FPV ideas that quietly disappeared (and might deserve a comeback)
Oscar Liang just put up a fun list of FPV trends that never went mainstream, and reading it felt like a trip through the hobby's history. His point is that disappearing does not mean an idea was bad. Sometimes the technology simply went another way, or a cheaper solution won.
Take angled motor mounts from around 2014 and 2015. Wedges under the motors tilted them forward so the quad did not have to pitch as far at speed, which could also cut drag. Frames got lighter and pilots simply got used to steep camera angles, so the extra hardware stopped being worth it. Custom PDB bottom plates for frames like the ZMR250 made builds very clean, but they only fit a handful of frames, and modern FCs and 4-in-1 ESCs already integrate most of that.
Soft-mounted motors were a big topic around 2017, when gyro noise was a real worry. They added weight and loose screws, and what really ended them was FC makers soft-mounting the gyro or the whole board, plus much better filtering in Betaflight. Nylon standoffs were meant to act as mechanical fuses in a crash, but they sometimes snapped in minor tumbles, so metal won.
My favourite from the list is the Chickadee Polystack from 2016, a stackable, open-source modular flight controller where you add only the modules you need, almost like Lego. It lost out because modules cost money and space while ordinary FCs kept adding OSD, BEC, blackbox memory and more UARTs on one cheap board. The list also covers 3D stereoscopic FPV cameras, servo-tilting arms, 16x16mm stacks and 4 to 6-blade props on 5-inch quads.
Personally, I found the modular FC idea the most interesting one to revisit, even if the economics never worked out.
