16 certified hybrid rocket motors from G to K for your flying enjoyment.

Features that we believe make Sky Ripper Systems motors a smart choice to add to your hybrid motor collection:

• Cases constructed of ultra tough anodized 6061 aluminum tubing.
• Easy and reliable pyrotechnic ignition sequence.  Helps keep the ground support requirements to a minimum.
• Snap ring based cases are easy to clean and maintain.  No threads to get damaged by dirt, sand or rough handling.
• Double o-rings on internal components ensure a reliable leak-free performance.
• Universal internal components that work across the motor line.  No need to remember what injector, fill line or nozzle goes to what motor case.  Just change the motor cases to change total impulse.
• A single reload kit for all motors impulses per diameter.  Never be out of a reload for your favorite motor impulse.
• Reload kits that includes preheater grains. Concentrate on flying, not on finding or making ignition supplies.
• Thrust ring is compatible with the complete line of Slimline motor retainers and motor retainer adapters.
• Threaded vent tube port that exits the motor at 90 degrees to the rocket body, not parallel to it.
• 1/4-20 threaded recovery attachment point integrated into the forward bulkhead.  Focus recovery forces on the strongest part of your rocket (38mm,54mm).
• PVC fuel creates tracking smoke during, and after the burn.  Unlike with most other hybrids, you will be able to follow your rocket to apogee on a trail of smoke.(38mm)
• Multiple fuel grain choices for each case gives the flyer great flexibility. (38mm)
