your vtx antenna mission is pretty funny

I started building Quads in August 2022... after my intro to drones via DJI (Mini 2, Air2S & DJI FPV). Since then, I've built 5 quads. Crashed & Totalled the first one in less than 30 seconds. Rebuilt it on a different frame. Crashed and drowned it several times after, put it back together again and it flies so well I don't know what else to do with it. Every other quad has been nothing but trouble to tune properly. Bardwell's videos helped quite a bit... and then he mentioned you in one of his tuning videos. If he was excited receiving info from you, then you were worth checking out... and I did.
Mr. Rosser, your content was made specifically for my needs as a quadcopter enthusiast. I was initially reluctant to watch this series of BF Tuning videos (because of time). But after getting started, I realize I did myself a disservice waiting so long. I should have started sooner. You have given so much to the FPV community (& Mr. Bardwell). Many thanks... many times over. I plan to continue building and flying quads and have plans to get even more involved than I already am. So, I'll be seeing you on your discord server soon.
Thanks for all you do. Thanks for making all this technical stuff easy to follow. Your work and expertise is appreciated.

I find myself coming back to these videos so often

[andrewkhoolightstalker]

Thank you, Chris 👏🏻👏🏻👏🏻 This BF4.3 series is gonna be in my "study", DIY & watch later playlist!

[Carboneye]

Thank you so much Chris! just set my filters up as you suggested on my Aos 5, & 5.5v2 and they both now fly even better. Amazing bit of knowledge here guys try this!

[sakfpv]

We're going deep on this one, so strap on. Thats what i heard

[christianmmoser]

Thx alot Chris for this great video. I also watched all your videos in the tuning guide for BF 4.2 and I would highly appreciate if you could do a video where you just point out the differences in tuning in comparison to your "old" BF 4.2 viedeos.

[princesfpvdrones]

Explained really well, thanks Chris, you are a great value to this community!

[BrandonBeans]

Great content here, Chris! The filter overlays were really clear to visualize the expected filter response from either tune and I love the dynamic lowpass tuning strategy tips... Well done!

Love these techy dives on the deep side of the pool thank you. After switching to 4.3 I had no idea of what I'm doing. After watching your videos I have to admit, I still don't know what I'm doing, If I sound like the FNG. Yes I'm an FNG. LOL, but am glad there are pictures. Anyways all silliness aside, thank you for these videos without them I would not be flying today or tomorrow or the next day, Had copied and pasted some of the presets and didn't like them, everything seemed mushy, like flying through mud. After seeing your tuning 101 video's for 4.3, I saw that Dymanic damping was turned down & no Gyro filters, made my day. Gees Thank you.

Excellent content again! You should really put a disclaimer in the beginning to tell people that this is for 5-6" quads. Anything substantially out of that range requires not only different numbers but most of the time totally different filter-strategies.
Keep ripping,
Volker

Great videos! So much to learn and remember, I wish I had a cheat sheet of your videos for the drone room wall, like a slide pack with the key points to jog my memory 🤔🤔

[kvngnz]

eagerly waited for this part of the video! thank you!

[jtr]

Oufff. You make tunning so easier!!!! ThaNk you

[stevejakab]

Another great video Chris. Would really appreciate a tuning video for the AOS 5.5 as well

[GTRFPV]

You are my hero! Good stuff. Thank you.

[caymandiver]

Awesome series of videos for Betaflight!

[thfpv]

Bern waiting for part three thanks chirs!!!

[chrisyoung]

I wish that BF configurator showed you the phase delay for a given filter setup.

[ColinZenger]

To be honest I wasn't very successful with tuning 4.2 so I am now trying again with 4.3.
After watching both "seasons" from you, I feel quite prepared.

Any tips on the first flights for getting logs to set up filters? Some full throttle punchouts needed, or some spins?

Thanks a lot for all you helpful information!
