These are the starting points I use, I am sure others have their own preference but I have found this gives you a safe starting point
Ailerons - 16 - 18 degrees
Elevator 10 - 12 degrees
Rudder 20 degrees
C of G just forward of the center of the wing tube
Engine set up
Make sure you use tygon fuel tube, I use a three line set up, one to fill the tank, one to the engine and one vent line, you will then need a kill switch and a way off operating the choke, a simple push rod that you can reach through the cowl should do
