is it okay to swap with any of my rc cars list, and i don't mind not having the battery , if the thunder tiger eb4 pro s2 is really good and i have bought i for 250, i have used it but not a lot of times and i am trying to get rid of all my rc cars and only have one as i don't have any space or time for the cars. the thunder tiger mta4 is really good and popes wheelies which is fantastic but the only problem is the gearbox and u can sort if out by putting shims in it and some other stuff and it would be alright. or if u cant find any parts for it team associated has make the same rc nitro car and u can buy parts from them. all of my rc cars run and are excellent condition except the thunder tiger mta4, its a really nice nitro car and people i know have converted it to electric, its durable to.
