This is an excellent opportunity to clarify a detail. It is my impression that a specific reload kit must be tested in a specific set of hardware (which might be made by the manufacturer of the reload kit - a regular or ordinary certification - or might be made by another manufacturer - a cross-certification). Cross-certifications by class or type, for example ALL CTI 38mm 4 grain I motors, regardless of propellant type, certified for use in AT 4-grain 38mm cases, never took place, nor did the manufacturers intend for such usage to happen. Is this correct?
I ask this because I have recently been doing a lot of certifications of Aerotech Super Thunder single-use and reloads. This is an unusually stout and fast-burning propellant, and as a potential flyer, I would want that specific reload to have been developed and tested for certification in the specific hardware that I planned to use to put in my rocket.
Those of you who know me know that I have not flown a commercially manufactured motor (except for some Estes B4's and C6's) since 2014, but knowing what I know, I would never try to fly the new K1800ST in anything other than an approved 75/2560 case. I want to make it clear that this is not an official Tripoli policy or recommendation, it is my personal opinion ONLY.
