Putting the cart before the horse as I always do, I purchased a 29mm reload casing last weekend, even though I have nothing in which to fly it. I dug through my building box and found enough BT80 tubing and couplers to build an upscale Big Bertha, a rocket with which I have had fantastic luck. Now I need to know how to build a motor mount for a 29, what materials to use for the mount and fins, and generally any info you experienced hands can offer. Any help would be appreciated. Thanx!
