Here is a fantastic project that I have found. It is a miniature ESC to use with one of those small RC cars such as a microsizer, or Bit Char, or ZipZap. An ESC is an Electronic Speed Control. It is basically a Motor Controller. I posted previously on using the transmitter and receiver for these cars to build a small airplane. The problem with the receiver is that it won’t support enough current to run larger motors, and it also only has power on or off. This ESC will allow you to change the speed of your motor. It also has a feature that will shut the motor off if there has not been any buttons pressed in the last few seconds. This will save the plane from flying away if it gets out of range. He uses an Atmel AVR Microcontroller, and a Mosfet transistor as the motor controller. Not bad for something smaller than a postage stamp.
The BitESC is a small electronic speed controller for those little RC cars like the MicroSizer / BitChar-G. It can be used in a small RC plane to have some control over the speed of the motor. The speed of the motor ramps up or down, depending on which of the buttons on the transmitter you press. If no button is pressed, the ESC will ramp the throttle down to a stop after a few seconds. This safety net comes in handy when the plane flies out of transmitter reach.
