The radio-controlled trucks (rc trucks) are small models, reproduction of real trucks, remotely controlled via a radio remote control.
Initially truck modeling is to reproduce as accurately as possible truck models (carriers or seedlings) but many truck modelers are also interested in construction equipment such as excavators or bulldozers .
Like nautical modeling , this type of model is interested on the one hand in the realism and precision but also in the piloting of the model.
- 1/16: is the scale chosen by the Robbe brand. Robbe trucks are radio controlled.
- 1/15: is the scale used by the famous German brand (officially 1/15, in true 1 / 14.5) Wedico. This manufacturer specializes in rc trucks but has recently introduced 2 construction equipment.
- 1/14: is the scale chosen by Tamiya , the Japanese giant of model making, for its series of trucks rc.
- 1/32: is the scale chosen by Siku, offers different truck rc (dump truck, truck transporter, agricultural tractor …)
Manufacturers of radio controlled trucks
The trucks of Wedico
The German firm is the creator of the concept of truck rc. Their 1:15 scale models are all metal (chassis and cabs) and the bodies are delivered already painted. There are many models of cabins: the European Mercedes-Benz SK and Actros , the MAN F90 , several versions of the Scania CR19, and the Americans like the Peterbilt , and the Freightliner. Mechanical options (improved differentials, wide choice of chassis …), aesthetic (buffalo, chrome parts …) or functional (semi-trailers, trays, tanks …) are available. There are also complex electrical systems that reproduce the lighting and noise of a real truck.
The models proposed by Tamiya are in ABS with the exception of aluminum frame housings and some steel parts. The body is not painted original (except on some models, example MAN GLX).
Tamiya offers four American tractors (three axles including two engines), six European tractors (two axles including one engine) and a carrier. The American models are inspired by existing models but do not display a specific brand with the exception of the Ford Aeromax. The Europeans, on the other hand, are copies of existing models: Scania R470, R620, Volvo FH12, MAN TGX 26. 540 XLX, Mercedes 1838LS and L. To complete the range, several American style trailers are also available as well as some options like the multi functions unit (mfu) which allows to illuminate the whole truck and to endow it with a sound effect in 5W accompanied by vibrations.
These trucks run on a Mabuschi 540 7.2v engine (classic from Tamiya) and have a 3-speed gearbox. They have many details, but are much less flexible than the Wedico.
Tamiya has set up practically unique plugs, specific voltages, so that amateurs can not replace with cheaper products; even of a product of the said mark. For example: the LEDs of a TLU-01 (Tamiya) light kit will not work on the previously mentioned MFU.
It is nevertheless possible to modify them: many parts are sold to improve the performances, to personalize the bodies.
Radio Controlled Construction Machinery
Radio controlled construction machines are reproductions of excavators , bulldozers and dumpers that, like their full size cousins, are capable of performing heavy tasks such as digging the earth. This use requires exceptional power and robustness, which is why these models are all-metal and powered by powerful hydraulic systems. The specialist in the field of miniaturized hydraulics is certainly the German manufacturer Leimbach who, in collaboration with Stahl Modellbau (unfortunately this very popular manufacturer ceased its activity in 2011) made many models. However, Wedico also offers construction equipment: the CAT loader 966G II and the CAT 740 dumper. A new Caterpillar 345 D ME digger was added to the Wedico catalog.
Many model makers who do not find the model of their dreams in the trade, or who want to have a truck or a construction machine more personalized decide to embark on self-construction. It consists of building your own truck, from “raw” materials (plastic, wood, metal …). Here, the scale is only determined by the model maker, who can choose 1/8 as 1/20, although the most used is 1:15. Most of the time, these trucks are based on existing chassis in the trade.
The environment of the RC truck
The truck often moves on a concrete track, or tarmac, like a road. But it also happens that mini-road get together and make special tracks, modular and removable. The road is generally between 50 and 60 cm wide for two lanes of traffic. Can be added buildings such as:
- -The loading and unloading dock: these are often large, open at the top to monitor maneuvers. This is where the different trucks load pallets and other solid goods of different shapes. They are often driven by forklifts .
- -The garage: to stoker trucks during periods of inactivity.
- – The service station: the dummy refueling point for all the trucks and the destination of the tanks.
- -The sand pit: sort of ferry or evolve construction equipment: it is used to transfer materials such as sand …
- Shelters: to store medium-sized materials, fearing rain.
- -Other buildings: for example: bridge, restaurant, house, building … These buildings have mainly a decorative purpose.
