The radio allows you to program a percentage of spoileron and flaperon when the switch is used. (i.e. 50% travel for spoilerons and 60% travel for flaperons. which is what I've programed in to start with) The ailerons also still work as normal, just from a lower or higher point depending on which one is selected. I also agree that linking the spoilerons and flaperon to the elevator in a proportional way would be better, however my radio doesn't allow for this. I just though that some spoileron and flaperon would be better than none. Espeacially the spoilerons as the fazer is very hard to stall, which makes elevators hard to do. I think once the spoileron or flaperon is selected and the correct initial elevator trim required is programed into these functions, (through trail and error) Pulling in more or less elevator will only effect the pitch of the aircraft. But only time will tell, as i haven't yet flown with these functions.
