I have done the Superkraft Cap 60, but I did their Cap 232 Sport 60, powered with a 91 2-stroke. I recall that I did wrap 2 oz fiberglass across the firewall and back 2" on the fuselage sides. I don't think I'd trust the stock firewall with a 1.20.

On the pull/pull rudder, that's a good way to go. On the elevator, putting two servos in the tail would give you a major weight and balancing problem. I used a Dave Brown fiberglass pushrod with forked wire at the back end, and that worked just fine.

If you haven't done one of these forked pushrods before, the way I get the wire out the exits is to run outer nyrod through the exits from the back and up into the radio compartment. I then stick the wire into the nyrod, push everything straight back, and presto, the wire slides right out the exits sheathed in the nyrod.
