RC rock crawling is not a fast-paced sport. It isn't about quickness but it is approximately ability and maneuverability -- navigating road blocks and extremely unequal, rocky surfaces that lots of other RCs can't deal with. Although some RC monster vehicles and truggies are designed for rough ground, a specialized school of RC -- rock crawlers -- are made to perform better still on the stones. But if you need any repair, don't go calling a mobile mechanic perth - coz you need a real hobbyist for it.
RC Rock Crawler Characteristics
Although you do not necessarily desire a specialised vehicle -- stock RC monster vehicles are designed for some informal climbing -- increasingly more specialized RCs can be found. There's also a few features that are normal to many RCs used for climbing if they come that way to avoid it of the pack or the features are added when changing monster vehicles or other RCs for rock crawling fun. This list is not designed to be a complete check out RC rock crawlers but it can add a few key characteristics.
Power. For rock crawling you want more manipulated power (torque) alternatively than broadband and high RPMs. Rock crawlers may use stock electric motors and lower equipment setups that deliver stable electricity at low rates of speed to help get right up and over those stones.
High Clearance / Low Centre of Gravity. You do not want your framework dragging in the rocks nevertheless, you also don't want an RC that will word of advice over when climbing a steep rock hill. The top tires on the rock crawler help supply the necessary earth clearance. While you increase that vehicle up high you might wrap up with an RC that tips over too easily so you will want to balance clearance with a minimal middle of gravity. And you will want to be certain the weight is not absolutely all in the trunk where it can draw the RC back again and not let it climb as well. Putting things like the battery to the front of the rear can help with weight distribution instead.
Maneuverability/Steering. Climbing has uneven floors and requires a whole lot of twisting and turning so rock climbers need good tender not stiff suspension system and steering. Most rock climbers shall have 4-steering wheel drive and many have 4-steering wheel steering as well.
4-Wheel Drive - 4-steering wheel steering 's been around in the RC hobby since at least the 1980's (that I understand of). This means that 4 wheels be capable of control what course the vehicle converts. In the event that you were to check out the vehicle ranking over it looking down and flip the front rims left the back tires would be facing right. With the right 4WS installation you can also do aspect stepping or crab walking where all wheels submit the same course.
What 4WS opportunity for RC rock crawlers is an improved ability to go in small areas, overcome the uneven floors, and also have better traction. Among the best RCs growing up was the Tamiya Clod Buster monster vehicle which was prepared with 4-steering wheel steering. Not absolutely all RC rock climbers have 4WS but this is a common feature and one common upgrade.
Unlike other styles of RC driving a vehicle, with RC rock crawlers you will also want locked differentials. Not absolutely all rims are in touch with the bottom or stones at fine times. If not locked, the differentials may send capacity to the wheels that are off the bottom as opposed to the ones that require the energy to overcome the rock.
Traction. Narrower off-road rims and auto tires are normal on rock crawlers. A narrower rim puts more tread on the sidewall and provides rock crawlers better traction all-around because the tires aren't running on a good, even surface as if you find on RC paths -- off-road or on-road. Rock crawler tires routinely have deep, chunky treads and are very soft reasonably. Although you can glue rims and tires, some rock crawlers prefer to use bead-lock rims. Among the advantages would be that the tire doesn't distinguish from the rim easily when put through the strain of rock crawling.
