I too would like to know the recommended control throws. I have the Giles 140 also that AK-Models sells and you are 100% correct when you say the instructions don't tell you much.
I have a Sig 4 star 60 that is almost the same size as this giles and I am planning to start with the recommended throws for it if I cannot find them anywhere else. Here are the recommended throws for the 4 star 60.
Elevator: Low = 3/4" High= 1"
Rudder: Low = 1" High = 1 1/4"
Ailerons: Low = 5/8" High = 7/8"
The 4 star has a 71" wing with 920 sq in wing area and it is a very gentle plane to fly so I think these settings my will be a good place to start.
Thanks
