Alternate to eCCPM 120, you can also go for eCCPM 90 if u want.
My TRex 450 is eCCPM 90 but using only 3 servos. Reason I choose eCCPM 90 is because it is easier to construct onboard eCCPM.

yes 100oz is more than sufficient for any sort of triangulated CCPM.

The only time servo strength would have any question for CCPM is with 90° CCPM. For this setup, the two lateral servos are 180° apart on either side. Any elevator movement is isolated to the single forward servo. My e620 is like this, and I have absolutely no problem with elevator control since I'm using 9451's on 6v (127oz each). This is still overkill, but they're fast at .10 sec.

Have you got 2 servos on 'aileron' and 1 servo on the 'elevator'?

I would have 2 on ele and 1 on aileron. Helis always seem to flip faster about the aileron axis than the ele.

I know full-size helis with 90' 'swashplate mixing' have 2 hydraulics on aileron and only 1 on ele but then thats for different reasons.

My eCCPM 90 is 2 on aileron and one elevator. Why I choose that way is because it is easier to mod with only one elevator servo. 2 elevator servo require me to find a way to mount the frontal servo somewhere.

As for flipping aileron faster than elevator, it maybe because for elevator, the heli need to lift the tail during flip. Lifting tail is slower than flipping sideway.

For full size heli, may I know what is the reason they use one hydraulic on elevator?

They make several corrections-a-second on aileron but hardly touch the 'elevator' in forward flight.
