cooool! you where right. in my place i can easily get my hands on that:
https://www.sparkfun.com/datasheets/Robotics/servo-360_e.pdf (The sm4303R version)..
so i control them the same way as the normal servos?? 1ms pulse, for -180degres and 2ms for +180???
the only problem is its 4.8kg.cm, and i do not really have any idea if this is enough or not.... 
any ideas how i could check that?
