There will always be people scrutinizing saying someone posted a video and made mistakes, but clearly the video wasn't geared towards who makes what and whether DJI was the first... the video is about tuning the snail system, which up until now, I was about to toss in the garbage (not literally, the motors are absolutely awesome). I changed my pids to these super low settings, and it was perfect. Thanks so very much, you earned a sub!

I have nothing but problems with this propulsion system, myself and others have nothing but issues with it, "wobbles of death" is what we call them. your video may have shed some serious light / insight for me! I build several quads a month typically, and this one escaped me as far as tuning and issues. I am used to my fair share of problems, but this is the first time I have seen something as severe as this (the wobble). It's crazy, the quad will hover, but after a flip (LOS) it will shake violently, wobbling left to right, all while ascending and at ZERO THROTTLE! I reduced PIDS to try and compensate, but apparently not low enough. I thank you severely, as you make have prevented me from tossing this system out the door!
I knew the PID loop needed to be 1khz, but the need for such low PIDS escapes me, I typically run pretty high setups when they are all tuned and locked in.

Thanks so much for posting this. I just built my first mini-quad. Used the RMRC Valorem VRF 230mm frame, Tattu 1300Mah 75C, RUncam Mini, BetaFlightF3, Diatone SP2 VTX, AUW is 496grams. It flew amazing but yeah if I did a hard roll it would wobble bad and even at low throttle amp draw would spike at 65A. I didn't know about the extra low PID values for this kit. Will be going out this weekend for a tuning session. Will start with your video values and going from there. I did update the firmware on the ESC's before I soldered the signal and ground wire to the FC. I wonder if the newer firmware is a little more tolerant of the stock PID values as that's basically how I flew 7 packs through it on Friday then a casual fun race on Saturday.

Thanks again and cheers!

I had my maiden with a diatone GT2 with snail propulsion - i was pretty impressed apart from the thing having a bit high lowest idle motor speed. My quad is a bit porky running a Session and 1500mah 4s @ 600g so it does not exactly defy gravity. This video helped so thanks for that, i usually start the pids pretty low when tuning but not as low as this.

Aerial GP - thanks for the video. Love to hear what, if anything, has changed for you on this setup since you originally did the video? I just got the build setup and it's similar to yours (Shrike frame, Betaflight FC, snail system) and curious if software updates for DJI changed anything. Thanks in advance!

Yes there are motors from Prop companies... DALPRop and Foxeer are part of the same main company and Foxeer are releasing some ESCs and Motors. ;)

hey man, i have to start out by saying this video looks amazing. but is there anyway to translate these numbers into kiss fc numbers?

[Gari]

Would you please review the Dji goggles racing edition

[lukedarb]

with the snail esc do you have to use the dji esc programmer to configure the esc before you install to your quad?

[HarleyFPV]

Well Gemfan has Maverick esc's and Motors ...ohhh and props ;op How is SNAIL easy'er when u still are tuning with same betaflight as other esc company's ?

What are the value of d setpoint weight and transition
