Straight buddy link works with dx7 as slave.
Plink doesn't. Many channels are reversed when transferred to dx7,and twin servo ailerons right is lost. Changes to program in the dx7 such as reversing are ignored. If I bind the dx7 to the model it works correctly.
It seems you need 2 identical txts for p link to work. Not what I had been led to believe.
I think the wot4 will be too difficult for my son with all the channels at once. I'll start with my zafira glider I think.
