You say in the FAQ s section that I have to rotate to the left and right the little white thing before fixing it to the servomotor.If I go right and left, then I can t align it with the servomotor.I can t rotate it 180° and then other 90°.I don t want to break it so I didn t push too much.But I think it is not possible to do it, even if I try harder.Before breaking it I would like to know what to do.I hope I didn t receive a broken element in the kit…
Thanks in advance
I got it! 
Hello Maria,
The servos can be moved by had without damaging them, although sometimes it’s a little difficult to do so. It sounds like you figured it out though.
