Description
This is my Power Wagon tow truck I built for USTE '21. It is my second RC, and second crawler I have owned as I was just introduced to the hobby in September of 2020. At the heart of this build is a Scaled Out Fab SOF1 chassis with a SCX 10.2 builders kit being the basis of which really only the drive line was used by the time I completed the build. The rear suspension is a modified JS cantilever suspension and all 4 corners are supported by Desert Lizard shocks running mini T springs. The round bits are Gmade SR02 wrapped in Proline Grunts and caped off with SSD hubs in the rear and RC4WD Warn hubs in the front. A Holmes Hobbies Trailmaster Expert and Hobbywing 1080 drive this rig with a Reefs RC 555 giving me powerful but slower and more scale steering action. Both the front and rear winches are Reefs micro 99 servo winches of which the rear is mounted under the flatbed. A castle BEC has been added to stop brown out The flatbed itself was fabricated using nothing more than aluminium L and flat stock from the local hardware store brazed together where possible sanded and polished to mimic a chrome finish. Up front I fabricated the front bumper out of flat and L stock aluminium, finished with automotive paint and clear coat.
During this build I decided that having a 3d printer going to be a gigantic asset to this build and I dove head first into learning Fusion 360 and the world of 3d printing. I sourced files for the dash, windshield wipers, front grille, radiator, sliders, 3d Dode and Power Wagon emblems, and scale items such as the oxy/ acetylene tanks and wheel chocks. I created my own files for my dual front servo mount which also functions as my front body mount and a filler for a gap left when I fit up the 3d printed grille and radiator assembly. The front 99 micro is mounted to a DSM Offroad micro 99 adaptor plate but I created the 90* adaptor brackets between my servo mount and the adaptor plate. I also drew up the battery tray and mounting brackets due to custom size requirements. After a few struggles with PLA considering the structural nature of my printed chassis components I swapped from PLA to PETG and found that it was much better suited for my structural parts.
I never intended for this to be a shelf queen and I certainly have not allowed it to be. It gets regular use these days and despite having built a few other rigs since February this one holds a special place in my heart being my most challenging and built start to finish with virtually no clue what I was doing in a month and a half. It has won two Show and Shine trophies giving me some confidence and motivation to try to outdo myself on the next scale build.
