2019 Crawlmasters VS4-10 Willy’s

ASD Crawlers hosts an event that invites 50 drivers to compete thru challenging gates with your RC truck. This year they added a stipulation that you must run a tire under 4.3” tall and no portals were allowed. I decided to take my Vanquish Products VS4-10 and build a scale truck that was competitive and fun. I documented the full build in Vlog style videos and had a great time at the event, with a final result of 5th place overall. See all the videos below as well as all the specifications on the vehicle. This truck was SOLD in June of 2019 to a collector who promises to continue to use it as it was built.

Build Breakdown:

Base Vehicle: Vanquish Products VS4-10 (VPS09001)

The truck started as a Vanquish Products VS4-10 Origin Limited. While the body, sliders and bumpers were removed, the rest of the truck remained mainly unchanged. The chassis was shortened front and rear and cage work was welded directly to the chassis. The transmission is 100% stock, as are the axles, links, shocks, and driveshafts. The front shock towers are the stock plastic towers while the rears were replaced with tabs that were welded to the cage.

Body: JConcepts Bog Hog

While only the cab of the body remains now, the overall styling of the body was retained and a 3D printed grill was added for some more reasonable styling compared to the included stickers. FreqEskinZ headlight decals were used because the included decals were red since this is based on a fullsize monster/mega truck.
