I had thought that maybe a sudden tail wind had reversed the effective

anyone with more experience on an aircraft like the B-4?

You had probably just barely reached flying speed. When you deflect an
aileron, it increases the effective angle of attack of that wing. The
tip probably stalled, and since the other wing was still flying, the tip
you were trying to pick up, instead dropped to the ground. The lesson
you should learn from this is that until you are at a reasonable speed
(i.e., able to pick up the tail and roll on the mainwheel), use opposite
rudder to pick up a dropping wing tip, not aileron...
