I’m determined to get some Autel Evo content on to this forum 
First mod, well, second, first mod was the CS bracket but I’ll post about that one another day.
Button Bumpers!
Just some 3D printed rings really 
They come with a strip of sticky tape that you have to cut to shape yourself (hence me not recommending this seller):
Once the sticky stuff is cut to shape you simply stick them over the A-B buttons on the back of the controller to prevent accidental presses.
Why would that be an issue?
Because for some reason, these buttons are not yet user-definable and pressing one of them (I forget which) by accident launches an Alexa-style voice command process where you can verbally tell your drone to RTH and stuff 
Anyway, there’s light at the end of that programmable-button tunnel as the new instruction manual that came out with the new firmware the other day says:
More Evo mods as they happen!
