Why was 32kHz gyro sampling removed from Betaflight?

In order to access the 32kHz gyro sampling mode, the gyroscopes in question (e.g. ICM 20689) would be switched to an experimental mode where there is higher gyro data jitter, and that sampling at the ...

Can motors be "too big" for any reason?

Power systems should be balanced. If you fit motors that can handle more power than the battery can provide, you're just adding unnecessary weight. That weight will reduce performance in all areas. ...

How to program drones that have old flight controllers?

You can always run an older version of betaflight. Also, if you have older F3 controllers you may also like to like to look at https://github.com/spatzengr/betaflight/releases which are maintained by ...

Why can't quadcopters handle failure of one rotor?

I saw a TED talk from a guy who had written quadcopter software to handle losing one motor. Perhaps you can find it. With nothing to counter the unbalanced torque, the quad spun in yaw quite rapidly. ...

Why can't quadcopters handle failure of one rotor?

It depends on what you mean by "fly" Raff d'Andrea's team at EPFL wrote a stunningly good paper on this subject, with practical demonstrations indoors and outdoors. The paper, Relaxed hover ...

How to program drones that have old flight controllers?

Librepilot may be able to do what you want. I had it running an old CC3D board recently until I burned it into a parking lot at high speed. I prefer Betaflight so far, but I haven't really explored ...

How to program drones that have old flight controllers?

You'd need to provide more info on what "old FC" is, and same for ESCS. For the FCs - are they running an STM32 (F0, F1, F3, F4, F7) processor? If so the cleanflight/betaflight path is what ...

Why can't quadcopters handle failure of one rotor?

I've never written control software for tri/quadcopters, but I'd assume it largely has to do with the fact that a quadcopter minus-one-prop is fundamentally set up quite physically differently from a ...

Can motors be "too big" for any reason?

As far as I am aware, the main reason that giant motors aren't used on relatively small drones is power consumption. For example, look at an average 5'' drone using 2207 motors. In most cases, a 2207 ...

Would appreciate help! What is wrong with the ESC?

Most likely the FC is not arming the ESC for some reason. The best way to solve arming problems is to connect up the VTX and see what warning message BetaFlight is showing in the OSD. Also, in the ...
