For both I would suggest a CG of 30% MAC. Throws and expo are a personal taste thing but for starters you can try 30 degrees on aileron, 15 degrees on elevator and 30 degrees on rudder. Expo can be set to 30% on all surfaces to start but make sure you are going the correct direction. Some radios allow you to go both directions. To verify adjust to 80% and observe the surface has little deflection around center stick and then dial back down to 30. Depending on what you goals are depends on how much throw and expo is used. I fly mainly IMAC with my Extra so throws and expo are set for that..
