I have the Teclast F7 Plus for a one month and I already bought it thinking about making this change If you have with heatsink. I even removed all the screws, but I had a lot of difficulty removing the back panel, it looked like it was glued or something. I ended up being afraid to push too hard and gave up, I’ll leave it up to do it in the future, in case of a temperature problem. My f7 plus model appears to be slightly different from the one shown in the video. I wonder if someone had this difficulty removing the rear panel or if this is something of the new models that are coming out?
