The 502I120-15A (I120) is a 58% I 54mm 1-grain reloadable composite motor from Cesaroni Technology Incorporated (CTI).
This motor uses an E-Match igniter.
This reload fits a Pro54-1G motor case.
CTI's Imax propellant is formulated to provide the maximum total impulse for a given motor size. The total impulse of Imax reloads is generally about 10-15% higher than that of any other reload in the same motor hardware. Imax produces a large flame with a slight green tint and dense smoke.
