Just finishing the fins of the 4" version. The 3" version is several sequences behind to allow improvements / lessons learned from the former to be incorporated. (Weight is the critical issue with the 3", as I am trying to fly it with Level 0 motors. On the 4", I can just pile on Newtons to make up for my lack of building skills. Vmax is my friend.)
