Ok, I checked two of my giant warbirds along with my turbine jet. I can not See any variations from the pre Firmware update sub trim setups.
The trim could be off but I would not know for sure until I fly them. I will be flying the two warbirds tomorrow and report back to you with a definitive answer as to weather or not the sub trims were affected or not.
Ma be that only the plane affected is the new one I am now building and just put a new PowerSafe AR20310T receiver in?
I will ask my friend if he has the model backup file.
