Connecting Two Servoes On Same Output

Yes, but both will move the same. You can buy Y adaptors for servo cables which do this.

Yes, i want them to move the same.

So, i can solder the cables and them will move both. Is it right?

... You can solder or use a generic "Y" adapter servo cable...

Did you know that you can also control more than one servo from any control in ARC? Press the Multi servo button next to the servo selection when selecting a servo. But yes, it uses more ports. I'm mentioning this, in case you're unaware of the software solution - vs modifying hardware.

Boom, and then he one upped us all , another feature for less work.
