Derek,
There is no servo slow on this channel and yes I’m using the standard SG80 servo. I did have a metal gears version (£4.95) but this unit had a fault and was sent back, so I kept with the standard servo.
The picture of how the rudders servo has been setup is on page one & two of this build log. I’ve used this method/ setup on several of my models and as yet never had a failure or found them to be twitchy.
As for the SG 80 servo, I’ve used these on Rudders, gun rotation and directors on alone of my models and they not give any issues to-date.
As for using servo slow units, On this build I’ve used one on the gun servo. I’d thought I may have had to use one on the helo winch, but the sail winch servo I used is smooth and slow to give a good working operation.
