Yes, you will need the corresponding tool version.
I incorrectly said firmware 1.28 - I meant tool 1.28 and firmware 3.65 (corrected the above post).
The archive page here does not have 1.28, I’ll find you a link.
It’s a flipsky problem.

Thanks @agentdev.
Managed to revert to a previous version of VESC Tool in order to be able to try 3.66 (FS responded that they use and have tested 3.56 and 3.66) .
I’m afraid the behaviour is the same. Please take a look at the video which shows basically the same as the first one:
Looking more like a problem in the FSESC…

Have you performed hall sensor detection for the corresponding ESC? Any bad temperature readings with realtime streaming?
Ah yes, thanks for the reminder 
My motors are uncensored, guess that is not possible to do?
I would be tempted to try the new HFI FOC mode… it requires the latest tool and firmware. This supposedly detects motor position fairly well without having hall sensors, but I have yet to give it a shot.

I tried it because my startup from standstill completely sucks. Didn’t work though. I followed the tutorial in order to adjust the parameters but my plot was always a mess and the end result was infinite cogging.
So far my experience with an under $100 Chinese ESC from my previous build has been much better and totally flawless.
Did you run motor detection with the belts removed? The FSESC works great in FOC mode, but that is usually with hall sensors.

I liked the idea and, to be honest, had some hope this might fix the problem but I could reproduce it again without the belts 
There are too many good VESC manufacturers to be paying out the ass for Flipsky shit that may or may not work out of the box, and may or may not throw you off the board for no given reason.

Speaking about that, I only know Trampa HW as an alternative but it’s bloody expensive. Could you share some good alternatives? Up until now have been delighted with my cheap chinese 50A ESC

The ZESC that started on this forum is incredibly robust, however also around 50a constant, currently out of stock. Makerx has their 4.12s and V6 VESCs for about half of what flipsky sells them for. Shaman is working on a diy V6 for >$40 and Jeff Wu is bringing back an upgrades v4 focbox and a V6 focbox (both called neoboxes). Maytech 6.8FOC are an option under $100USD aswell per esc. If you cant find something you like out of those, then I don’t know what to say.

It seems that out of those that are not a work in progress, the Maytech is the only one that could handle at least 100A. However, the price is similar to the dual FSVESC as each single one from Maytech costs over a hundred dollars…

None of them can handle 100 battery amps per side, and you don’t need 100 battery amps, meepo hub drives use 10a per motor and can still get up to 32mph, unless you weigh 150kg, 30-50A per side is enough to get you moving quickly as the max current is really only used on acceleration or up a large incline. I wouldn’t trust the flipsky enough to go quickly but I would trust any of the other ESCs more than flipsky. The makerx dual 4.12 is $120usd, it comes with a heatsink and the solder joints aren’t all cold.

I designed my MTB build for 50A on each side, so 100A in total.I think that that is a reasonable requirement and for less than that I would have stick to my chinese ESC that always worked so well…
From your list, this is what I could gather, correct me if there’s something wrong:
ZESC - out of stock
Makerx 6.6 - Continuous 30A (60A dual setup)
Shaman - work in progress
Jeff Wu - work in progress
Maytech 6.8 FOC - Continuous 50A; $115.99
The Maytech could be an option from me, but also a bit expensive. With a case and anti-spark switch it costs 2 x $165!
Not sure if you resolved this, but I had a similar issue with my FSESC 6.6 dual from Flipsky. But really the issue was a bad connection in one of my phase wires (bullet connector came unsoldered). If you can reproduce the behavior on the bench by jiggling the phase wires, then there you go.

I had similar issue with a chinese ESC in the past.
It turns out the canbus cable/connector was bad. jiggling that on the bench re-produced the issue

Thanks all for the tips. I’ll review the cables and everything I can think off next week and I’ll let you guys know…

Respectfully disagree. I am pushing 76A per side on my flipsky dual vesc 6.6 on firmware 3.65 without any problems. I have 3 different boards all running 3.65 and I have never had a single issue. I would never be satisfied with a hub driven motor at 10a, or any hub driven setup, ever. Gear drives or belt drives are the best way to get gobs of torque. That’s like comparing a Honda Civic to a brand new Lamborghini.
