Been attempting some detailing on commanders cupola / hatch and loaders hatch. Access to hand tools and Dremel only so limited as to what I can achieve. Hopefully not too bad.

Hi Andy,Andy Walker wrote: ↑Wed Jun 29, 2022 3:55 pmI've a query about the elevation actuator setup. As supplied the 'piston' appears to have too much travel. Once fitted I think it will continue to travel after the barrel assembly has reached its limit of travel in both directions. Does anyone know if this is the case? If so is there a way to alter/adjust the amount of 'piston' travel. I have tried to do this by adjusting servo travel on transmitter but all this does is slow the speed of the 'piston' down, it doesn't alter travel distance.
It cannot be controlled by servo end points. It is looking for an on off signal in each direction. The only way to limit travel is change the piston or make stops, either in the turret or in the piston itself (much harder). When you use it you can see pretty quick when it's time to stop elevation though.
Hi Andy,
Did you ever get an answer to this or find a solution yourself?

That's a possibility for people that are electrically savvy I suppose. I was considering altering the lever mechanism so that the end travel of actuator corresponded with the end travel of the barrel, but this would severely reduce rate of movement of the barrel. Still pondering options. May just have to leave it as it is.Antony Selwood wrote: ↑Sun Aug 28, 2022 10:04 pmHi Andy,
Just a thought, would it be a good idea to fit an inline fuse in the Actuator wiring?, if the Tx stick is left in the up position too long as you say this could burn out the actuator.

Easiest thing to do is change the THROTTLE lever on your radio so that it self centres.Antony Selwood wrote: ↑Sun Aug 28, 2022 10:04 pm............. if the Tx stick is left in the up position too long as you say this could burn out the actuator.
