I'm trying to use up some older motors and have an H238T-M (10 second delay) that I'd like to increase the delay on to use for motor backup ejection. I'm expecting apogee at 11.4 seconds, so would love to change it in to an -L. I know I can buy an RDK-06 and make it an -L (14 seconds), but I also have an extra delay grain from an H128W-M from a previous swap. Given that the H238T-M (10 seconds) delay is .469" long, and the H128W-M grain is .563" long, and the RDK-06 (14 seconds) is .594" long, is it safe to say I'd get about 13 seconds of delay? My other option is to just let the electronics do their thing and not put any ejection charge in the motor, but this seems like a pretty good way to get a redundant backup.
