OMPHOBBY M1 → EVO Upgrade: Full Metal & Carbon Build | English VO

Assembling the OMPHOBBY (Langyu) M1 EVO upgrade kit, step by step, in English voiceover. Four packs of parts, no manual, carbon side plates under 1 mm thick. The official drawing has you bend carbon fibre across an edge — I didn't do that, and I explain the alternative I use instead. Along the way: why the two washers are there, why the kit's screws are shank screws, how tight the blade grips should be so the blades don't slap the airframe at spool-up, and how the metal tail motor mount and tail tube mount fix the parts that used to break in a crash. Bottom line: the EVO kit is mostly about looks — flight performance barely changes. English voiceover with Chinese + English subtitles.
