When I plugged in the flight battery, the rudder went full lock to the right and the right aileron went full up. What the %^&$!!!, it didn't do the Sunday! I started looking at the settings: the timer was wrong, the dual rate and expo settings were wrong, the elevator was reversed, and worse, there was a strange rudder-throttle mix in Mix1 and Mix2. I set everything back right and flew without further problem.

In the heat of the moment those mixes didn't register, but on reflection I realized they looked like the throttle - rudder mixes I use on my P-38 to give some differential throttle control. Checking the P-38 settings confirmed this exactly. The D/R & Expo settings, the timer, and the reversed elevator servo, all normal for that plane, were what had shown up on the Formosa.

So it seems that when the radio battery got to a very low charge state, it lost the settings for the model last flown (Formosa) and grabbed settings from the next model in the list (P-38). I wouldn't have expected this, I would think that at worst it would go back to the defaults. At least those mixes caused obviously wrong control deflections that warned me off before I tried to launch. Has anyone else had anything like this happen?


I'd contact Horizon Hobbies, and talk with their tech department.

I believe those settings would be stored in the DX6i flash memory, and should not be affected by a low battery voltage.

Retired and the days are just too short, busier than ever!
