Think snowmobile clutch! That is a cv setup, it uses two seperate clutches connected by a belt. There are different helix, spring, and weight combos for different snowmobiles depending on the weight of the sled and the power being produced as well as what your riding style is and how hard you want it to engage as well as what RPM for it to start engaging. This is pretty much the only way a snowmobile can have a transmission, if you had to let off and shift and hammer on it again it would most likely get you stuck!

There could be potential in designing a system like this for RC but I think it would be better suited to a nitro rather than a BL truck. BL has no problem supplying torque on take off and that is pretty much the whole point of any transmission. The weight that you would save by being able to run a smaller motor would be offset by the weight of the system. Not to mention another tuning aspect, and if you think tuning a nitro motor is hard just try getting one of these set up perfectly! There are all kinds of books on tuning a snowmobile clutch that go way further in d!epth that tuning a nitro motor(if it's hot richen it, if its cold or lacking power lean it out) These clutch setups would be a major PITA!
