If I understood it, they are newbright rc ..

On the servo 1 / 10 NB, there are only 2 wire, which point to the electrical panel .. I think ..

and the servo 1 / 6 NB, there are 6 wire .. (( For the return to center automatically ..))

The servo 1 / 6, can not return to center automatically ..

On the 1 / 6, you will have to serve, the two wire for the motor ..

and that will be welded to the place where the two wire from 1 / 10, are welded ..

I do not think the panel 1 / 10, is in danger, by installing the servo 1 / 6.
