full throw on a turngy 9x

[cosworth34677]

ok this is a big thing because i think its whats giving me problems with my excavator valves being weak.

i have a flysky9x(same as the many 9x's) and i have all the servo settings at full e.points 120%. but if i take the servo out and put a servo horn on it i looking like it only trurns about 45-60%. am i missing a function that will make them go full throw? if this is understandable please help! im still running the stock program so please no setting that needs the firmware updates or other firmware. thanks .
