Its kinda like the guys say, it all depends on the type of aircraft. and also what you'll need to take into account is the airfoil ,decalage ,incidence on wing and tail. but I agree with the 2 and2 as a start. i got some planes that vary alittle and sometimes alot. for taking off from a runway I tend to use 2 and 2 for handlaunch stuff its mostly just 1 and 1. what I mostly do is set everything andadjust tillmy elev sits level for normal flight
