This should list everything you will need for a complete radio controlled truck setup that is fast, strong, and long lasting for a reasonable price. However, store employees are usually more willing to help you out with problems or with future purchases if you buy through them. You will also need some tools and accessories for assembly such as Phillips and flat head screwdrivers, needle nose pliers, wire cutters, strong soldering iron and solder, X-acto knife, and super glue. Details Truck - A stadium truck was chosen over a buggy because their bigger tires and wider stance gives more ground clearance which makes it easier going over grass and jumping small curbs or other obstacles. Also, their wider stance makes it more stable than the buggies, so you don't flip as easily.
Buggies are lighter and a bit quicker than stadium trucks.
As for choice of truck, the Losi XXT CR would also be an excellent choice, but the RC10T2 was chosen over the XXT CR for durability reasons. Motor - I think machine modified motors are the best for your money. They are only slightly more expensive than stock motors and give so much more features and options. Stock motors use bushings, mod motors use bearings. With a descent battery, you can expect maybe 6-7 minutes of runtime.
