10:40 I guess you can also use a 3 position switch to set 3 different uptilts. One at 40° for flying fast, one at 30° or 20° for freestyle, and one at 10° or 0° for exploring and landing. That's why I'm watching this video, to try to learn to set this up.

again, thank you, your tips are life-saving !!! so hard to debug without these tips.

[realright]

Thank you so much Bardwell! No where else on the internet does it say that you need to have the aux channels turned off in the Servos tab, you help save me a lot of time :)

That dance at the end was MASSIVELY deserved! The series was unbelievably helpful as I've started digging into different settings in Betaflight!

[PurpleLich]

Can't believe I made it through this whole series. My head is too full of knowledge! 🦁 Thanks so much, JB!

It's crazy how there is almost zero information online on this topic! However, your video has explained everything I needed to know and more!!! Thank you! this was so informative 💯🤞🏾

The 1/2 output numbers on the airplane at the front of the model are for the motor outputs. Planes can have motors :). On INAV there is no need for the DMA to drive the servos, so I think it is the same on Betaflight. You can remap the motor output pin to the servo, as long as it does not share the timer with the other motor. Also, the possible resources for the servos are UART6 RX & TX (on F405 and F7xx), but it depends on timer assignment and motor allocations on PC8 & PC9 pins, if there are motors assigned there, it might be impossible to run servos on UART6 due to the timer conflict. The LED strip is a save resource for the extra motor or the servo, but then you loose LED function. Timer allocations can be checked and changed in the CLI.

Thanks JB! I'm eventually going to put a drop mechanism on my 7" drone. This video should at least point me in the right direction.

The syntax to change channel forwarding start is a bit different than the way resources were assigned. To use AUX 4 as the first forwarded channel, use:
*set channel_forwarding_start = 7*

It took a while to figure out the correct syntax since Bardwell didn't change this setting in the video.

Remember to type:
*save*

After you make the changes. I forgot to do this myself the first time I changed the resource values. I haven't had to make changes via the CLI prior to forwarding channels for servos (gimbal control).

Thanks for all the great content JB.

17:00 I am that person and now I can finally see light at the end of the tunnel... thanks

Great video! Just added a couple of servos and this made it easy! Btw, I tried iNav too. Added a GPS for return to home. Frankly, it wasn't worth it. I probably could make RTH work better, but it is so far from DJI it's just not worth waiting for GPS lock. And, I personally don't think iNav flys a quad as well as BetaFlight. So, I dropped the GPS and went back to BetaFlight and am much happier.

seems like theres more than one person who needed that info, on this vid. great job at explaining.

[BigAlFPV]

Thank you Joshua for your hard work in making this series of Betaflight 4.3 I downloaded the official release of it the other day & will use your videos for reference

[TheReaperGrim]

Thank you Sir, just got fpv combat bored setup through this 👊✌🤟

[gmivisualsjason]

Thanks JB. I've learnt something today

[FastyFPV]

thanks for the whole series. learned a lot from it.

I remember that channel forwarding thing all too well because of the Matek PDB that I used back then for a long time.
It had a buzzer onboard that was only usable through an AUX channel being forwarded to a Servo channel.
I remember being so proud of myself once I figured it out, hehe.^^

[turionb]

You are awesome. Watched the whole playlist. Thanks man!!

[leonardothillet]

This content is so fascinating and addictive I watched this whole video even though I am probably not going to use servos ever. lol

[maddercat]

Got mine working, first servo on betaflight, too cool. lol Very simple camera pitch rig. I should put this on all my quads. lol If I had a job I'd sub to your patreon. LOL
