So I have a Futaba 8J radio and I have it working well but one issue I just noticed when testing it out. If I drop the throttle to zero the motors shut down. I know at some point this could cause a crash. Is there a setting that will fix this? I tried a couple but no luck. Please be specific I am not an expert at the RC thing. I don't want to fly until I can resolve this. I am recovering from a crash now.
