I understand the principles of bellcranks with buttons for line connection but I have never used or made one before.

So, what material to make a bellcrank for 1/2a proto or mouse racer? Aluminium (6061-T6 or ?) or steel? what material to make the buttons out of? Brass? steel? Minimum dimensions for making loops in the lines are in the rule book, how much bigger is the button made?

Same questions for a .15 size racer or .21 size proto?

Any online resource with details or description (other than the AMA rule book)?

Thanks,

cheers, Graham
