Speed controls

[chris_theking2000]

Hi, ive got quite an old Tamiya car with a speed control that uses contacts and a servo. Ive been told that i can buy an electric speed control. This would have the heat sink built in and I wouldnt need my servo, the wire from the speed control goes straight to my radio control unit. Is this true? Also would I need any additional wires etc. Please email me with your advice at chris_theking2000@hotmail.com. Any help will be appreciated!

You are correct sir!!!
The ESC and servo just plug into the receiver. Just plug it all in set it up, and have fun!!!

If you get an electronic ESC you can lose the mechanical ESC, the throttle servo and the large resistors. The new ESC will have the heat sink, wires to the battery, wires to the motor, an on/off switch, and a plug that fits in the receiver. The only thing you probably need to consider is how you hook up to your motor. The lower end (read: affordable)ESC's typically have bullet connecters for the motor installed, so you may want to pick up a corresponding set from Trinity to install on your motor. Or you can solder the motor wires directly to the tabs on the motor.

To add on to what RCJunkie said the ESC will typically add to your run time and lower the overall weight of the car. I suggest you buy a copy of the APRIL 2001 issue of RCCA and check out thier Feature called "20 Reversing Speed Controls." Or follow this link: http://www.rccaraction.com/articles/esc_guide.asp
They included a good side bar titled "Why is an ESC better?" that will answer most of your questions.
Also check out this link to thier site also:

I hope this helps.

PS. I love the Futaba ESCs because I have one that is at least 10 years old and works perfectly. The only problem with it is that since it was first made the industry has changed the plug types. The new industry plugs are female connectors and the old way has a male style connectors.
