FPV Brushless Motor Eight-Cup Sort Tray
An eight-cup bench tray for FPV and small-robot brushless motors. Each cup has a 32 mm bore that takes 22xx–23xx outrunner bells up to about 31 mm. A 12 mm hole in each cup floor gives the shaft somewhere to sit and lets you push the motor out from below. A 10 mm notch in each rim keeps the phase leads from getting pinched. The whole tray is 152 x 78 x 22 mm.
FPV Stack 30.5 To 20 mm Deck
A 46 mm square, 3.2 mm thick adapter deck that bolts to a frame drilled for the 30.5 x 30.5 mm M3 standoff pattern and carries a 20 x 20 mm M2 flight-controller / ESC stack on four 7 mm posts, lifting it 6.5 mm clear of solder pads and motor wires. A 16 mm centre window passes the battery and ESC leads, two 12 x 3 mm slots take zip ties, and 7 mm scallops in each side edge route wires off the plate; M3 holes are 3.4 mm and M2 bores 2.4 mm so the screws actually drop through.
Dual SMA Bulkhead Antenna Mount
A two-position bulkhead bracket for SMA / RP-SMA panel connectors: two 6.6 mm bores on 24 mm centres through a 4 mm deck, so a standard 6.35 mm bulkhead jack and its nut land flat with the antennas vertical. Gusseted L-frame, 54 x 44 x 44 mm, bolts down through four M4 clearance holes on a 42 x 30 mm pattern, with a pair of 3.2 mm zip-tie slots that take pigtail strain off the connectors — a replacement for the snapped antenna mount on FPV goggles, ground stations and receiver boxes.
