It use to be in good shape , but it went egg shaped , I thought the big end was the one that worked hard ,

that is still on size ,

But I guess the little end is a lot hotter , up near the piston

I used the free machining 2011 grade of aluminium and its done about 20 flights and 2 hard crashes

Im tempted to make one out of a concrete nail I saw down at Magnet Mart , looks pretty tough
