Tamiya F104X1 Build – Part 7 – Electronics

The Build – Part 7
Today’s electronics are super-small and very light. While their placement is not super critical on the performance of the car, we do want them as close to the centerline as possible.

Build Notes:
The F104X1 is considered a pan-car style chassis. Because of this, using thick wire from the ESC to the motor can hinder the movement of the rear pod. I would suggest using nothing bigger than 16g wire. It’s flexible enough and will still transfer plenty of power to the motor.

There isn’t a ton of room under the F1 body. Tidy wires are essential for a nice, clean fit.

Wire up and install the ESC right behind the servo. Hopefully you will be using an ESC with a small footprint. Tape the receiver on the top deck, right in front of the center shock mount.

Install the battery. Since I am using a shorty LiPo pack, it allows me to move the pack forward or back to help with weight transfer and handling. I run the pack approximately 7mm forward of the top deck. Make sure you make your ESC wires long enough to reach this spot or farther back if you move the battery back.

Now the cool trick. Take your electronics mounts and add a small piece of double-sided tape to them, as shown.

Take these mounts and snap them into place onto the top deck standoffs. Since you (hopefully) didn’t grind down into the channel, they will still pop into place. The double-sided tape holds the battery securely in place. To move (or remove) the battery, simply pop the electronics mounts off and slide the battery around. I’ve been running my F104X1 like this for some time and not had any issues with the battery moving or the mounts coming off.
