hi, i looking to upgrade my typhon 3s with bigger pinion...I wonder if anyone uses mugen seiki gears? https://www.amainhobbies.com/mugen-seiki-mod-1-pinion-gear-18t-muge2704/p478943?v=475242 are they as good as robinsin racing one? if the shims are good then it probably shouldn't be any different ... or?
