I need to know the rating or specs for the clutch springs that come with the Hyper 7 Pro kit. I've tried searching and surfing but I have not found any info. And are the kyosho 1.1mm springs stiffer than the stock ofna's?? I here alot about the mugen 1.1's but are the kyosho's the same?? Reason for asking is my lhs only has the kyosho springs and I want a stiff spring on my buggy.
