help with tekin rs pro bec voltage setting

[szymanski2oo1]

Hi All,

I have an old tekin rs pro esc ..... the servo is running slow with it so need to change the bec voltage to make sure its running on 7.4v .... however is there a way to set that manually on the esc without the hotwire ? I have the hotwire 2.0 .... plugged into an android tablet using the tekin Beta app which is a bit clunky but works .... but it doesnt show the Bec voltage option anywhere to change it.
On the PC software it was easy to find ..... but I dont have a PC anymore. Any help appreciated!
