Tipping off teeter totter

Rather than cut out this large tree that fell across one of my trails, i free'd a giant 15' splinter that was created by the large fallen tree falling on a smaller fir tree, which became the teeter plank. I then notched the large log to guide the plank, no hardware needed! going on 1 year old. This time i just tipped off it going too slow, and couldn't dab.
