Cross RC WT-4 Tow Truck Project

   

I've had several Cross RC trucks and I always love them, but when this tow truck was announced I knew it was a bit different.  Tamiya semi trucks (including tow trucks) tend to be 1/14 scale, and Cross RC military trucks tend to be 1/12 scale, but this flatbed tow truck was listed as 1/10 scale.  That means it would actually be usable as a recovery vehicle for my vast array of 1/10 scale RC vehicles.  It also means that this truck is absolutely huge.

This is not a crawler or a trail truck.  It is rear wheel drive with leaf springs and solid axles.  The differential is manually lockable which gives it a little bit of off road capability. It also comes with a lot of features.  It has a full light kit including headlights, markers, tail lights, brake lights, reverse lights, turn signals, dash lights, and even a working light bar.  There is a scale engine and transmission under the hood with the motor inside and a two speed gearbox.  The belts and fan at the front of the engine are motorized.  The bed is motorized to tip and extend remotely.  There is even a working winch at the front of the bed for pulling vehicles on board.  Hood and doors open and latch.  There are real dually wheels on the back.  It uses a metal ladder frame chassis.  I added a diesel sound system.  And finally, it looks really good.

I stuck with the stock 38T brushed motor and a simple but powerful steering servo.  Gearbox shifting is done with a mini servo, and the motors for the flatbed are powered by the BEC.  I I needed all 6 channels of my radio and that still wasn't quite enough.  The truck is plenty fast on either 2s or 3s and has lots of power.
