Well I did need to be higher. I was at around 100'. It was not a wrong control input problem. My number 2 turn was similar and that was not a problem. I have been practicing for the plane flying at you situation.

As the plane turned towards me I was ready to raise the down wing. I never got to that point. It just abruptly went into the spiral down. Made a nice thud when it hit the ground. I am pretty sure it was a low speed stall during the turn. With the wing banked, the stall speed goes up. I think I was just too slow for the turn, plus too low in altitude. I will have to remember this.

Anyway, starting on a new plane today. Using the tail feathers fron the old and may build a new wing.
