Hey guys, newbie here. I bought a DJI Mavic Pro second hand and trying to fix the arm. It is missing the screw from the spring. I tried looking on Amazon / eBay but can't find. It looks like M1 screw, probably 6mm wide head and 5mm or less long. Everywhere I looked there are M1 but only with small heads/tops and couldn't find any washers to combine... I am in UK btw.
