I've got my server arm so that it is not square with the server case. It is swept back slightly. This matches up with the snake (ie. straight in out rather than tugging it away from the balsa block that it is glued to) and as the stick is moved, there always seems to be proportional movement at the engine end. However, if I make it square with the servo case then I get what the guy warned against, not a full range of movement at the engine end (ie. the last bit is side to side at the servo end so there is no change at the engine end). Does it matter where the arm is if the movement at the engine end always reflects the stick movement ?

Thanks
