RC Rock Crawlers

Saturday, August 15th, 2009

rcrockcrawlerAs long as there have been cars and trucks, there have been toys modeled after them. Whether its putting together your own model car or getting involved in various types of remote controlled devices, experimenting with miniature trucks and cars is more than just a hobby for some people. Indeed, it is not unusual for people to become enthralled with these types of things, and RC Rock Crawlers are just one really good example of this phenomenon.

RC (remote controlled) cars and trucks are undoubtedly popular. Traditionally, many remote controlled cars have been highly prized for their speed and their ability to race around sharp curves and around homemade courses and tracks. However, RC Rock Crawlers are entirely different and, some would say, more entertaining to experiment with. That is because, unlike other kinds of remote controlled cars, RC Rock Crawlers are the all terrain vehicles of the remote control world.

With RC Rock Crawlers, you do not need to supply a smooth driving surface in order to enjoy them. In fact, you want to give the rugged terrain to test their skills at! The possibilities are truly endless with these kinds of vehicles, and it is little wonder that so many people become such huge fans of RC Rock Crawlers. Many of them are available already assembled and ready to go; others are designed from scratch or custom designed to be able to handle rough terrain.

The type of RC Rock Crawler that you end up purchasing depends a lot on your skill level, and whether or not you want to put one together. Purists would say that designing your own is the absolute only way to go; it allows you total control over its components and can give you the opportunity to create RC Rock Crawlers that go above and beyond anything that you can find already assembled at a typical store.

There are two main, necessary components to RC Rock Crawlers - power and maneuverability. These trucks must be designed incorporating both of these. Beyond that, the individual traits are highly customizable. However, if you are just beginning to learn about RC Rock Crawlers, you might find the following list useful in determining what kinds of characteristics are the most important to you.

Power: When it comes to RC Rock Crawlers, power (or torque) is far more important than the ability to get up to very high speeds. These types of vehicles generally use lower gears that allow them to easily travel over rocky, uneven terrain.

Clearance & Center Of Gravity: RC Rock Crawlers need to be high enough off the ground to easily pass over rocky outcrops and other obstacles. But at the same time, they should be able to handle the motion and not tip over when put at steep inclines. An RC Rock Crawlers will therefore have very large tires to give it good clearance. Weight will be evenly distributed so that its center of gravity isn’t too low, causing it to tip over frequently.

Maneuverability: The steering and suspension on RC Rock Crawlers needs to be soft, not stiff. This way, they can make the frequent turns and twists necessary to handle rough courses and terrain. Four wheel drive, as well as four wheel steering, are common on RC Rock Crawlers to give them more accurate steering capabilities.

Traction: Since RC Rock Crawlers have to climb steep surfaces and sometimes slippery rocks and boulders, their tires must have excellent traction. The rims and tires will need to be narrower for these machines, employing off road characteristics. This way, your RC Rock Crawler can easily handle just about any terrain that comes in its path.

Axial AX-10 Scorpion

axial-ax10-scorpion-rock-crawlerThe Axial AX10 Scorpion Kit is a 1/10 scale, 4WD Electric RC Rock Crawler. This is the first RC Crawler of its kind as its built from the factory as a performance level competition base kit. Previously the only way to build a competition capable rock crawler was to buy bits and pieces of several different kits here’n'there. This long and sometimes frustrating process would take as long as several months just to get the right parts together before you could even start the build. Now you can get everything in one box, and within a matter of a few hours build-time you’ll be able to hit the rocks with your competition ready AX10 Scorpion Rock Crawler!

Axles:
The axles have been designed with many features that are not available from other products on the market.  Everything from the axle strength, pinion angle, caster, and ground clearance were taken into consideration when designing these axles. The result is a far superior axle that will stand-up to some severe punishment. To ensure added longevity from the start an aluminum diff locker is included along with hardened drive shafts.

Chassis:
The AX10 Scorpion chassis is lightweight and stiff.  Twin 2.5mm aluminum side plates are tied together with aluminum posts that create a rigid structure. The molded nylon skid/transmission plate is designed not only to be strong, but it’s radiused edges aid in preventing hang-up’s on jagged surfaces. Additional design features include channeled grooves which assist in directional stability. Scale was also taken into consideration, and the chassis was made as small and compact as possible to cut weight as much as possible.  A simple, yet highly functional battery/radio tray makes installation of your electronics quick and easy.  Wheel base is adjustable from 304mm ~ 320mm.

Transmission:
The AX10 Scorpion transmission was designed to place the weight of the motor as low as possible to maintain a low CG (Center of Gravity). The ultra compact transmission doesn’t compromise performance because it also allows for a wide range of gearing choices.  The overall ratio can be adjusted from 15:1 all the way up to 74:1 using different pinion/spur gear choices which allows for super high speed or to competition level crawling speed.  The transmission is locked with no differential action which allows for both wheels to get the maximum amount of traction. The out-drive shafts come in a hard anodized aluminum for added durability.
