Motor KV, prop size and cell count are not independent choices. Here are the scaling relationships that predict current draw, and where they stop being accurate.
One integrated board or six replaceable ESCs? What the six-output format solves, what it costs, and the hybrid layout most builders overlook.
The current figure on a 4-in-1 ESC is a bench number at a specific airflow. Here is how to read the three ratings and size the board to your real build.
Onboard processing is limited by sensor count and logging bandwidth, not by the MCU badge. Here is what each flight controller tier can realistically carry.
Carbon arms fail at stress risers, not by bad luck. Classify the damage, decide repair or replace, then size the new frame to your stack.
Static, blackouts and breakup usually come from the RF chain, not the camera. Diagnose by stage, then match band, power and antenna polarization to the flight.
