Re: I probably missed it..but..
Each canard has to have an individual servo, which is connected via pushrod: http://www.theregister.co.uk/2014/06/20/vulture_canard_woes/?page=2
The wingtip rudders could conceivably operate off of single servo, but the connections would be a nightmare. There's a single servo mounted in each wing, connected to its respective rudder by a Gold-N-Rod system.
