Have you set the channel mixing? That may be why you're not getting motion on a servo connected to ch3. There's may not be a signal on that without setting it up.

Correct - Typically steering is CH1 / ESC is CH2.
Plug your 2nd servo into CH3, then read your manual section on Mixes.
CH1 is your Master and CH3 is your slave, activate the mix and adjust the throw of your CH3 slave to match your CH1 master.
