    Cool OBA Mod and Servo control not working with an NHRA Funny Car

    I've got an NRHA Courtney Force Funny Car and I'm trying to get a Slash OBA system and a second channel 3 servo working with it. I have been able to get audio to come out of the system however my throttle control is not working. I'm also just getting a beeping from the ESC. Is there something strange with the ET-3S ESC that will not allow usage of an OBA system? I also can't get a channel 3 servo working either. I have disconnected the ESC and used an external battery and everything seems to work fine when I do that but as soon as I plug back in the ESC everything stops working. I'm assuming it's because of the built in throttle control for burnout/stage/race mode that is causing the issue and taking over the other channels of the receiver somehow.

    Anyone have any ideas on how I can work around this?
