I'm sorry I don't get while the Tamiya system is still being held up as the standard, when people are complaining about the flaws in what seems to becoming an out of date system and some of the complainer are Tamiya owners. To use an old system as the standard just seems silly, like a step backwards in a hobby that we all love to see advance forward more. I'm say that ther is any system that is perfect and probably never will be as more people get in to this hobby because every one has different needs and wants. It's like buy a car, they all have different parts taht are not compatable with different makes and models but the manufacturers don't hold a car built in the 80's as todays standard. I think if you have tank on the field and it can fire and take hits from others with out a huge advantage and still fun than that is all that counts.
