which one is the best?? I am using M8 with the original rx...
The price is usually the same. The 2123 are 0,06 sec / 60 deg, and the 2143 are 0,08. The 2123 are probably a little stronger too. I got the 2123 myself - I honestly dont know if I can feel the difference, but I choosed the fastest, just to be sure.
7,2 volt servos, can be connected in two ways: either to the FET wire from the ESC or, directly to the battery. The last method is if the ESC aint got a FET wire. The only difference is that you need to solder a coil between the servo and the battery, if your ESC aint got the FET wire.
KO 7,2 volt servos comes with a little manual, that shows how to connect the servo with both methods.
