Thanks @ Cr0sh and CrossRoads. i don't have transmitter for this car. i played couple days with this board. I followed circus to find out which pins control motor, servo and receive signal from RF. I see pin 1,2 go to Diot to couple mosfets to big mosfet with heatsink. my servo has 6 wires.Green is GND. Blue and Yellow is left or right controlled by pin 13, 14. Red, Orange, and Brown seem like serve break. when server spin to left or right , brown and red or brown and orange are connected.
can i connect pin 1,2,13,14 as forward; backward; left; right to arduino board? if not, can you advice me some things can run mortor? and use servo that comes with arduino kits.
