RE: Seiko PS-050 servo battery - which one ?
I might solder 3 servo leads onto the power leads from the Seiko servo, and then plug these servo leads into three spare ports on the rx.
This should supply enough current flow.
I'm just trying to avoid the use of another battery and another switch just for the Seiko servo, especially when I know the A123's will provide plenty of current flow for everything.
I'm always looking for ways to save weight.
