It depends on the servo. If it has physical stops on the gears it probably won't go that far. If you want 180 degrees or more get a sail winch servo and use the servomorph to stop it travelling too far. Component shop have some sail winch servos that are about the same size as a standard servo and are cheap. It works smoothly for me.

Well I finally got around to buying a servo morph from the components shop, Installed it in my v+w [rear turret] and it works a treat. Certainley will be getting some more for my next project.
Thanks guy's
Phil

Can I get a demonstration of that?  O0

So this enables a full broadside and can leave the turret there until you center them again?

my solution for Tiger is to use a gear wheel and turret drive from 1/16 scale tank, no wires to worry and it will trav as slow or fast as you want without the need for servos

Well, the turrets from 1/16 tanks (Heng Long being a favorite) have a set speed and so should the warship in question. A slow, lumbering speed would be best. For smaller scales or width concerns in our slender battlecruisers and destroyers, I don't think the retrofitted turret ring from a HL tank, et al, will always fit.

reversible motor with a worm drive to a turret ring maybe (a good worm drive can be found on telescope mounts) motor can be run from a speed controller or a pair of microswitches.

I have one in my 'Dorina' on the 4" turret.
It only rotates about 160 degrees but that might be because it's driving a 1980's 'Sanwa' servo.   Quite smooth.
On my Patrol Boat I used a miniature 'Robbe' 1:500 motor driven by a Mtroniks 10 amp speed control which means it can turn at any speed over 360 degrees.   "Watch out on the Bridge"

Its not the whole turret ring just the gear wheel which fits under deck, on Tiger plenty of room and bearing in mind the 6" turret is mounted well forward

Very good, does what the Technobots one does, but its built. Only does 160 degrees, but has a servo slow down built in too. Got one its great. Didn't respond earlier, too busy slapping my head with my hand repeatedly :-)) Actually, only just looked at the post :embarrassed:
Check out his range...good gear.
