Default Is this Wookong TBE?

Here is my unedited video, at about 10 seconds it seems to have slight toilet bowl effect, but I am not sure.

This is unedited with gimbal stabilization off. Just a go pro mounted to my gimbal, flying around my 700e.

This was just a quick flight out of my truck in a new location, no gps calibration, or prior testing. First time I've ever had the white lights blink in gps or atti mode, meaning poor atti status. Probably should have re-calibrated. Take-off elevation is around 9000ft

You need to work on your throttle curves!

There does seem to be a TBE

There are variarions in headspeed when you ascend or descend, also also when you yaw, it does not sound right.

I don't know what heli that is but head speed sounds kinda slow, maybe the cause of your wobble!

It's a pretty much stock 700e. It was gusting some that day and really cold, some of that is probably due to my thumbs. I think the HS is around 1800. What do you suggest to tame that down a bit?

I fixed one issue at least. The Wookong needs to be setup In Rate mode before HH mode. It was setup with zero pitch that day and having all kinds of spastic tail response. I've got about 6-8 degrees of pitch in the tail at center stick now (In rate mode) and it doesn't have that springy acting tail. Much smoother now. Also, my swash was completely not leveled right.

I might be wrong, but it definetely sounds like 1400-1500 to me, at least mid-air, at spool-up maybe 1600-1700.. HS drop may occur in underpowered setups, maybe old LiPos, maybe frozen LiPos. Just my observation.

I was going to PM this to you craneman but I'll throw it out there for everyone. Turns out that I was running my 6s packs in parallel instead of series connection. So I had 10000 mah 6s not 5000mah 12 s. So does this kill HS? Can't believe you guys could hear the problem, all through a crappy go pro.

This definetely is the cause, it means the HS was even lower than expected before. The HS formula would look like RPM=(Voltage*Kv/Gear ratio)*Throttle%

Great. It was definitely flying poorly. It had no power and much less stability than before. In wind, a few mph was noticeable, where 15-20mph wind was fine before. Also won't this give the tail a little more control as well?
