New Filter Default Dynamic filter is now enabled by default, and Notch filters are disabled by default. New "stage 2" low-pass filters on both gyro and d term enabled instead of notch filters. The Betaflight development team has stated that the defaults should now work great for any gyro rate up to 32kHz, which was not previously the case. Since the filtering algorithms have been changed, we recommend you re-tune your quadcopter and try out the defaults. Using any TX with simulator via FC You can use your quad (or a spare FC) to play simulator with any transmitter. F7 Optimization F7 chips now run much faster, allowing 32k rates to be used. It's been confirmed you can enable Accelerometer, Barometer, 32K/32K, and looptime settles at around 35%. Amazing! Return to home feature If you setup GPS on the quad, it can fly back to your launch position if you lose RC or video signal. Other new features - Added acro trainer mode, it's a special acro mode that refuses to tilt past a certain angle. You can practice flying acro without risking flipping upside down and flying into the ground
- Overhauled and improved filtering with a specific focus on improving defaults
- Added support for accessing SD card / onboard flash as USB mass storage device
- Added support for flight controller configuration via the Taranis with Crossfire installed
- Added support for filter based RC input smoothing
- Added throttle boost mode
- Added support for throttle limiting
- Added support for accelerated yaw spin recovery
- Added “paralyze” mode to be able to remotely power down a quadcopter.
- RSSI improvements for configuring RSSI range in the flight controller (use the “rssi_scale” and “rssi_offset” CLI options)
- New FC Board Support
- SPRACINGF7DUAL with dual gyro support
- Iterm Relax reduces overshoot on sharp filps and rolls
- Throttle boost provides a feed-forward mechanism on rapid throttle moves.
- Filter-based RC Smoothing reduces input latency compared to Interpolation method used in previous versions

The BF Wiki should be consulted for any specific info on improvements, fixes, etc for each release. But yes, the new GPS rescue mode feature is pretty cool • Posts: 252 Threads: 42 Likes Received: 90 in 64 posts Likes Given: 184 Joined: Apr 2018 Reputation: 3 So dynamic filter only, or so I still kee gyro notch on in pid settings? Bardwell just did a video about keeping that on always I thought • Posts: 21,380 Threads: 593 Likes Received: 9,025 in 6,679 posts Likes Given: 1,428 Joined: Jun 2018 Reputation: 793 Most of you have probably already seen this but I thought it worth putting a link here seeing as it has some relation to the thread title.

It appears that the default filter settings may need to be tweaked a bit (for me anyways) That was something I didn't notice JB actually do in that video too. Was also curious how hot the throttle boost would make things, especially on a heavily propped quad. (which I tend to run fairly aggressive pitch with 2300kv motors) • Posts: 2,410 Threads: 136 Likes Received: 1,790 in 1,052 posts Likes Given: 3,302 Joined: Jan 2017 Reputation: 50 (17-Jul-2018, 07:28 PM)RENOV8R Wrote: Funny, I just updated 2 quads from 3.3 to stable 3.4.

I cam across this today as I was doing some homework  with your post in mind I had wondered if you saw it yet. https://github.com/betaflight/betaflight...flight-3.4 Just got in my new lipos to finally retire my old ultra saggy packs and might flash today. If the weather hold out for a while at least.

https://oscarliang.com/betaflight-tuning/ Great write-up as always Oscar! I have been debating whether or not to update before vacation. I think I will wait untill I get back though as my quads are flying pretty great to me already. What's your personal view of 3.4 vs 3.2/3.3? Does it noticable feel better or easier to get a great handling tune? Is it awesome enough I should flash before friday?  • Posts: 5,325 Threads: 675 Likes Received: 3,162 in 1,749 posts Likes Given: 2,034 Joined: Jan 2016 Reputation: 140 (24-Jul-2018, 05:26 PM)Drone0fPrey Wrote: Great write-up as always Oscar!

What's your personal view of 3.4 vs 3.2/3.3? Does it noticable feel better or easier to get a great handling tune? Is it awesome enough I should flash before friday? I haven't done a back to back comparison, so my opinion might be biased :  I feel like there is definitely an improvement in the default tune. 3.4 just flies so nice out of the box. There is also improvement on how the quad handles extreme maneuvers. It's not like day and night, and you don't have to upgrade if you are happy with what you have. But if you're building a new quad you definitely have to give it a try Posts: 1,773 Threads: 30 Likes Received: 1,199 in 755 posts Likes Given: 714 Joined: Oct 2016 Reputation: 45 • Posts: 1,314 Threads: 50 Likes Received: 833 in 505 posts Likes Given: 372 Joined: Jul 2018 Reputation: 51 25-Jul-2018, 04:48 PM (This post was last modified: 25-Jul-2018, 04:49 PM by Banelle.) 3.5 tuning notes Wrote:Goodbye D Setpoint Weight Dammit, Betaflight.
