NURK’s Betaflight Settings Overview (3.5.1)

Introduction

As part of a little series on betaflight 3.5.1, I’m building out an overview of the settings that I’m using and why

Full Dump

Step By Step through Settings

  • Rate Settings
    • These are my race rates! 1.03/.66 RC/Super on all axis.
    • Fun Fact: this is “ratebank 2” on the DRL Racer3s
    • 606 DPS
  • PID settings
    • in generaly P and D have been turned up, with a couple ticks of I increased from default. I found that default PIDs flew great, but I wanted it just a little bit tighter. I noticed especially on the roll axis that it was a little loose, so I tuned up the overall PIDs just a little bit \
    • For the Yaw axis, I borrowed a suggestion from Bardwell that suggested a low P, high I, and zero D, with a higher FF setting than default. I haven’t played around with this too much, but it does feel very solid and I’m very happy with it.
  • Feed Forward Settings
    • This is where the magic of BF 3.5.1 starts for me. I run 150 on pitch and roll, and I run a low-P yaw variant, explained above
    • At default (60), I found that the feel of the quad was much less stiff than I wanted it to be. Initially I turned it up only 20, but I started to notice big gains when I got into the 100 range for the FF settings on P/R. Up at 150, the drone feels insanely locked in, with what seems like zero negative impact from any bounceback or such nonsense, as is the worry when you increase the F vaule too far.
    • If you’re interested in learning more about why I’ve increased these settings so high, please view my blog explaining in further detail

  • Feedforward Transition
    • NONE! This essentially makes it so that the feed forward settings we’re adding don’t impact the drone until they’re X% of the way through the stick movement, which, basically undoes the movement that you’re asking it to do.. which is silly.
  • Throttle Boost
    • I haven’t played with this too much, but it definitely seems to make the quad have more top-end than it used to, so I would encourage you to play with it.
  • ¬†Absolute Control
    • Haven’t really found an explanation for this, and I have left it default
  • I Term Rotation
    • Left Default
  • Smart Feedforawrd
    • Leave default — for FPV Racing, this setting should be left off. It’s likely to not even be left in Betaflight.
  • I Term Relax
    • Basically helps support Feed Forward “ignore” the i term, and send your stick commands¬† through to the sticks. Leave on RP for sure, consider having on Y if you fly yaw heavy (I do not).

    Sweet settings, bro! Just tried ’em out and it feels great on my Floss. Had to tighten up P just slightly. Thx for sharing! Keep up the great stuff!
