Annoying but at least it has a timer which many 6 channel sets don't.
I can confirm an earlier reply that if you reset the timer on a DX6i before you power down, it will stay as set, and not become an "up timer". Irritating bug in software. If you power down while it is counting up (or stop it while counting up, and power down), it changes to "up timer" when you power up again. So simply just reset timer before you power down or change models
