While the platform looks the same as any other crawler out there, there are significant differences in it's design that can't be seen. First and foremost is their axles. They use a worm-gear drive instead of the standard ring and pinion. What this means is, when the truck is "off-power", the axles lock solid, equating to no wheelspin. Add to this a disconnect system that does as the name implies, and disconnects the respective axle (either front OR rear) while the remaining axle is still under power. While the concept on it's face doesn't seem to make sense, it allows for extremely tight turns in tight places, called "burn turns". When the turn is completed, flick the axles back into 4WD via the transmitter, and continue on. Many top crawler competitors who don't have a Kyosho Rock Force have modified their crawlers with just such a system, to do just as I described, but with an internal locking mechanism in the transmission to do what the KRF does at the axles.
Another aspect that will escape attention is the linkage system used to connect the axles to the frame. Normally, there are two upper and two lower links that are arranged in a double triangle, to keep everything aligned properly. The KRF uses only one upper link, mounted crosswise in the front, that acts as the alignment for the whole front axle system. Very nice. This also allows the KRF to sit much lower than other crawlers, reducing it's center of gravity, to help keep it on all fours. There also isn't much articulation, but that doesn't seem to hurt it any, as the KRF just scoots up and around anything you point it at, without complaint!
- Shaft driven 4WD chassis designed specifically for rock crawling.
- Large capacity oil shocks are now included on the front and rear.
- 6 mounting positions are available for front shocks and 12 for the rear.
- Wide choice of gear ratio settings.
- Features a 48-pitch first gear and also is compatible with many other gears.
- An optional high-speed gear set (No.RFW002) is available for the worm gear unit.
- Optional rear drive disconnect set (No.RFW001) provides the choice between lock, drive and free running when combined with a 3-channel R/C system. Experiment to find your best technique in controlling the chassis posture for pivot turning and clearing different types of course sections as well as stability coming down steep slopes.
