If you are going to but a kit go with a .21 upgrade! You can pick from a long line of .21's and bigger! I have an Ofna .25 in my Maxx and it is just great! Now I am looking into making a dule .25 and just rip up the town! :boxing: I did have to upgrade my tranny tho! It smoked 2 in 2 days! I used Robbinson racing and Golden Horizon for the forward output gear! Now it is bullet proof!
