humm, ive got a tmaxx that has had a blown moter for 2 yrs. have not had the time or money to fix it, well the way i want that it. ima going to get a .26 motor for it. a new eras chassie and go from there. i need new shocks also, i blew the caps the first time i had it out. never re did them. o well. and as for the cost, well it depends on what you what, batt power or nitro? in the long run nitro will cost more and there is more to clean. batt powered car will cost more up front. still need to be cleaned and you have to wait for the batt to charge. so its always best to have at elast 3 batt packs and a 15 min charger. but i would say look at tower hobbies.
