Hello.

New to this forum and very new to quadcopters and very very new to FPV.

I mostly fly LOS as I live in a city and there are few open uninhabited spaces to FPV in.
And I mostly fly horizon mode as acro gets out of control.

I have a 180 and a 250 and they fly really different.

Anyway, both are naze32 with cleanflight using rewrite (PID Controller 1?)

Out-of-the-box stock (I got both ARTF) they are a bit fast and too reactive for me so I set up alternate RateProfiles and use a switch on my radio (Taranis) to change between the RateProfiles.

I am looking for some ideas where to start ... lower Rate and increase Rate Expo?  This seems to calm them down somewhat.

Suggestions on what to do with RollPitchYaw Rates?  Yaw seems to be okay for now.
Biggest issue is when I get a little aggressive they "get away" from me ... out of control, hard to recover, and mostly the result is a grounding.

I did read Oscar's excellent post “RC Rate” vs “Roll/Pitch/Yaw Rate” in Cleanflight Naze32 .... and it helped with some guidance.... one part confused me .... the part about setting RC Rate to 1 and only adjust pitch and roll rate.

Anyway, any suggestions where to start would be much appreciated.  


Cheers,

hi i am no expert but if you are finding them too snappy or reactive but are happy with the yaw i would lower the roll and pitch rate , try setting them to 0 and trying them ,they should be very docile, then increase them a bit and try again , repeat till happy . i would keep rc rate at 1 , use PID controller 1 and put rc expo to 60 or 70 .

In the past i flew in horizon mode and found the switch to acro a bit scary but now if i fpv in horizon mode i feel the quad is fighting me all the time trying to self level and i would never go back , acro LOS is a bit more tricky to learn you just need to get the muscle memory into your thumbs from lots of stick time , try just hovering over one spot 3 feet of the ground pointing away from you once your good at that turn it 45 degrees and repeat , when you can do that turn it 45 degrees (side on to you ) and repeat then turn 45 degrees and repeat , the hardest will be when if faces you as all controls seem backwards . keep practicing and day by day you will get better and at some point you will not think about the stick inputs you are making they will just be second nature to you . good luck

So the historic reason for having RC rate and those rates for pitch/roll/yaw was .... pitch/roll/yaw rates would affect PID loop.... so people used to adjust these rates separately...

however this is no longer the case, RC rate has simply become the multiplier of the other 3 rates... so you can now safely ignore RC rate and just tune Pitch/roll/yaw rates

I hope that answers your question?

Thank you for the comments, very very appreciated.

I understand now.  RC rate is on-top of the pitch/roll/yaw rate ... no sense in adjusting RC rate when you can just adjust the individual pitch/roll/yaw rates.

I'll try dropping the pitch/roll rate and then use switches/sticks to increase them until a good number is found.

And thanks for the LOS/Acro comments jack ... acro is quite different .... seems to be easier to fly with FPV versus LOS.
