Align TREX 760X in F3C Fuselage Second Flight/Hover Testing

Just got the Align TREX 760X installed into the F3C fuselage. This is the second hover flight.
Still working through a few issues with the un-commanded collective, but it’s intermittent and only happen a few times during this video, starting right around the six minute mark. It’s very subtle, but it’s there.
During yesterday's first hover flight it was very noticeable and I was trying to see if I could capture what's happening in the video for troubleshooting and documentation, but today was not the day, but figured I would upload anyways to have a record. Frustrating when the issue is intermittent, but I will get it figured out in time!
Since the first video posted, when it was is pod and boom configuration, I have switched over to a dedicated 2S battery and Xguard Intelliswitch, installed another BD Axon FBL unit and the issue is still present. Scorpion Power Systems has gone through my telemetry logs and are not seeing anything that leads them to believe the issue is with the ESC. But I have ordered another ESC anyways, the 130 12s Tribunus, since 200 Amp is way overkill for this model!
The interesting item I am seeing is that the Scorpion Tribunus II+ 200 Amp ESC is still show BEC voltage with the BEC disabled, but was told by Scorpion that this is normal for the new generation Tribunus
The video is is just hovering around, not too exciting. I take a very cautious approach to flying, especially when seeing the un-commanded movement and would rather take the crawl, walk, run methodology.
Thanks to Will Parker who helped take the video at BARKS RC Flying field in Boise, ID today! I appreciate it.

Thank you, I appreciate it.

Would a hobbywing 130a esc be fine for this machine since I don’t do 3D just sport fly with a big loops and rolls lower headspeed? I’m in the process of building one but the esc is all I’m missing for it have everything else. Thanks

My sincere apologies. I must have missed this comment and sorry for the delay. I 100% know that a 130 amp ESC will work just fine with this model for the type of flying you are going to do, as that is the type of flying I do. I am pulling a max of around 70 amps depending on flight maneuver. So the 130 will be more then enough. The 200 amp ESC I have installed is way overkill!

Nice video. What is the head speed ? Normal and Idle Up-1 ?? Linear curve or sloped ? Pitch curve and range, pitch at half stick ? Thanks, Joe

I run a straight line throttle curve(s) for idle 1 at 50% and idle 2 at 60%. I use the governor in the Scorpion Tribunus ESC. With the 500kV motor and 9.33 gear ratio, I am setup for 1,350-1400 rpm for idle 1 and 1,600-1650 rpm for idle 2. The video was flown in idle 1. Pitch curve is linear from -100 - 100 with 12 degrees of pitch both positive and negative. Currently, for normal normal and idle 1 I run zero pitch until half stick and hover at 3/4 stick, which is around 5-6 degrees of pitch. I am setting up the helicopter to hover at half stick as that simulates my scale helicopters and this is used for proficiency. I hope this helps, and please feel free to ask any more questions!
