Better to mount those little buggers now while there are some( and only some) freedom of movement to work from more than one angle, because once the skin is on you´re basically screwed in that department.

I bought 5 pcs microservos from China, typ SG90, 0.8 kg. i ended up spending about 2 hrs before i actually got some good results that i was happy with.

I hooked up the servo to my mousedroids 3rd channel which is a on/off type channel, the result is here below.
