Tuning a 4,300-grams Drone - Shendrones Thicc 😱💥

In this video, we take a look at tuning the Shendrone Thicc. We give her a 5-lbs payload then scale it back to a 1.5kg (3.3-lbs) payload for the final tune as an analog of the camera weight.

What a beast of a machine

[@DAFPV]

"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 :)

[@uavtech]

It's like a drug, its just so good!

[@tehllama42]

Mark's Rocks get better adventures than most people's GoPros. Change my mind.

[@macelius]

Casually doing rolls with a three pound rock strapped on lol.

[@uavtech]

At 800 deg/sec!

[@felyfpv7710]

Great Video, Top Expert!!

[@davesfpvfiftyfiveco.7716]

I give it to you man this is a first haha Shendrone Thicc wow

[@chrisyoung8062]

I've looked everywhere and all the big online stores are out of stock on that rock.

[@uavtech]

I have one if you want to buy. Lol.

[@mikehunt2667]

@@uavtech careful I put a patent on those

[@prozay6856]

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.

[@ChainsawFPV]

Shes a tank! Could have some fun with that payload capacity.

[@h2o-fpv623]

great video thank u

[@Quadcopterguide]

wonder why biblade? Great Vid Mark

[@uavtech]

longer flight time. But tri-blades will likely be smoother if you have THICC.

[@boactech3076]

Huh? No watch.. how could you look at the time 🤔 Anyway this was helpful for big quad owners 👍🙂

[@BikeGuyFPV]

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!

[@QuickCookie]

Thanks for the video. Did you do your first flight with the stock PIDs as you show?

[@uavtech]

no, stick KISS pids video is: kzbin.info/www/bejne/bpScmJqKl7ylg5o

[@QuickCookie]

@@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?

[@recon_fpv]

Great video. Nice rock! What is that app are you using to configure from the phone? Also what cable is that, an OTG?

[@recon_fpv]

MarK! I just found your video from June, thank you! You are a god among mortals.

[@uavtech]

Lol, I wish!

[@kwadkenstine4988]

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

[@uavtech]

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.

[@kwadkenstine4988]

@@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

[@fpv_am]

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 ?

[@uavtech]

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.

[@fpv_am]

@@uavtech is there an individual pwm outputs for each esc? Or there is only one per arm?

[@uavtech]

Per motor. So 8 ESCs.

[@RubyS.1]

Well that's a cliffhanger. Luckily I'm a patreon :)

[@uavtech]

It will be public release this one. Tuning details -- > Patreon. THANKS FOR THE SUPPORT BTW!!!

[@jhughes2286]

Any chance the jello is from the bi-blades?

[@uavtech]

They don't help for sure

[@jas-FPV]

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 !!!

[@uavtech]

No balance. HQ seems very decent. Actual Rates - 800 dps

[@jas-FPV]

UAV Tech Thats impressive this thing stopping 800 deg/s flips without the motors saturating

[@uavtech]

@@jas-FPV yup!

[@jas-FPV]

UAV Tech whats the dshot idle value and do you use dynamic idle ?

[@uavtech]

8 or 10 percent Dshot Idle.

[@flaparoundfpv8632]

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

[@uavtech]

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!!

[@ArbeeAerials]

What motors are you running on this?

[@uavtech]

2806.5

[@ArbeeAerials]

@@uavtech Thanks :)

[@DraveS21]

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.

[@jankryca6543]

What flight time are you getting?

[@uavtech]

Depend how hard u push it. Maybe 5-min?

[@choppergirl]

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. Working on an automatic FPV flossing flying robot today: Tie floss string to rubber band and hook over doorknob, tie other end of floss to robot, insert teeth and kick back and watch Golden Girls. kzbin.info/www/bejne/d6KxmXdrpr2Sprs My first 6s home brew bottom mount 21700 liion battery this week, what a bunch of !@#$% solder points: air-war.org/graphics/Battery02b.jpg You guys insist on those insanely high rates, you lose a lot of precision and resolution around the center of the stick... must be a whiplash headache inducing flippy floppy hard snap roll robotic feel guy thing. I finally figured out super smooth rates that suit me, tailored for zipping around golf course tree trunks and grass ocean English Country gardens... Roll: 0.24/0.83 /283 Pitch: 0.28/0.85 /368 Yaw: 0.22/0.74 /169 Cam angle for however fast I'm flying, so mostly, 45: 15-30-42-45 Don't want to land blind from high camera angle any more... bump that.

[@uavtech]

Nice. It not tried already, check out Actual Rates. They give you both for control (Sensitivity = 10). Squish and fast too.

[@jorgeromero4680]

whaaat are you tuning for Nurk? 😲

[@uavtech]

Whelp, kind of. Lots of the guys used my previous Thicc tune. This one is hitting Johnny.
