need for two motor
parts (forward delay spacer and delay o-ring)
