Hey everyone, Another newbie question - LOL I flashed my FC today to BF 4.1.1 (previously was running 3.5.0). After the flash it seemed like my FC was completely erased so I had to start over, no big deal. I got everything all set including adding my telemetry back. It seems like the default PID settings in BF 4 are perhaps more aggressive? When I arm my quad now, it seems like the blades spin up so fast that my quad just flips over and disarms. I double checked that my motors are all spinning correctly, and that my props are installed correctly. Any suggestions on what I should look at to troubleshoot this? I'm wondering if there is just a BF setting I've overlooked somewhere. Thank you as always! • Posts: 12,099 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 Things to check.

I just tried that, but even after the "save" command and the quad disconnecting and reconnecting, it keeps defaulting back to 2700.. so, I instead went to the Configuration page, under the Board and Sensor Alignment section and changed the "First GYRO" drop-down from "CW 270" to "CW 180" and saved it.. I'm running the latest BF Configurator 10.6.0 so not sure why it wouldn't save through the CLI. I'll try out the quad first thing tomorrow morning to see if it worked.. • Posts: 21,302 Threads: 589 Likes Received: 8,987 in 6,652 posts Likes Given: 1,426 Joined: Jun 2018 Reputation: 789 (19-Nov-2019, 02:49 AM)eforden Wrote: I just tried that, but even after the "save" command and the quad disconnecting and reconnecting, it keeps defaulting back to 2700.. so, I instead went to the Configuration page, under the Board and Sensor Alignment section and changed the "First GYRO" drop-down from "CW 270" to "CW 180" and saved it..

That's weird that it wouldn't save in the CLI on yours because it works fine on mine. Yes, the result you are looking for is First GYRO set to CW 180 so what you've done in the GUI instead is correct. It will fix your problem. Don't ask me how I know Posts: 12,099 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 Can you post your dump file? • Posts: 116 Threads: 6 Likes Received: 29 in 20 posts Likes Given: 3 Joined: Jul 2019 Reputation: 2 (19-Nov-2019, 02:43 AM)eforden Wrote: All of those look good, BF is correctly responding correctly to the stick movements on my transmitter. on the set page, first tab, that shows "calibrate accelerometer". There is a graphical representation of your quad. rotate your actual quad clockwise? does the graphic match the movement? pitch it forward? does it match? roll your quad left. does it match? if one of these actions does not follow suit, then one of your axis is off and needs to be adjusted. i.e. ROLL degree, YAW degree, PITCH degree located within the Configuration tab page. • Posts: 53 Threads: 9 Likes Received: 3 in 2 posts Likes Given: 10 Joined: Jul 2019 Reputation: 0 (19-Nov-2019, 02:58 AM)SnowLeopardFPV Wrote: That's weird that it wouldn't save in the CLI on yours because it works fine on mine.

Don't ask me how I know Yep, you were correct, that fixed the problem!! I'm definitely curious about how you figured that out... • Posts: 21,302 Threads: 589 Likes Received: 8,987 in 6,652 posts Likes Given: 1,426 Joined: Jun 2018 Reputation: 789 (19-Nov-2019, 01:58 PM)eforden Wrote: Yep, you were correct, that fixed the problem!! I'm definitely curious about how you figured that out... It was an intelligent calculated guess based on a bit of knowledge and my own experience. I've got a Matek F405-STD flight controller which runs the MATEKF405 target and when I updated that from Betaflight 3.5.7 to 4.0 it required me to manually reconfigure the gyro orientation from the default of "270 CW" to "180 CW" as detailed on Matek's main product page for that FC ( HERE). The flight controller for the Tyro99 and the Tyro109 both use the same MATEKF405 Betaflight target...so... 2 + 2 = 4 I'm glad you are now back flying again Posts: 53 Threads: 9 Likes Received: 3 in 2 posts Likes Given: 10 Joined: Jul 2019 Reputation: 0 19-Nov-2019, 07:26 PM (This post was last modified: 19-Nov-2019, 07:27 PM by eforden.)

Very nice, you were spot on with the MATEKF405. I just took a look at that link and see the highlighted banner about updating that after flashing to BF 4.x. Thanks so much again for your help, I just realized too that I completely forgot about specifying that my quad is the Tyro 109! You obviously have a great memory to remember me from the other issues you've helped me with so far Onto my next project - adding GPS to my Tyro 109! Should be here later this week... • |
