I’d like to see under a high speed camera, the air flow between the upper and lower props with some type of smoke. Since the air flows downward, putting smoke in top to see the the air path would be cool. It’ll be like seein a bullet being fired under a high speed camera, different prospective.
@@uavtech I have a an X8 cinelifter with BH 2810 1500kv and HW 60A 4 in 1 ESC and 7 inch props AUW = 3800gr . Can I do the first flight test with the stock PID?
Was going to say about the FPV feed camera having jello, having at a fixed angle/rigidly mounted could help out with that. I know this is comparing apples to oranges (5" 6s Racer vs a giant X8 octo camera rig) but the further out in my case with the FPV camera on TPU with an adjustable FPV camera (able to change angles on the fly) I will see jello at high throttle or if I get mildly beat up props. Recently I started doing fixed camera angles and changing the infill percent on the 3D printed camera mounts and it helps a lot. The only way I get jello now is if I have very thrashed or completely missing blades on the props due to BF doing everything it can to try and keep the quad steady. Point I'm trying to make is the further out something is mounted or is not rigid enough, the more oscillations you can get depending on what it is (camera mount, or say a 800mm xclass rig for instance that is not rigid for arm mounting.) Not always a bad thing (hybrid configuration for instance, 5" arms up front with 6" arms on the back for a 5" racing quad for handling) but something to keep in mind. Great video as always!
I have a question, since we have a 2 props per arm, which are rotating on opposite direction, that means that there is about 0 reactive moment per arm, so when you give 100% throttle, there is about 0 N/m of force on arm, since props are compensating turning momentum of each other, but doesnt BF designed for the quad where each arm will have a 1 prop, where on higher throttle arm will have a higher N/m turning momentum ?
You have to tell the Mixer it is an octocopter in the Configuration tab. That sets up the Mixer to handle things differently. You also tell it specifically on 4 arms. However, that counter momentum concept is the same regardless of motor layout on an octocopter.
That looked easier then my 10inch 🙈 but that hat a defective gyro and freaky esc Which rates do you use? Did you balance the props? On bigger biblades this is a must have !!!
Hi, I build x8 7 inch with 2508 motors and only 4 motor outputs with the upper and lower props spinning the same direction, All the other x8 builds i see use 8 motor outputs and counter rotating props , I feel my way is easier to tune. And i know for sure if i loose a prop or 4 it will still fly. Can you please try tuning this config without setting up counter rotating props, I think you will be surprised. Cheers
I had to ship for customer. Interesting idea! Tuning is the same though. Same core methods. So you really don't have an octocopter, or specify it as such in the mixer. You have a quad just with 8 motors.
@@uavtech Yes you could call it an 8 motor quad , i have some vids on my yt channel if you would like to see how they fly, All tuning follows the same principals
On Yaw? Because the tracking is not that bad. I did turn down to 60 i think (windup). On Roll and Pitch, i-Term Relax (aka i-Term Clamping in PID control) to the rescue!! A amazing add by Joe Lucid!!
What do you think about ichabod LR frame by shendrones? I have actually iFlight XL7 and have lot of noise on gyro and strong jello on hd camera. Shendrones frames has so thick arms and it looks good.
Some thing must be wrong with my transmitter, when I flick the Arm switch some girl says "Oh no you didn't..." When I disarm she says "Well that didn't suck at all!" Maybe I got a bad one.

"Im UAV Tech, do you have a moment to talk about our Lord and Savior Blackbox logging?"
Love your stuff man, the inner geek is smiling :)
It's like a drug, its just so good!
Great Video, Top Expert!!
Casually doing rolls with a three pound rock strapped on lol.
At 800 deg/sec!
I give it to you man this is a first haha Shendrone Thicc wow
Shes a tank! Could have some fun with that payload capacity.
wonder why biblade? Great Vid Mark
longer flight time. But tri-blades will likely be smoother if you have THICC.

Thanks for the video. Did you do your first flight with the stock PIDs as you show?
no, stick KISS pids video is: ua-cam.com/video/8c9ggTbWrM8/v-deo.html

I've looked everywhere and all the big online stores are out of stock on that rock.
I have one if you want to buy. Lol.

@@uavtech is there an individual pwm outputs for each esc? Or there is only one per arm?
Per motor. So 8 ESCs.
Any chance the jello is from the bi-blades?
They don't help for sure
What motors are you running on this?
2806.5
@@uavtech Thanks :)
Huh? No watch.. how could you look at the time 🤔
Anyway this was helpful for big quad owners 👍🙂
That looked easier then my 10inch 🙈 but that hat a defective gyro and freaky esc
Which rates do you use?
Did you balance the props? On bigger biblades this is a must have !!!
No balance. HQ seems very decent. Actual Rates - 800 dps
UAV Tech
Thats impressive this thing stopping 800 deg/s flips without the motors saturating
@@jas-FPV yup!
UAV Tech whats the dshot idle value and do you use dynamic idle ?
8 or 10 percent Dshot Idle.

Depend how hard u push it. Maybe 5-min?
Well that's a cliffhanger. Luckily I'm a patreon :)
It will be public release this one.

How thd hell did you not have INSANE bounceback without turning iterm windup all the way down??
