I use to run electric had arrma kraton and typhone I could turn up the servo voltage on them Wich made servo much better . Now I have a HPI nitro with TF-1 controller does anyone know if I can turn up my steering servo voltage
I have 2 Arrma vehicles and have been into RC for almost 40 years. I have never seen a radio you can turn up the voltage for a servo with. Do you mean the dusl rate knob?
Otherwise, you need a BEC wired into your setup to adjust servo voltage.
I recommend upgrading to 2.4ghz ASAP. AM gets a lot of interference with nitros the most in my experience. I'm running a Radiolink RC6GS V2 which can have up to 10 receivers bound to it. The Flysky GT5 is also a great choice. For the servo voltage, you'll need an external BEC for that.
