The Standard Setup Recommendations will work well for those who are not hardcore into rock crawling and don't require the mixing
capabilities provided by a high-end, twin-stick radio control system. The Standard Setup will provide good overall performance and work
well for rock crawling. It is good for those who may already have a 2-channel radio control system and a standard 6 cell, 7.2V battery
pack and charger. Using high-torque, metal-geared servos (minimum 10.0kg/cm @ 6V/140oz/in @ 6V) will ensure solid steering control
and brushed 55 turn Crawler motors and ESCs are affordable and will give you good performance. Using a Y-Harness with an electronic
reverser to join the two steering servos will allow 4-wheel steering. A standard Y-Harness will also be required to join the two ESCs.
Depending on your chosen servo's lead length, you may also require extension leads to connect them to the receiver.
The Pro Setup Recommendations are for those who are looking for the ultimate rock crawler. To take full advantage of the dual motors
and ESCs and the dual steering setup, a high end twin-stick radio control system that features enhanced mixing capabilities should
be used. This will allow for a number of different steering and throttle mixing options that the hardcore rock crawler is looking for.
Using higher torque metal-geared servos (minimum 14.4kg/cm @ 6V/200oz/in @ 6V) will provide the ultimate in steering control
and power. Brushless sensored motors and matching ESCs provide the ultimate in smooth, low end torque. A LiPo battery pack can
be used, or you can use a high-capacity 6 cell battery pack for added weight. Mounting the battery pack over the front axle, or even
splitting the battery pack in two and mounting each half over both axles can be done to optimise weight and traction.
Regardless of the setup chosen, the ESCs should feature a 6V BEC to ensure the most torque to the steering servos. A Y-Harness
battery connector will also be needed to join the two ESCs to the battery pack.
