HPI NITRO RS4 MT RTR $399.99
with Painted Body

The RTR Nitro RS4 MT features ALL of the features of the regular Nitro MT, except that all you do not have to paint and cut out the body. All you need to do is glue the tires, put in AA batteries and fuel, and you're ready to go!
This full-time shaft-driven 4WD truck can handle the most extreme terrain you can imagine! Rocks, dirt, pebbles, twigs, and grass have no effect on the Nitro MT's effectiveness in carving up the worst vacant lot or field! Just fly over them with the all-terrain tires powered by the strong Nitro Star engine included with the kit!

The heart of the Nitro RS4 MT is the 2mm thick purple anodized aluminum countersunk chassis. A strong Nitro Star 15FE engine powers the Nitro MT, providing great acceleration and fast top speeds! The Nitro Star 15FE is one of the easiest-to-tune engines ever, with just one carb adjustment and many improvements made in the past several months for more power and strength!

The Nitro MT is our first shaft-drive vehicle, and we've taken many standard features of other off-road shaft-drive kits and tweaked them with "the HPI touch". The Nitro Star 15FE drives the Nitro MT's spur gear, which transfers power to two dogbones, one to the front and another to the rear. (see the rendering below) The dogbones connect to the gearboxes at each end of the Nitro MT, which contain strong metal bevel gears attached to gear differentials. The differentials give the truck awesome cornering capabilities and great handling!
