2 speed tranny

[laton7]

How does a two speed gearbox/tranny work on nitro vehicles? What causes it to change when it does? Are there different types of "gear change" on different vehicles?
Any info is greatly appreciatad thanks guys!

Most use a centrifugal hub setup but there may be other setups I just haven't ever seen them.

All of what I have experience with is a centrifugal slinger type. The slinger arm is spring loaded and the tension of the spring determines when it engages the second gear. Traxxas, HPI savage, Kyosho VoneR, Mugen MTX 3 all use this method. The spring is adjusted (by you) to shift at a certain RPM. Tuning will also effect the shift point.
