I am new to the setup of heli's. I have the B400 and stripped 2 of my eflite servos, so i bought 4 hitec hs55 servos. My ? is when i put 1 of the hitec servos on, when i add throttle, the swashplate should move down to give the blades pitch. the hs 55 makes the one side of the swashplate go up, is there a setting in the dx6i to reverse the way the servo turns??? thanks in advance. total noob ????
