JJRC Q60 / WPL Upgrades

thingiverse

I upgraded my JJRC Q60 truck with WPL metal gears and axles that I bought online. Unfortunately, the metal axles required new housings to install properly. So, I designed and printed those first. Then, things started to add up, and now most of my truck is made from 3D prints. Here's what I've done so far: * Front and Rear Axle Housings and Covers * Spring Suspension * Steering Servo Tray * Gearbox Servo Stopper * Chassis Spacer * Axle Lifting Mechanism After redoing the axle housings, I had to rework the suspension too. The original leaf springs kept bending, and the transmission upgrade wouldn't fit without some modifications (I had to space out the axles by a few millimeters). Next, I upgraded my steering servo – maybe it was overkill, but it gets the job done. However, fitting the new servo required removing the cabin seat and floor and adding some mounts for attaching the cabin to the tray. One of the chassis spacers had stripped screw holes, so I designed a new one with tighter holes. As I was prototyping this upgrade, my truck wouldn't turn properly. Initially, I thought it was because of having two rear axles, causing the front wheels to slide sideways. So, I created an axle-lifting mechanism that I later realized wasn't necessary (the problem was caused by a misplaced battery). Now, I'm making this mechanism available for others who might encounter similar issues. My next steps are to improve these parts, design a cover for the battery that blends in with the rest of the truck, and install some lights with custom housings. As always, I've made no permanent changes to the original parts, so it's easy to revert back if needed.
