Default Futaba 7c

Having problems with my 7c. Intermittently plane will go to idle while flying. Sounds like failsafe, but when get to ground and check battery, it tests fine.
Did replace receiver, still does it. Was doing it on ground last nite every min or so. Was only few ft away so cant believe its a signal problem. Anyone have any ideas..

It's probably the rx battery. Futaba radios will cut the throttle back to idle if they sense low voltage. If you pull the throttle all the way back, it will work again for 30 seconds and do the same thing. That's how you can test for the low voltage idle down.
