Throttled but it goes Reverse?!?!?! [Airtronics MX3S]
So I bought a used Airtronics MX3S locally. I just switched receivers and started to try and configure my SLASH's stock ESC. Everything goes well on the setup. Then when I ran it, my Slash goes reverse. I hit reverse on my transmitter and it does not do anything. I try many times to configure it, and nothing. Steering servo is works too.
I'm new to this radio, any setting I am missing? Thanks.
