RealFlight Link with RealFlight Evolution


I've been testing RealFlight Evolution with ArduPilot and so far all is good. I seem to be getting much higher frame rates (approx 2x) which translates to significantly better performance. The semi-lockstep system still works nicely, so I can step through the ArduPilot code with gdb and the aircraft pauses/unpauses correctly.
Are there any changes in the link protocol we can take advantage of? Do we still have the 12 actuator limit?
