Hello everyone ! 🙂

Sitting on the prob now for >2h, reading FAQs, Manuals, etc... no solution so far:

When updating a perfectly fine working drone from BF 4.3.3 to 4.5 the motors won´t spin anymore. Everything ales works fine after editing config and so on (VTX, Radio, OSD, GPS). I can arm the drone via Radio... but throttle doesnt do anything, even the 5% motorspinning wont start....

So, I did a clean flash again, no change of any parameters in BF Flash options.
Going to Motors-Tab: no spinning in MOTOR-TEST-Mode !
Same thing in 4.4.3 clean flash: motors spin like they should.
Settings like before: DSHOT300, QUAD X... nothing wrong, nothing different than wir 4.4.3

So its definetly a software/settings thing... ?!
I already compared the DMA and TIMER values (since I found infos about this as a possible problem...) but they are the same in 4.4.3. and 4.5 when I check them.
Flashing back and forth... never got the motors spinning with 4.5.

I found this page here: https://github.com/betaflight/betaflight/issues/13148

But to be honest: I dont understand it completly.. does it mean, that this FC and ESC wont work with 4.5?

Thanks a lot in advance for any suggestions!

UPDATE: with clean 4.5. even in BLheli or with https://esc-configurator.com/ connection.... motor test wont do any movement... strange. With BF 4.4.3 its all reacting as it should...

so it is an ESC software issue?!

What is the ESC running now - BLHeli_S? Flash it with Bluejay and run bi-directional DSHOT.

#

Not home to check right now, but I believe mine run DSHOT600. Bluejay motor timing 15 and 24kHz PWM. You can also run it 48, less authority but longer flight times.

#

I have the same quad running on 4.5.

Okay... that was one of my next steps anyway.. right now its BLHeli_S...

just flash Bluejay on 4.5 or donwgrade , than bluejay and upgrade BF again? does it matter? can I flash back to BLHeli if necessary ?
(never did ESC updates so far, worried to damage, since its working fine on 4.4.3) 😉

UODATE:
yesterdays i gave it one more try with the RC4 of 4.5... flash, no settings changed... and the motors worked in motors tab! cool. so, props on, start: NOPE!! massive flip, props destroyed... i justed checkd it in BF configurator: the right motors (1&2) spin normal (like shown in pic), the left one are opposite direction. VERY strange behaviour... and i dodnt touch the ESC yet... mhmhhm.

I´ll keep u all posted.. but seems to be a bug with 4.5 .. i already found a post here with this topic. should be better in 4.5.1 🙂
