Hello all,
I am new to this forum but not to rocketry, albeit with a 42 or so year gap. As a tip of the hat to some of my earliest rocket builds in the late 60's I am scratch building a few Estes designs, one being the Big Bertha. I am curious if anyone knows when Vern's Big Berth design evolved from his original plan as published in the Estes newsletter (and the early kit version) to the revised design where the original (short) engine holder is replaced by a much longer holder assembly, no doubt to improve pressurization of the parachute compartment. There is an article posted on line detailing the evolution of Bertha but I didn't notice any mention of this change. So if any of you have any thoughts please share them. I'm just curious.
Thx, Tom H.
PS: Anyone aware of any rocket clubs in the Western MA - Northern CT area? I'm getting the notion that now that pot is legal in MA They are attaining a different "high" and watching the lawn weeds grow....
