Dynamite Value of TWIN POWER
Twin Pinions, What's connected? This is where we separate the men from the boys. The RC10-Twin is for serious r/c enthusiasts. Each RC10-Twin is custom built by hand to demanding tolerances. Every attention is paid to every detail. The suspension is tuned to provide the best available handling for the extra weight of an additional motor and control system. The awesome power of having two motors applying power to a single transaxle speaks for itself.
The Birth of an RC10-Twin!The RC10-Twin starts out as a Team Associated RC10T3 Factory Team Built. The RC10-Twin factory technicians skillfully convert the stadium truck to a Twin and tune the suspension. Additional information in the form of a “Twin” guide book is added to the extensive Team Associated documentation. The package is reassembled with the appropriate additional “RC10-Twin” logos ready for ton’s of fun at blistering speeds.
Test Platform(s) - Early TwinsThe early days of the RC10-Twin were filled with excitement and lots of questions, here are just a few;.
So many questions, and, as the development progressed, the answers were every bit as interesting as the questions.

The electronic speed control has revolutionized the R/C car industry. They provide lightning fast response to radio control commands. In some cases they can even charge the battery during a run while braking. They also have their limitations. There is always a limit to the amount of current that will flow through an electronic speed control. This makes using just one speed control on a dual motor R/C a poor choice. Some of the higher end speed controls will work with a Twin but they do not provide enough power for two motors. After all they were designed for single motors.
One alternative that works very well is to use the ESC just as it was designed, that is, one ESC for each motor. Yes, in today’s miniature electronics world it is easy to fit two electronic speed controls in an R/C stadium truck. This works well with the RC10-Twin. Another alternative is the newer speed controls designed for the large Monster Trucks. In this case you will have to use two batteries. I have covered batteries and their configuration in another section.
For the RC10-Twin, a manual speed control, usually looked down upon as inferior for single motor applications, can be a very good choice especially if you are playing around with different voltage batteries. For instance if you were to build a battery pack of 10 sub-c cells the voltage would be 12 volts. This could be a good voltage for some configurations of RC10-Twin dual motors.
Most electronic speed controls do not and can not handle 12 volts but the manual controls do. In the most extreme event you would need to add another resistor or purchase a more powerful one. (they are available)
Some of the mechanical speed controls have as many as a dozen clicks forward and half a dozen in reverse. A little ingenuity to create a good linkage with a fast servo and you have a way to let even the most power hungry pair of motors get all the juice they need from the battery. This is a more temperamental solution to controlling the dual motors of a RC10-Twin but it can also be very rewarding.
Another reason to be RC10-Twin’ing. We get all the best experiments. Isn’t that why we do this sport?
Another tremendous advantage held by a RC10-Twin is the advantage of increased traction on the rear wheels without sacrificing steering traction on the front end. The RC10-Twin has incredible rear traction.
It is easy to take advantage of this phenomenon. We can ad larger tires such as Proline’s “Masher 2000 Monster Truck” tires. These tires are a whopping 4.9 inches in outer diameter. They are a split-V slotted tread design with a relatively soft rubber compound that provide excellent traction. These tires are large but still carry the foam insert and provide an excellent platform for the RC10-Twin dual motors.
When you get the additional power
to the ground by improved traction, Watch OUT! It is going to be lots of fun at blistering speed following a
trenching hole shot! Go ahead, make
the calculations for the jump into hyperspace!
