I plan to attempt my first clone, a Big Bertha, and have noticed that the Bertha comes with what appears to be a 9 inch motor mount. I plan to launch on 18m motors and was just wondering if there was a reason for the extended mtm, and if it is necessary.
Oh, and i was also wondering, what is the best material to make centering rings for a rocket such as a Big Bertha? I was planning on using 1/8 Inch Balsa wood.
Thanks for all of your help!!!
