I used a 20€ EMEK plastic car as base for my RC model
For slowing down RC functions and controlling the car, i chose an cortex M0 32 bit 48Mhz MICROCONTROLLER. It reads up to 6 RC channels does magic to them and outputs 8 Servo signals and 4 DC motors, for all kinds of rotating brushes etc.
The fan is powered by a 30mm brushless EDF with its own ESC.
