Hi!
Just got my Sabertooth Dual 12A 6V-24V R/C for my kyosho blizzard. It works well and everything. BUT i have this weird issue, when i start using the servo for the plow when im moving my Sabertooth shuts down and it stops, i can still move the servo and when i stop using the plow/Servo and wait around 2 sec i can then start driving it again.
im running it on a 7,4lipo pack so i should be good on power, but can it still be that it kind of get a voltage drop under 6v when using the servo that causes this problem?
“EDIT”: Tried with a 3s lipo with the same results.
here is a video about the problem.
It is much possible that this servo motor is driving too much current and create a voltage drop in your circuit.
What is the specifications of the battery? How much C and what capacity?
EDIT: found my problem and yes it was the servo. I change to a less powerfull one and it worked, well well it sucked that i could not use the more powerfull servo as it is needed. Maybe i can remove the (power) wires from the sabertooth and run a secondary Bec battery
Well, if this motor has really a torque of 14,5KG, this means it is easily drawing near 2-3A which is a lot.
And depending on the peak of your DC motor driven by the Sabertooth, this can put a big load on the battery.
I hope you find a solution to your design.
yes, i saw in the sabertooth manual that it can only drive around 1amp for extra equipment like servos and so on.
I found a solution, the main issue with the original servo was that it had plastic gears, and where i live we easily get -20c its just not a good combo. But i found in one of my boxes of stuff some metal gears that worked so now everything is done.
