They utilize a patent pending high-strength polymer case and bulkhead, polymer nozzle and RCSs exclusive White Lightning™ aerospace grade composite propellant formulation, which produces a gorgeous bright white flame with lots of smoke and a throaty roar.

Riley H. ★★★★★

The delay on the 7-second ejection charge gave the rocket a nice, high apogee before the chute popped, and both motors in the pack burned with that smooth, consistent composite thrust. No misfires, no fuss—just clean, reliable mid-power flights that put a grin on my face every time.

Riley ★★★★★

First flight with the E20-7W was flawless—the composite propellant gave a clean, steady burn and the 7-second delay popped the chute right at apogee. Two motors in the pack means I already have a backup ready for the next launch day, which is perfect since these single-use units are so easy to load

Ava V. ★★★★★

These motors lit instantly and the 7-second delay gave a clean, textbook deployment right at apogee—no shredded parachutes this time. The composite propellant burns noticeably smoother than black powder, so tracking the flight was effortless.
