Due to Covid-19 I have been unable to launch using a CTI L645 that I loaded into its 75mm motor casing many months ago. I'm wondering if the forward and rear closure o-rings will "relax" and take a "set" thereby offering considerably less sealing properties. O rings were greased with synthetic grease. Usually I launch within hours of loading up.
