problem with failsafe on m11x
 

Just picked up my m11x last week and i have the failsafe set as the book says, so the brakes will come on. I have the voltage set at 4.5, but for some reason the failsafe kicks on when voltage is 5.7. I am using the batt. and servos that I have ben and not had any problems like this. MY spektrum was set at 4.0 and that is when it would come on. Cant figure this one one out.
