- The F405 V4 is the FC half of the SpeedyBee F405 V4 30×30 stack.
- The file is a 41.6 × 39.4 × 7.8 mm block with four Ø4 holes on the 30.5 mm square; the board outline is not rectangular in reality and connector positions are not modelled.
- The pattern is assumed centred on the published board size, since an offset is not published.
- True size, no printing tolerance added. Only published numbers are used; anything not published is said so.
- Secondary source: the numbers come from a retailer or magazine copy of the maker's specification.
