Now here's where it starts to get fun. I picked this guy up at the local grocery store for $14 .

I purchased a servo online, the same one that this guy uses
http://www.thedentedhelmet.com/f23/rs-zip-zap-mini-rc-rf-servo-tutorial-25704/ and I wired it up the same way. Basically you remove the control circuit (that uses the yellow wire) and wire the servo motor directly to the receiver board. (5v+ makes the motor turn one way, 5v- makes it turn the other.....just like the wheels of the car go forward and reverse)

That servo operates at 5v so I made sure the vehicle (which contains the receiver board) used the same voltage. 3 batteries @ 1.5v = 4.5v = close enough

(I made the mistake of getting a micro RC car then realized it's motor only operated at 1v.)


Out of the box.

The top popped off easily (2 screws). The battery box is connected to the receiver board and all pulled right out of the chassis in one piece, just had to pull the connectors to the motors.

The receiver board is the top half. Originally I planned to use the unit as is but it was too big so I just removed the receiver board. I eventually went with a 4 AA power supply. I wanted the extra power since I'm running fans, the servo, and the LEDs all off the same supply, and the extra 1.5v isn't enough to fry the board.

The joysticks from the remote control; I foresee them having a future as some sort of greeblie.

Servo mounted

I kept the receiver board in it's cover and mounted it in the helmet right under the servo.

The earcap that holds the RF stalk. I put epoxy around the hole for the RF peg, and I mounted a little switch (might be hard to see) right where the RF stalk comes to a stop. That will turn on the LEDs in the RF topper.

Inside of RF topper, I cut out the little view screen and will put a white LED behind it along with two red LEDs in the front.

That's where I'm at right now. I still need to wire up the RF LEDs and put it all together (a couple of the pictures aren't loading, photobucket is being weird at the moment)
