I admit that I am not a RC enthusiast and know nothing about radio control system. I only understand that I require a 6-channel RC system to control the travelling, slewing and cylinders movement. There are large number RC systems available in the market but mainly for remote control of airplane or speed boat models. The 5th and 6th channels normally are switches.
After searching the market, I finally decided to purchase the VEXplorer Transmitter + Receiver Kit. It is a less expensive and simple RC system. It consists of a transmitter with 2 joysticks for 4 channels of control and 2 on-off push-button controls, one receiver for 6-channels with 2 auxiliary powers, and a battery holder.
It is a plug-n-play kit and there is no calibration or adjustment required. You simply insert the VEX 2-pins plugs into the slots of the receiver and change the polarity of the power by flipping over the plug.
Step 1
Connect the motors with 2-pins wires, secure the receiver on the floor inside the excavator model, and inserts the plugs in the slots. Change the polarity of the wires by flipping the plugs if required.
Step 2
As you would not want to dismantle the body of the excavator model every-time you change the batteries, cut out the space under the engine hoop and put the battery holder inside and connect it with the receiver.
Step 3
Stick the control pattern diagram on the transmitter for guidance of controlling the excavator model.
Now you have a complete RC system to control an excavator model. Two sets of on-off push buttons on the top of the transmitter for controlling the forward and backward travel of the two crawlers. Two joy-stick control levers for 4-channels of control. Left joy-stick left-n-right for slewing, and up-n-down for stick in and out. Right joy-stick left-n-right for bucket in and out, up-n-down for boom lower-n-raise.
