The piston just has a little bit of scoring/pitting on the crown from the pieces of the upper bushing. Other than that it's in good shape. The only piece that got destroyed was the upper conrod bushing. If I replaced just the conrod....it would probably be good for quite awhile. If you are interested, I can get some better pics of the piston for you. I was going to keep it as a memento or my very first blown Nitro engine, but it's not a big deal either way.
Here are some pics. I was too close and they came out fuzzy, but you can get a general idea. All these pics were from AFTER the bushing came apart.
All the pics I took can be seen at:
