Does anyone know how to change the position of a servo when using a failsafe device? I want my servo to run anticlockwise, but it doesn't. Some other larger servos, seem to go clockwise.
I was using an old Subtech APC. Nothing wrong with it! It WAS working fine, until I had to change out the ballast servo in my Gato.
I also had an Mtroniks failsafe and all was well. The problem arose when I discovered the new servo was working in the opposite direction when the failsafe operated them. So I got a 'vent' instead of 'blow'. Not good!
I couldn't turn the servo around as the space was very confined and designed to accept the servo one way only.
Anyhow, I changed out the APC & Mtroniks Failsafe for Kevin McLeod's ADF
I simply connected the servo to the lower pins on the ADF then tweaked the lower adjuster screw until the servo was in the proper blow position.
Works like a charm!
I'm not very good at this stuff, and generally struggle with R/C, so I ws really puzzled to find servos kick one way or another. I thought perhaps they had a memory that could change, but thankfully they aren't that complicated!
Anyhow! All is well, and I think I may be back in the pond tomorrow!
Are you perhaps referring to the SubTech SubSafe? The APC, being a pitch controller, wouldn't be expected to drive the servo to a preset position when the transmitter signal is lost.....!?!
The SubSafe has an adjustment pot on it that is used to move the servo into the desired position upon loss of signal........
No, I was using the Subtech APC-4 pitch controller with an Mtroniks Failsafe.
As far as I can tell, there is no way to make any adjustment on the servo once the failsafe kicks in using this configuration.
The ADF however, is a combination of both leveller and failsafe and CAN be adjusted to tweak the servo.
Rather than waste a perfectly good APC, I'll just put it in a boat where I can switch the servo around - I think! Of course, Sod's Law will prevail when I come to do that! Isn't all this fun!
Open up the servo case, swap around the outer two leads of the feedback potentiometer, and also swap around the motor wires. Your servo will then operater correctly.
