Great video. It is worth pointing out that 5" quads can get away with a low Startup Power like you showed, but micro drones often need a higher startup power. In particular, a lot of whoops and toothpicks will fail to start properly if the Startup Power is that low. I'm talking about 06xx to 08xx motors in particular. One or two motors will sometimes twitch instead of starting properly. But if they do start, then they work just fine until they stop again. In that case, increasing the Startup Power usually fixes it. In fact, some manufacturers ship their whoops with Startup Power max out at 1.5 for this reason. Just something to consider. But yes, on 5" drones it does not need to be that high. A high Startup Power on a 5" drone will cause big current spikes. Not only can that cause the ESC to reset (make the startup tones if you're close enough to hear it), but a high startup power on a 5" drone can also increase electrical noise showing up in the FC and FPV. That's my experience anyway. Keep up the great work!

Do you maybe have a suggestion what to set the minimum startup power to with Bluejay firmware? there are different units there (default is like 1025 to 1100)? I just had a motor desync when testing pid tune with rapidly reversing stick motion and I'm not sure how to prevent it in future.

[@Daclaem]

I have this on and ELRS setup , unfortunatly none of the tips you gave fixed the issue of random savage desyncs espêcially with 6s batteries. I m out of clues .

[@michey7822]

awesome! just had a desync this weekend, so im gonna try this

[@Krash_fpv]

I am so close to selling my quads....I put bluejay on all of them but both my 5 inch quads are literally deathrolling every time I try to roll them....nothing is working and I am not throwing more money at them

[@gus8378]

Cool frame. What is it?

[@pukkafpv]

Great video I'm running 4s motors on 6s by scaling them down in betaflight will this work and will I still be able to use both 4s and 6s with the start up power lower

[@DronemanfromNepal]

I had twice in Blheli 32 esc !

[@KCQuadTronX]

thanks thhis really helped

[@leo1477]

but how to do it on bluejay?

[@subbunny]

Dr. Quad. Everything i know about tuning, i’ve learned from you! Thanks for all the very informative videos! knowing how everything works on a detailed level really helps it stick (or gimbal?).

[@maadfisher]

Short and informative, my favourite kind of video! Thanks and stay safe.

[@meralharbes]

Awesome summary! I had collected a big note file with tips to combat desyncs over the last year or so, this video made a lot of that redundant and would have helped me so much had I found it originally! Thanks!

[@corpsefpv3154]

Thanks for the tip! The start of the video looks exactly like what I've been plagued with so I'll try these!

[@dasppg9737]

Thank you so much. Your video solved my problem with a build. Installed some 1507 flat rat 2800 kv motors on my taycan mxc 3” (6s). I thought there was an incompatibility between the flat rat motors and the newbeedrone cricket 200 stack. Had some poor flight characteristics during flight and noticed desync during abrupt full throttle blips. Adjusted the settings as your video suggests and the throttle blips no longer cause problems. I’ll test fly tomorrow to see if the other flight issues have been solved. Thanks again!

[@johnnormanrivera1671]

a couple days ago i had the same problem, non of these method works but after updating the FC firmware and shorten the motor the problem SOLVED!!!

[@B3NSipodtouch]

Was having these issues with another quad last week thanks for the helpful info

[@TRITONFPV]

Thank God that hasn't happened to me in years. Saved just in case I ever run into that issue again. Thanks for the vid 🤙🏻

[@RogerBaroudy]

great video, you nailed all the desynch causes, for me dynamic idle caused desynch problems on 2 quads even though the instructions from BF wiki were applied to the letter.

[@MCsCreations]

Great tips, Mark! 😊
