Controlling the servos is fairly easy. A single timer can control up
to 10 servos. Each servo gets 2 ms for a 1-2 ms pulse (1 ms = all the
way one direction, 1.5 ms = center, 2 ms = the other endpoint); the
whole thing repeats at 50 Hz = every 20 ms.

As others have suggested relays will be the easiest way to switch
between PIC and manual control. You could use a servo to push a small
switch or button to trigger all of them.

The alternative requires decoding the data from the receiver, which
could take a lot of work if you need to look at too many channels.
If you're brave enough to dig around inside your receiver you can
get the data from all of the channels through a single pin, which
simplifies things. You will still however have a problem if the PIC
crashes/gets confused/etc.
