I have updated the reinforced gimbal assembly manual page to reflect the latest changes in it. I decided to make adjustable spring holders a default option (these are really good) and put older ones to Mods directory for the gimbal. Don’t use them unless you have some problems with drilling (like not having a drill, but I would still recommend buying / borrowing one). The provided drill guide tool, used carefully, allowed me to drill as much as 8 holes, still remaining usable after that. I noticed that rinsing the tool with water helps a lot!
