Hi there, I bought a used Arrma Granite BLX V3 today and I'm having issues with the radio setup. The previous owner replaced the stock setup with a DumboRC X4 transmitter and X6 receiver and didn't correctly set the failsafe. I found a manual for it online that was quite useless and I haven't been able to find a solution online and the previous owner doesn't know how to do it. Can you guys please help me fix this? Currently the failsafe is set to 1/8th forward throttle, I'd prefer to set it to full brake instead to avoid the car running away if it loses the signal.
