Just finished up the Estes version of the sounding rocket. I've been working on it simultaneously with a Wildman Gizmo XL (which could used as a tire changing stand on heavy equipment its so beefy). The kit is "advanced" but golly gee those decals sure require a steady hand. I've said it before, small rockets are almost a completely different hobby than big high power ones. End result is a rocket but the road there is very different. Hence I like to indulge myself on micromaxx, low power, mid, and high power... Often times simultaneously!
