These reloads fill a unique niche in the model rocket propulsion market as they are intended for use in rocket powered gliders and land vehicles only. They are generally designed to produce long-burning thrust profiles to minimized flight stress on lightweight glider airframes.

The D7-RCT is designed to fit the 24mm diameter AeroTech RMS-R/C 24/20-40 reloadable motor case, which has the sam physical dimensions as the black powder D motor, but delivers up to 2-1/2 the total impulse.

Since RMS-R/C reload kits do not include a delay or ejection charge, they should not be used in standard model rocket vehicles unless equipped with a timer, altimeter or radio-activated recovery system.
