Should I Enable Crash Recovery in Betaflight?
I'm setting up Betaflight for my first drone.
Should I turn on "set crash_recovery = ON" - it is not on by default.
I have a 2S 75mm tiny whoop with ducts.

What this setting does is return your craft to level after a crash is detected by the FC when youre flying in acro. Pros of turning it on are, of course, the craft self recovers after a crash meaning you are potentially more likely to be able to fly away from a wall bump/minor collision that would otherwise send you tumbling. The cons (and why a lot of people, myself included, don't use it) are that you are not in control of the quad anymore while its recovering. Now this is only for a tiny fraction of a second and it generally happens faster than a human could even react, but giving up control at all is definitely a no go for some pilots. There is additionally the risk of false positives and the crash recovery triggering when youre doing some extra-spicy freestyle, since the FC is just using the onboard gyro and accelerometer data to detect a crash, but from what I understand if you leave the parameters at the defaults this is pretty uncommon.
Bardwell has a pretty good video on crash recovery including how to turn it on and tweak it, as well as flight footage of it in action thats worth watching before you make a decision

But the tldr is its personal preference really if you want it on, a whoop is definitely the best application for it since the prop guards/ducts usually mean youre just bouncing off of whatever you crash into anyway (no risk of props getting tangled up like in open prop quads) so there's not really much risk in just trying it and seeing if you like it

DanielF737 - thank you very much for your time in answering my question, much appreciated. Bardwell the "famous know it all" sure lays it out. I've decided to just turn it on and try it. Seems like it is okay to use with low risk for a tiny whoop beginner. I'm a long way off doing 'some extra-spicy freestyle'. Cheers mate. Happy flying.

its great for whoops, but if you do a bit of freestyle, it feels much better if you adjust the settings a bit

@NullNullZero Thanks NullNullZero I will keep that in mind. I have no experience as yet. I will go with the factory settings and just turn it on and see how I go. I'm working through the tech voodoo first setup, making progress with it. Not far off flying.

I run these for crash recovery on my air65/75 and 2S meteor 85WS (Stolen from CiottiFPV), i fly full acro and allows me to do freestyle without interference from the crash recovery, but when i tank it usually saves it.
set crash_dthreshold = 80
set crash_gthreshold = 600
set crash_setpoint_threshold = 500
set crash_recovery_rate = 200
set crash_recovery = ON

Awesome - thank you for supplying the settings that you like and also for telling me of your experience using crash recovery with your 65/75/85 whoops. I feel a lot more confident that this is right for me. Cheers.

I just checked my existing factory settings and will make changes so that mine match yours. After watching Bardwell and looking at your settings and all the other comments it is all starting to make a bit more sense to me. Thanks again DIYFPV mob.

Just made changes in Betaflight, a few scary moments (all new to me) but I seemed to muddle my way through making the changes and can see that setting changes are now in place in the the CLI dump file. I need to watch a few more instructional videos on using Betaflight. Thanks again - another step forward - I feel good.👍
