Understanding of telemetry data

After yesterday flights, here some question about telemetry data explanation.

As you see on screenshot at some moment heli reached to 100% PWM (motor is reached to 100% of his power limit), RPMs dropped from 6000 to ~5000.

What does it mean (IMO):
- On some manoeuvres pilot provide incorrect collective work. Pushed collective management too much.
- Power system reached to power limitations.
- Here is not enough room for governor work.

On my eyes telemetry is not just beautiful graphics and fun, you can see where you need to improve your flight style and collective management.

Also you can see that on some manoeuvres power system is not enough powerfull.

Based on timestamp, you can analyse video when pilot push heli too hard.

For example on 1:01 heli was pushed on out of at the exit of the loop and overloaded power system

Is is right?

Hi,

imo right: you push 30+ A peaks throughout the log. At that times, the PWM maxes out, and the head speed drops.

If the governor opens up throttle to 100 %, and the head speed drops anyway, there's either not enough power (for the maneuver, stick inputs), or the gear ratio is not calculated with headroom (we don't have that here ...), or the battery's voltage drops significantly under load, or the requested head speed is too high for what it is.

Kind regards
