Hi!
I want to use gear rack kit with a JETI DS-24 radio. I will need to get full travel(9.6") from it. The specs indicate that I will need a higher PWM then the radio will provide (PWM Range to Achieve Full Travel850-2150µs). Is there a controller that I can interface between my RC receiver and the Hitech 785 servo?
Thank you so much in advance for your help!
Hello @marc28 and welcome to the community!
The HS-785HB can rotate just over 8 turns given the proper PWM signal range. With most hobby radio systems the HS-785HB servo range is likely to be just 4 rotations (assuming a 1050-1950usec PWM signal) however when using the servo with a servo controller capable of sending a wider PWM range (Arduino, Raspberry Pi, Pololu Servo Controller, etc.), the servo is able to be driven further without any modifications necessary. But if you want to use your receiver you could add the Servo Travel Tuner (RB-Sct-1272) to your radio system setup and this will allow you to achieve wide PWM signal ranges.
Thanks so much. I will check this out
