Best Overall Truck...
The best truck at the track bone stock is a Dominator. Tmaxx and Dom are pretty close top speed but the Dominator is alot more durable out of the box. Also a ton of upgrades out there. Tmaxx is prolly more user friendly for beginners tho.
If ya want to go cheap get a Monster Pirate. Biggest differance between them is a bit smaller tires and lack of a slipper.
Alot of the new trucks are too heavy out of the box for racing. It can be done with anything but lighter weight is going to handle much better and have a bit more punch off the line. Although with 2.5 hp the differance isnt as big off the line as some would have you think.
