6. The elevation gearbox has electronic stops (rectifiers) at the high and low point eliminating the need for a clutch gear system. A nice improvement over the Tamiya elevation unit. No more jerky guns!
I find your statement about this Hooben elevation unit interesting, as I dislike Tamiya's elevation unit..
Could you elaborate some on these "rectifiers"? To my knowledge (which is limited about them), rectifiers are primarily used for converting AC to DC current in electric power supplies. I don't quite understand how these rectifiers are working in the Hooben model. I assume they are reversing the polarity of the DC voltage to the elevation unit's motor when mechanically actuated? Maybe you can enlighten us as to how these things work. I'd like to make my own custom elevation unit at some point in the future.
