RE: Official HPI MT2 Thread
GPM parts are made from cast not billet and billet is stronger. All so GPM quality control is not near as good as many others. But if you are happy with them all is good.
Keep in mind the Rush Evo is discontinued and would be a good idea to buy all the extra parts you can get. All so on the Rush make sure you keep the slipper adjusted properly as if you do not will eat up the plastic gear in the transmission. I have an original Rush my self but do not drive it but about once a year as I much rather drive my Hyper 8, Savage or MT.
