I got a new 6S 1400mah Tattu R-Line V5.0 with new props, and I'm having huge problems. I remember hearing someone talk about that on a video on YouTube, but I cannot remember what it means.

I thought it could've been a loose prop, but it's already tightened enough. I've reset Betaflight's PIDs and rates to default in the video. I have yet to update my Betaflight.

Maybe I have a bad ESC, maybe I got a bad motor, I'm not sure. But the same motor that seems to have problems, motor 2, was really hot after only 1:30 of flight. I'm talking really hot, like I touch it for not even a second and I almost get burned.

I don't see many 6S quads with 1900KV motors, and I was thinking that maybe I'd need lower kilovolt motors for 6S? I got these motors so that I could run on 4 to 6S. I can run on 4S and 5S fine, but as soon as I put on this crazy Tattu battery, it's as if it was too powerful. I once flew with the same drone, but with different propellers with a Tattu R-Line V4.0, and it worked amazingly. I had higher pitched props back then (Dalprop Cyclone T5046C 5046) and different ESC configurations.

If it's a firmware issue, I'm thinking it's probably fixable with the Betaflight ESC configuration, but before I try and change any options, I'd like to know what this high pitch sound could mean.

Thanks in advance!

My drone's specs:

BTFL Configurator: 10.7.0
Firmware: BTFL 4.2.9
Battery: 6S 1400mah 22.2V 31.08W 150C
Motors: EMAX EcoII 2306 1900KV
[b][b]4 in 1 ESC: F40 40A 3-6S DSHOT600[/b]
Flight Controller: MAMBA F405 MK2[/b]
Propellers: HQProp 5X4.3X3 V2S 5043 5inch tri-blade

Not too clear, but high pitched squeals like a slipping prop are often the esc losing timing.

This can occur when a set up is marginal and an extra good (or higher C) pack is used. I have one high speed flying wing that I have to avoid high throttle for the first 30 seconds of a new pack, also occurs with older Blade Heli's that were never designed for HV packs. Again a few seconds use and the pack voltage drops enough to be OK.

Thank you, I think it might be a desync due to some ESC settings, I hope so. I still haven't checked into it though.
