Hi Guys, here is Davide, welcome to my YouTube channel Today I’m going to show you some tips and my PIDs about Betaflight 4.0 Please subscribe to my channel and don’t forget to click on the bell to receive my notifications I’m going to show you some basic tips on Betaflight 4.0 I am not going in depth, guys, this is not a video for nuclear scientists If you want more details, just check the link on Betaflight 4.0 on the description below I’m skipping the installation steps because on youtube or on the web you can find tons of BF 4 guides and tutorials I want to focus more on the flying I waited some weeks to share this video because I wanted to test more BF 4.0 It’s very different from the previous versions Let’s start with my 1st tip Betaflight 4.0 is not a miracle worker so do not expect that after flashing this firmware you’re going to fly like the best pilot out there my next tip is: focus more on your rates, because rates are more important than pids find your rates and then focus on your pids Damned insects inside my car!!! The first time I tested BF 4 I was not so impressed so, if you have a super tuned quad with the previous BF versions you’ll be disappointed but when you understand how the new firmware works, results will be amazing! Developers improved a lot the way filters work and they changed the “P” and “D” interaction on the quads if you don’t know what are “P” and “D”, please watch my “PID Tuning” video linked in the description below My first feeling is that “P” and “D” work less compared to the previous BF versions The value you should increase is the “I” In BF 4 you should boos it One of the best feature in BF 4.0 is the D-MIN, I love it so much Now we can fly with a low D value and BF boost it during aggressive tricks like fast rolls and flips Another good feature is the “TPA only on D” What is TPA? TPA is a value we can use to decrease our “P/D” % on high throttle curves In BF 3.5 and in the previous versions, TPA works only on the “P/D” (at the same time) Finally with BF 4 we can tune the “TPA only on D” value Developers, after testing it, noticed that the TPA P/D interaction was not so good on high throttle so they decided to introduce the option to tune only the “D” parameter at least but not least…the famous RPM FILTER but what is this RPM FILTER guys? RPM FILTER is a feature introduced with a specific version of BL HELI 32 firmware you should flash on your ESC I’m not going to explain how to configure it because there are tons of guides on YouTube Thanks to this feature, your Flight Controller, using your ESC, will be able to filter better the motor noises and vibrations so it can isolate better only the good frequencies and stabilize better your quad I tested it both on new and devasted builds and I can assure you can’t see many differences on new builds but on devastated builds, like the one I’m going to use today, results are such amazing! so…where should we start? First of all, after flashing BF 4, set it from scratch DO NOT PASTE OLD DUMPS INTO THE CLI! Because BF 4 is completely different and you may risk to break something Next, go to the BF 4.0 tuning notes web page, linked in the description below there you’ll find 2 configurations: 1 for freestylers and the other for racers Here we are freestylers so I focussed on the first configuration Copy and paste the values in your CLI, type SAVE and hit ENTER This is your starting point for your tuning Now I’m going to show you 2 flights: 1 with the default configuration an the other with my tuned settings I’m going to show you my model setup too and now I’m going to fly because I’m tired of talking This is my TBS SOURCE ONE, BANDO approved guys this is a devasted build, with destroyed motors (RR HypeTrain 2306 2450kv), look at the battle scars here You’ll hear the shitty motors sound, it sucks I use an HOLYBRO KAKUTE F4 FC with a HOLYBRO TEKKO 32 35A 4in1 ESC TBS NANO RX TBS UNIFY 5V VTX Menace stubby video antenna, destroyed, but it works soooo good, only the TOP contused Immortal T, as you can see the unmissable Foxeer Predator V3 FPV cam I’m shooting with a GoPro Session 5, my last survivor Worn and scratched props: T-Motor T5143, my favorite props Ok, I’m ready guys I’m going to set the default settings, here it is perfect save and reboot sun is out Let’s arm You can hear the shitty motors sound we are testing default PIDs DAMN loot at this sun! so…let’s test the air attitude some oscillations when going down with the throttle see This is an old battery now let’s test the turns My feeling: it’s a bit sloppy…yes a bit… Guys I can clearly feel a low I value a bit of propwash ok let’s go for a slalom see…they improved fast turns so much mmm a bit sloppy here some oscillations mmm not so much but yes, I can feel a low I value see…some oscillations when I go up and down with the throttle…only a bit Let’s check it Guys…it’s a good firmware but default settings are worst compared to a tuned quad quad is not so solid in the air you can feel it on fast moves and it’s not so evident on soft moves if I go for fast tricks I can feel it, it’s not so solid look…here some oscillations remember today it’s windy ok let’s test my propwash see guys, they have improved propwash so much generally, this move triggers easily the propwash Instead…see it… I’m trying to trigger propwash BF 4 can handle it a lot better Amazing Remember, I’m flying a devasted BANDO build Motors suck With BF previous versions I trashed them for sure Now I’m going to land, change my BF tuned profile and let’s see the difference Let’s land and change profile I change my profile and I switch battery this is my profile, my PID…you’ll find the BF screenshot after the flights I’ll change my LIPO and I’ll be back I’m back…look at this golden hour! Profile is ok, check my PIDs guys Let’s see the difference I increased the I, as you can see…you should boost it when using BF 4.0 so… I’m ready save and reboot Let’s test it Wow…I can just feel it, as I increased my throttle Look Amazing check it damn it flies like a dream so… let’s check it let’s go for fast turns as before what… what a difference now as you can clearly see guys I hope you can see it perfect so perfect see how it’s more solid during fast moves see…I’m trying to do the same moves as before perfect ok…now… let’s test propwash see this move trigger propwash like hell see it…unbelievable ah…let’s enjoy this lovely golden hour so good remember…motors are devasted what…see how it stops O_O’ damn… …and this is BF 4.0 guys need I say more? Freestyler’s hair!!!
