RC4WD Trail Finder 2 LWB Trail Truck Build – Part 8 – Electronics

The Build – Part 8
Here we are – the final step! Part 8 of our RC4WD Trail Finder 2 LWB Trail Truck Build has us installing the electronics. We’ll be using a RC4WD Outcry Crawler ESC, RC4WD Brushed 45T Boost 540 Crawler Motor, ProTek RC 2S 4300mAh Shortly LiPo Battery and controlling it all with a Futaba 4PL Radio system. Let’s get to it.

Build Notes:
I won’t be showing you my exact wiring, but you can see a general idea in the following pictures. Use small zip ties to keep everything clean and make sure to keep the wires away from any spinning parts.

Step 1:

The first thing we need to do is install the motor and pinion. I used a pair of M3x8mm FH screws (and countersunk washers) to secure the motor in place.

I used a 14T 32P gear; your setup might vary.

Step 2:

The ESC mounts opposite the shift servo, fitting nicely on the radio pad. The Outcry comes with an external BEC, so I mounted that right next to it. I’ll be replacing the white Tamiya plug with a Deans before I run this rig.

The ProTek shorty pack was used since the BEC took up a bit more space; if you’re not using an external BEC, a standard size will easily fit. Either way, the included Velcro straps kept the battery securely positioned.

Step 3:

I wrangled up all the wires and routed them to the opening in the receiver box. Everything fits nicely, however the box isn’t waterproof; something to keep in mind if you plan on fording any rivers.

Step 4:

Once you get all your wires routed, attach the cover to the radio box. I used a pair of M3x8mm FH screws here as well to secure the lid.

Congratulations – your RC4WD Trail Finder 2 LWB Trail Truck is now ready for the trails! Well, almost. You still need to work paint and assemble the body. Good luck, and hope you enjoyed the build.
