For some reason I always believed Semroc picked up the rights to all the vintage Estes/Centuri designs. It may be more complicated than that, but look at the Mars Snooper, Semroc has the original design, Estes an upscale, and Semroc again with possibly an even larger upscale? Doesn’t matter really, as you said if Estes doesn’t think a particular kit can meet sales goals, then if eRockets/Semroc wants to try and produce a LPR kit, it will still most likely burn Estes motors.
