rookesy...i started to control the 4 wire servo just like a normal dc motor... i connected the phase wire (red) to +V and grounded the black wire..it started to spindel clockwise, you can control it easy with L292D or H-bridge transistors (clockwise and counterclockwise), you can divide the inputs in small delay with the arduino (maybe 10 milliseconds) and control the position by counting it.... but what i am asking is if it can be control as a servo and not like a dc motor...the servo has more torque since it always want to remain to that degree, that's why i have open this topic...........or maybe we can both apply some gear reduction or gear system..but that is another thing
