Ewan,
I've made some good progress the last couple of days- the firewall epoxy is curing to the firewall bearers right now. For servos, I decided to go with DS821 on the rudder and ailerons, with ST47 on the flaps and elevator.
My build thread is here:

A lot of great Unionville Beaver chat here too:
