dont waste your money on one of those worthless losi's. a couple buddy's of mine have hyper st rtr's. its a very nice truggy for the money. in fact i feel a little stupid for paying a lot more for very little gain compared to the hyper st rtr. the engine that comes with the hyper is more than decent as is the steering sevo (surprisingly).the gas/ brake servo needs replacement as does the tires. the cast hubs break and you should replace them with machined hubs when you get the chance.this is a truggy that really can turn and if you can stay on the gas and keep your momentum then you should be able to mostly keep up even with the ready to run engine.
there is the ebay store, "aatsco" i think who sells the hyper st rtr for $380.00 or best offer. you can talk him down to around $360.00 before shipping . thats a very good deal for what you get. fyi
