for motorizing the turrets we have to use mini servos due to lack of space, especially for turret dora above the rudder servo/linkage unfortunately most mini servos only rotate 90 degrees, but we need at least 180 degrees (270 degrees would pe perfect) so here's a solution for servo stretching: 2 small potentiometers (5k ohms each) wired in line with the built-in potentiometer, glued onto the servos' bottom now the left/right rotation angle can be adjusted indenpendent from each other, also the center positon can be adjusted properly. max. angle is approx. 200 degrees with notch inside, removing that notch allows up to 270 degrees. servos modified that way can be connected directly to the receiver (with or without slowing module). no microswitches or mini-esc needed, also all turrets are 100% synchronous that way robert v2.0 is already working on a wiring diagram, asked him to post it here... any queries and comments in the same-named thread, please markus

edit: the additional potentiometers should be glued this way for easier adjustment

servos adjusted to 180 degrees (notch NOT removed), slowing module adjusted to slowest speed

Very nice,
i'm glad your way ahead in Germany. So i we can learn from you

the pots' measure in the lower left box is kiloohms, not ohms...sorry the pots' positions shown are just examples, any angle between 90 and 270 degrees can be adjusted. even a different angle to the left or right is possible markus
