NEWS: Firefly 90, yet another microFPV brushless racer

Seems now we have a huge wave of microbrushless FPV machine, most of them based on minicube/minitower electronics. Here is a the Firefly 90: https://www.banggood.com/Firefly-90-90mm-Mini-FPV-Racing-Drone-PNP-with-F3-10A-BLHELI_S-16_5-Dshot600-5_8G-25MW-40CH-VTX-p-1156924.html. From the specifications, the electronic looks like to the Eachine Minicube with the F3 omnibus FC+Betaflight OSD integrated, the 4-in-1 10A BLheli_S/Dshot600 ESC board. Be aware it’s an ARF proposal … so you will have to add your own favorite receiver. Motors are 1104/7500Kv… All the system should work in 3S. Probably a direct competitor of the DYS ELF 83mm … even if this one is slightly larger and heavier IMHO. The machine weights 63g without the battery and receiver should turn around 90g with. The FPV rig is based on a 25mW 40CH VTX + a 600TVL CMOS camera.
