so, following my post here: http://www.diydrones.com/forum/topics/futaba-t7c-channel-5-mode-switch

and the tutorial here: http://diydrones.com/profiles/blogs/configure-6-flight-modes-for

things didnt really didnt seem to fit when trying to set up my radio for six flight modes.  after a couple of days blundering through mixes and comments from other users i finally started to understand what the different settings were doing, and found that half of what i had done was unnecessary.

once i had a clear idea of what changed with each option it was a case of a few minutes getting everything just right.  as promised, a video.
