Ok guys now im really serious about this, i want a truggy for four hundred and under. Now i think i found the one the thunder tiger ttr st-1? Im already talking to hobby shops and they said they would be able to get it. But, is there anything better then it, Like: the xut pro rtr, xtm xst, team vtx truggy, kyosho us sport ready set, mammoth? Now, i will be racing and i want to be competitive and i think the st-1 can do it, but are there others? Also if i buy the st1 is there going to be a new one coming out? Also if i go with the st1 are ther any inexpensive upgrades i need to do? Well thats about it so can you help me out[:-]
