The Tamiya Tractor Truck series of radio controlled big rigs are available as unassembled kits. You have to build them yourself. It takes a lot of time and patience so these kits are not really for beginners. But if you know and love the big trucks like I do and you have some scale model-building experience they are great examples of radio controlled trailer trucks.

These specs for the King Hauler reflect what most of these big rigs have to offer. The size specs will be different and other features may differ slightly but this gives you an idea of what to expect.

Radio Systems and Other Parts You'll Need:

All of the light, sound, and action functions are done through the radio transmitter. To have all of these options though it would be best to get the recommended 4-channel transmitter. You can opt to have a two-channel transmitter but then you would only have the basic driving functions. The radio and other listed parts must be purchased separately.

Radio: 4-Channel with servo(s). (Or try 4-channel DSM technology (less worry of frequency interference)
Battery: 6-cell flat with standard Tamiya connector
Charger: AC/DC peak charger for 6-cell battery to prevent overcharging
Paint: Polycarbonate for spare body

Tamiya Semi Trailers:

The RC big rigs from Tamiya have several different trailers to choose from. So if you're one of those truck drivers or a wannabe/wish-you-were that used to drive a flat bed, tanker, pole hauler, box container, or refrigerator unit Tamiya has you covered. Most trailers will hitch to any of the 1:14 RC tractor trucks, work with the various option kits such as lights, and have working doors or other parts.

Trailer types include a 3-axled reefer semi-trailer, collapsible pole trailer (with poles), wood-floored flatbed semi-trailer, and a tank semi-trailer with a polished stainless steel tank.

Tamiya RC Tractor Truck Upgrades:

There are so many different upgrades from lights to a little on-board control unit that has a bunch of sound effects (engine revving, alarms, horn) which adds to the realism. The 4-channel transmitter and/or the on-board control unit can control the motorized legs on the trailer (optional), trailer lights, running lights, fog lamps, sounds, and speed indicators. The sound effects are recorded from actual tractor trucks so they are real big rig sounds.

Some upgrades offered by Tamiya are for specific models only but mostly they are for all the Tamiya big rigs.

Modifications and After-Market Parts:

There are a lot of after-market parts and mods that other hobbyist have made public on the Internet which are adaptable to Tamiya's line of big rigs. A lot of them are mostly little things like rotating orange lights for hazard work and little overweight,oversized load signs.
