Update 2/7/19: Checking mail soon for motor screws. I perfected the templates for the custom trainer and slender delta, and started work on the custom trainer. I'm learning a lot as I go. This challenge isn't an endgame for me, or an event so much as a process. Unlike most others entering, I don't have any real success so far with building or flying, so there's no guarantee these will even run well when I maiden. These four planes are more of a learning process where I cut my teeth and practice and learn techniques for the first time that many have already mastered. If they suck and crash the first time, I'll just rebuild and try again.
