RE: SRSG motor power

Hi Paul,

Sure adding drag or more load will cause the motor to lag more. But keep in
mind tat when it lags past a critical point it will just fall out of sync.

Ok, could you increase the lag by increasing the load? Say by putting
something
like paddles in unused electrode holes to increase wind resistance?

Just a thought
