Coaster CorporationCoaster Corporation produced a line of model rockets and motors from about 1959 until the company was acquired by Centuri in the early 1960s.
Coaster's original motors did not include a delay or ejection charge. Instead, a fuse was lit when the motor was ignited. After a delay, the fuse set off a black powder charge to deploy the parachute.
Later Coaster motors incorporated a delay and ejection charge.
