Decided to start and hoped to finish OK the RC mod I wanted to do for a long time. Many times when I fly, I like to maintain the same forward speed for a long time. DJI did a very good job with the GPS to maintain steady altitude but maintaining same horizontal speed (forward/backwards) is very demanding on the thumb, and speed varies a lot. So, here is the mod, install a pressure blade (like on many other RC as JR or Futaba) to overcome the spring loaded centering stick. Since the left stick is for up/down and center means steady altitude, I have modified the right stick for forward/backwards control. Also I found out why the RC felt a bit loose on the right side, the mounting stem was broken (I guess from the factory since it felt loose from day 1). Upon opening the RC, I was not surprised at how cheap is made inside. Sloppy installation, pinched wires between cards, loose antenna cables, very cheap gimbals without any adjustments for centering stick, soft plastic (but we already know that). At the end I was able to finish the task OK, all functioning good, right stick maintaining position unassisted and along the way fixing the other problems. Here are a few pictures.
