you can also count the G force by dividing the velocity difference by the time of crash. Velocity was probably around 170 kph so around 47 mps, time was around one frame (probably less) looking at 30 fps youtube. We get 47mps divided by 1/30 of a second, so we get 1410 m/s^2 of acceleration which is around 144 G
I wonder if anyone asked Bobby, "are you OK?" and, "are these men bothering you" or "do you need me to call anyone for you?!" 😂 or "are these your daddy's" 😂😂😂
One thing I didn't make sure of when I bought my quad was how easy it is to find spare parts.. and it's not for mine, I have to buy an entire new frame if I brake anything.
@@Chillin-fpv they do that on purpose they do that here too with the T motor ft5HD. its kind of a starter prebuild 5inch drone, they have all kinds of stuff but not the arm, you have to buy it online elsewhere and pay huge shipping cost they want you to build one youself after that with frames they have and do have spare parts of
I just looked at the datasheet of the MPU-6000 and technically it can measure up to 16g but the MEMS component may be damaged by accelerations exceeding 10g. The datasheet warns that such accelerations could occur when cutting a chip from the spool it's delivered on.
@@gingerflow5594 it does actually, speeding too fast would cause your brain and your organs to come out of your body because they are in a liquid hold only by your vanes and nerves... Your spine probably would be broken too if not all your bones ;)
The three of you together are so much fun to watch! The FPV community is the tightest around! Great video, I will morn the loss of that quad forever! RIP
I did the math: Assuming the drone was at 75 meters high, which would allow it to accelerate to roughly 50 m/s while propelling itself downwards vertically. Also assuming that it took 0.1s to transfer its velocity from 50 m/s to 0 m/s. It would have pulled roughly 51 g's of deceleration. That is well enough to kill someone if exposed to for longer than one or two seconds at most. That is a similar number to what very extrieme car crashes are btw. (Due to inaccuracies, leave ~10-15 g-s of force to be accounted for)
Wait a sec… I WOULD have calculated out the complex figures too, but honestly did not want to offend any sensitive readers of this comments section. We have been indoctrinated by the mainstream media, news and the elites who now control the world, into believing that “Math is Racist”. Therefore, I now intentionally report the results of any complex mathematical computation as a drawing of a 🙂 “smilie face” or a 🙁 “frown”. 😉🤣
I'm pretty sure you can put G force in your OSD from your flight controller in betaflight... so maybe thats an option to get the data of crashing into concrete, by recording your DVR/OSD? Of course there will be a slight delay to transmission, which may be too long but maybe another option to explore. Thanks for this experiment and your quad Shawn ;)
I fly with my g-force on, mostly out of curiosity and not because I have anything on the quad with a low g-rating. Most boards can take upwards of 200g without significant issues, it's just a matter of the rest of the surrounding parts and loads. A super light wire soldered to the board may not be an issue at aerobatic g-loads, but in a crash it may have enough force to bend the board and break a trace or dislodge a component.
I had purchased this in my use on other channels. Pretty rad app, and if you have time I would like to chat more about the pattern features to include paramotoring :)
If I had to take an educated guess, I'd say your final impact was over a thousand G. The TPU GoPro mount and battery/tape amalgam probably had a lot more deformation than the aluminum and carbon quad frame, so it increased your deceleration time, but I can't imagine much energy attenuation before the rest of the rigid parts contacted. The bolts and spacers in the flight stack probably ate up a little more energy, but it had enough force to bend and break the FC within the flight stack, so it was still a crazy high amount of impact. That would be cool to repeat the experiment with a "shock watch" type G meter onboard as an additional analog collection device!
for general discussion . . . WHEN you are having to ADD POWER or goto higher power you are pulling more Gs . . . Gravity vs power (lift) is a fundamental discussion in anything at it relates to aerodynamics
you should try connecting to flight controller with ftdi adapter. downloading logs takes longer that way, but id sure like to see that log. This was fun to watch!
