Default 3 channel vs. 2 channel?

What are the differences between 2 channel and 3 channel FM radios??

Are TC3 pinions standard pitch or metric pitch?

2 channels means you can control two servos or one ESC, one servo. Three channels means you can control three servos or two servos and one ESC.

TC3 pinions are standard pitch

extra channel lets you control a transmission (ie shifting to reverse on a tmaxx or shifting gears on a nitro sedan (i think))

tc3 is standard 48 pitch, unless it has been changed. It comes 48p from the factory

3rd channel lets you run a fan or personal transponder.

Each function of your car that you control from your radio (steering, throttle, etc) is a channel. You generally need at least two channels (one for steering, one for throttle), and additional channels can be used for things such as shifting a transmission into reverse. As for plugging things into the receiver (PT, Fan), you don't actually have to have a transmitter that is capable of operation that many channels, you just need to have a receiver that has enough open slots; you could have a three channel transmitter with a 5 channel receiver, and, assuming they were both set up for the same frequency, control your car without a problem and have several extra slots to use for accessories like a transponder or fan. (I mention frequency because I think most receivers that have more than 3-4 channels are meant for air use, which would be a different frequency band - correct me if I'm wrong).
