Basically when you go into L your servos should be centered to mid stick. You can then calibrate your pitch gauge and put it on the blade (parallel to the boom and the nose and gauge facing straight towards you). The pitch gauge should be reading 0. You will use your aileron stick to move the roll to where the gauge reads 6º of cyclic pitch and you should get a blue status light. If you don't get a blue status light, move the cyclic in the other direction and see if you get a blue light that way. Basically, you are teaching the BX where 6º is and that it is within range that they say is correct.
