centering servos

I"m getting the TT today and will need to be centering servos for the first time. I've watched the videos on setting up electronics and have one question. It appears that Josh, in the video has the ESC and Servo plugged into the RX, but no battery connected. Then he uses the trim switches on the radio and moves them side to side. is that all that is to it?

Just wan to make sure I am doing it correctly.

I always just use my transmitter and receiver to center them. Connect your esc to your Rx. Connect your servo/servos, bind your Rx to your Tx. Wiggle your sticks on your remote to make sure the servos move, screw on the servo arm in the orientation you need while plugged up to make sure they don't move. Wiggle sticks again to make sure they are centered. Done. That easy. One thing to look out for tho, make sure your trims on your Tx are centered. lol

Just 1 note. Do not screw in the servo arm while under power. This can potentially strip the servo gearing.

Be sure to disconnect the motor or take the prop off before plugging in the battery to an ESC.

I agree with @Headbang, make sure to unhook the power before tightening the screw. The idea is to get the servo horn on the correct spline on the servo. Potentially, the servo can be mounted at any angle, but you want the horn to be 90 degrees to the surface you are trying to move. Hold the horn as you tighten the screw on the servo to prevent the servo from turning. It's not a big deal if the servo turns, the idea it to minimize the stress on the gears.
