Progress on controller...

Normally,when you power off the dx6i,the screen flashes "saving".
Mine however just switches straight off,as I am using a different switch.
But I managed to isolate the points that trigger the saving,and put a push to break switch on the end plate,so you can save config at any point,without turning off the controller.
It works well and might be a useful feature.Unless you forget to press it after making alot of changes...
I also had problems with the trim switches,which I have replaced with toggles.As the whole stick mechanism was turned upsidown,I had to turn the trims upsidown too,but the visual representation on the display,was doing the opposite,which was really offputting! So I rewired the connections to the pots on the sticks,and everything is ok again.
Just got to sort out what I am going to do about batteries,and rig up a menu system knob,as the original has snapped.
Cheers Jim.
