3rd build - 2.5" Racing quad. Upgraded BLHeli_S firmware (JESC - 48Hz edition), 220 Ohm resistor on LED pin for camera control, TBS Crossfire RX plus Unify Pro Nano on a TinyLEDs 16x16 board, Caddx Baby Ratel and some 1304 6200KV motors with EMAX Avan Rush props all under 90g without battery. One note on the motors, I had to resolder the motor wires to move them so they lined up with the arms.

Nice! Do you happen to weigh the mini immortal mount and arm protectors? Those look like

the mini immortal mounts weighs .15 grams per and the arm protectors are .3 grams per. I printed them both in PLA but I also had to increase the size of the arm protector by 2% for it to fit. I think the original design was for TPU.

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone!
