You know I could have swore that I started racing with a Kyosho Optima Mid which had an alloy chassis and geared diffs.......
Which makes wonder. Alloy gave way to carbon, which gave way to plastic - so why are we back at alloy again? Its not weight - cars weren't too heavy back then - materials shifted for other reasons.
Likewise the move to ball diffs was for a reason - has that reason gone?
