Bowlman:

Before they mentioned that its a common Spektrum problem, it sounded ~so~ much like a Tamiya Mode 1/Mode 2 issue. Most of the new models that can be used for aircraft use have this switch, as some prefer throttle on one side, some on the other. This allows the channels to be swapped at the flick of a switch.

And YES, this is why the Tamiya DMD Manual plug-in instrictions are off... they wrote the manual to set up in Euro Mode, and we're more used to the other mode... (canna remember which is which, and too lazy to look it up) I pointed this out AGES ago over in the Armor Hut, but its WAY back...

Wonder if this is part of the reason for the Spektrum glitch, summat to do with when it overdraws, it tosses the programming and it swaps modes... anyone dare to ask?
