Russia’s capability in manufacturing propellers is quite poor. I have watched many videos of their manufacturing process, and they don’t even perform dynamic balancing. This may not have much impact on small FPV drone propellers, but when producing larger propellers—whether made of wood, fiberglass, or carbon fiber—the lack of dynamic balancing results in a low yield rate, which in turn affects their development of large drones.
A reminder of just how big and powerful Ukrainian “Baba Yaga” heavy drones are is this replacement propellor made by a Russian entrepreneur for salvaged Babas, which are treasured.

Beidou Satellite Positioning System
@BenjaminDEKR Do all those use the US GPS system with a local base station, or are they using something else?

915Mhz is more suitable, with less interference, longer transmission distance with the same power, and better ability to pass through obstacles.
Which frequency band is more commonly used for ExpressLRS—2.4 GHz or 915 MHz? Also, if I want to pick up a transmitter/receiver to put on a drone for testing, any recommendations?

A 10km fiber optic cable kit can cost less than $290
@David_Hambling And the price has dropped significantly since a few months ago. It was around 700$ retail for a 10km coil.
