UPDATE 03 JAN 2010: Cameron made his first solo flight today at Mt. Laguna. Conditions were light, and the lift band was out a ways, but he flew about 45 minutes, and greased his first landing!
My 10 year old son is showing some interest in slope flying, so we cut and built this wing. He doesn't have the attention span for long builds, so he was only a part time helper after the spackle and sanding phase.
MAIDEN REPORT: Wing flew well at Parker Mountain on Saturday. Wing performed EXCELLENT! Winds were light, but it still got it going about 78 mph on the backside, and flew on the front side til dark! Fast wing, great inverted performance, great recovery (Thanks Pismo).
