Channel grouping on Futaba works by "grouping" channels 1 to 4, 5 to 8, 
and 10 to 12 into discrete groups which update essentially 
simultaneously. Channels 13 and 14 are simple digital ON/OFF channels. 
So anything connected within one of those 3 4-channel groups get the 
signal at the same time.

So say you had an IMAC/3D planes with 2 aileron servos per surface,  2 
elevator servos (1 per half), and 2 rudder servos plus throttle smoke 
and engine kill (optical kill switch). Your set up might look like this:

CH 1 - Left AIL
CH 2 - Left AIL
CH 3 - Right AIL
CH 4 - Right AIL

CH 5 - Left ELEV 1/2
CH 6 - Right ELEV 1/2
CH 7 - Rudder #1
CH 8 - Rudder #2

CH 9 - Throttle
CH 10 -
CH 11 -
CH 12 -

CH 13 - Kill
CH 14 - Smoke

Or any other combination you might want to get similar servos/surfaces 
grouped together. This is mostly a great benefit when using multiple 
servos on a single surface to stop them from fighting each other and 
causing power issues.
