Just got my Flysky a week ago, and have done a couple of “mods” that I have not seen been done by anybody else. (??)
First of I used some (silver for me) paint and filled in the up/dn and +/- on the d-pad, and even if should have been a little bit more careful (used a tooth-stick as a brush) I'm quite happy with the result...
Also, I did not like the way the d-pad / navigation keys sounded and looked. The loud clicking sound makes the transmitter feel cheap (well, it is but you know what I mean
.So when I was adding the back light I used the old foam (the one you remove), to “muffle” the click-sound from the buttons on the controller board.
The pictures explains better than I could.
Just put cut out a bit that is small enough for it to fit when you put the board back, (I had to place the wires to the back light coming out on the left side of the back light) Push the foam gently with the non sticky side on the buttons and you should see exactly were you should make some holes. Use screwdriver to make the holes, and scissors or similar to cut out a little bit extra on the sticky side to fit the actual buttons (do not cut out to much). Do this on both the controller and select-buttons and you will have a d-pad that sounds and feels (to me at least) much better when programming the transmitter.
Maybe someone finds this useful?
Hopefully will flash it tonight.
