Just a "fun" tale about my PT-40 (you do fly a PT-40, don't you, Zister?).

On take-off a few months back, the nose wheel hit a particularly stubborn tuft of grass (I fly off a grass field that has a coarse grass). The wheel bent back on the spring so far, that it re-bounded into the prop. The APC Prop put two neat slices right through the Du-bro rubber wheel (It fortunately missed the wheel-hub).

Lesson: props spin fast and hard, and check yur nose-wheel for slices....

I had no spare wheels, so I glued the rubber together with medium CA, and flew some more. About two weeks later, same thing happened. Two more slices on opposite side of wheel. Bit freaky. Hasn't happened since.
