Read about RC Crawler Vehicles HereAn RC crawler, in case you didn’t know, is a kind of mutant RC vehicle. It’s made from a truck body and designed to creep over steep inclines and declines, and negotiate impossible looking piles of rocks to get from one point to another.They can be scale vehicles with incredible details, semi-scale trucks with competition performance in a scale-appearance package, and all out competition rigs that may look gnarly, but seem able to crawl nearly upside down. If you’re a slash and burn kind of driver, you may have trouble with a remote control rock crawler, where driving finesse ranks high and speed is measured in fractions. To get a good start in this addictive RC action, you can purchase a RTR 4x4 RC truck from any hobby store, retailer or internet source advertising them. If you wonder what the difference is between the monster-truck-4x4 you’ve brought home, and an RC crawler, the answer is fairly straightforward. RC rock crawlers: •Have full-time 4 wheel drive •Have locked differentials •Have a stretched wheelbase, usually 12-12.5 inches •Have large tires with foam inserts, often trimmed to rock-gripping shapes •Have a very low center of gravity (CG) If you want to dive straight into building your own remote control rock crawler, there are excellent kits available, such as the Axial AX10 Scorpion rock crawler kit. These kits give a newcomer a head start and lets you get out and crawling after just a few hours of building. Kits normally include: •Axles •Chassis •Shocks, Links and Driveshaft •Transmission •Body, Tires and Wheels If you want to morph your big rig clod buster, there are reputable parts providers that make putting together an upgraded vehicle less of a nightmare. Some tips to keep in mind while building or tweaking your remote vehicle: •Make use of quick disconnects – makes digging into your RC crawler to find problems much easier •Set your tires up to run with the tread reversed •Add weight to the front tires – stick-on weights or BB’s are the norm •Mount shocks upside down – lowers the CG •Use a rounded body style – your rig will be more likely to flip back upright after loosing footing •Lock differentials with JB Weld or hot glue – for best security, order machined aluminium lockers •Load your tires with foam – try the new memory foam inserts from KreepyKrawler Design •Get the best radio you can – pistol grip models can limit your response – find a radio that allows you to do ‘2 stick’ steering, front and rear •Don’t skimp on servos – you need power to crawl Patience is the name of the game with a remote control rock crawler and new tricks and tips are constantly coming up as new parts become available and innovative RC enthusiasts have new brainstorms. Organized groups of RC rock crawlers are everywhere and regularly get together for competitions and to swap ideas and ogle each other’s crawlers. Going slow was never so good!