Bardwells look over at 1g his was one of the best videos in awhile. Between the editing of cut scenes, talk and fly balance and subject overall- loved it. Also love when bardwell is in the videos with Bubby. Great contrast of “screw it let’s just fly and have raw talent” (Bubby)…. And the “hold on let’s dive into the details” (bardwell)
Hands down you guys makes the best fpv Videos! 😍 it's so fun to see you all together while having fun with our hobby. please keep going i just love watching these videos! ❤️🤙🏼
The highest recorded g-force experienced by a human who survived was during the 2003 IndyCar Series finale at Texas Motor Speedway on October 12, 2003 in the 2003 Chevy 500 when the car driven by Kenny Bräck made wheel-to-wheel contact with Tomas Scheckter's car. This immediately resulted in Bräck's car impacting the catch fence that would record a peak of 214 G At Holloman John Paul Stapp made history aboard the Sonic Wind I rocket sled on December 10, 1954, when he set a land speed record of 632 mph in five seconds, subjecting him to 20 Gs of force during acceleration. The "record" far from 9G.😃
I was at Texas motor speedway when keeny brack ended up in the catch fence. That wreck was one of the scariest but never heard the g forces were that massive!
Looks like you guys were having some great fun... kind of one of the main points of this hobby. I have yet to produce a single video myself but I think I found a goodly second or 2 of this video that I can "review". Would be funny. Thanks for doing this, does go to show just how amazing these drones are and just how much punishments they can take, it is remarkable. Man, some of my old foam RC planes could not survive you even being mean to them, just look at them wrong and boom, a broken stabilizer or wing... and helis - they also don't take hits very well. Cool as heck, just a bit easier to damage. RC Cars can take a good hit, at least some can. I can't help but always feel it and say it - we are lucky as all heck and spoiled to have this kind of tech available to all of us, truly a gift as far as I am concerned as I started flying back aroun the late 70's - AM radios, about 1000ft range, NO Failsafes, run times of only a min or 2 on NiCd electrics, a bit better with NiMh. Batteries were heavier I think, power to weight definitely much better nowadays. One of my first planes had zero throttle control - it flew until it was out of batteries - very stressful but tons of laughs and fun with my friends back then. But one thing that I really like is that there is something for just about everyone - planes trains, cars, boats, even submarines... all very cool stuff. So glad you guys all had a fun day while the rest of us "suckers" are stuck in gray, drab office environments or gray, drab production environments, etc... I actually like what I do quite a lot but this would be better. Who knows what will be, but I do know this - get started asap if this is something that you want to to. Time is always ticking, and you will be surprised how hard that first win is, but how the second is just a bit different, and possibly easier, and so on... winning attracts winning and winners. Cheers.
You can get gforce indicator stickers that blow upwards of 200g. I am positive you will find them all broken no matter how you crash it. Instant g force from an impact is not even in the same universe as lateral gforces experienced in flight
In addition to Gs (acceleration, or the derivative of speed) you should also calculate and display "jerk", which is the rate of acceleration (or derivative of acceleration), which is also VERY important to know for humans being exposed to high variations of accelerations (the moment were the drone goes from 1G to 10G almost instantly would 100% kill you I guess). There is even a third term, "snap", which is the rate at which the jerk varies, or derivative of jerk.
I think i recall the mythbusters doing some tests on g forces ages ago i may be wrong but. Might be some answers there on what you pulled diving into the ground
I have been flying the tank for a few months and have abused this thing. Detroit bandos and a wreckless pilot havent killed this frame. It is as tough as advertised. 2450 kv on 6s and the weight doesn't really matter.
G Force setting in Betaflight OSD to DVR? that would record everything until system failure. Been meaning to play around with it when I get a chance myself, but haven't had a chance. Hadn't intended a full power crash to test it though....
Fun thing is that i did this just last week for a school project. Didnt hit the ground tho 😅. We used tape to strap a phone on my quad and well it worked but the data was horrible because of the app. Got around 5g just straight up acceleration, so pretty accurate for a cinewhoop apparently!

Nice. But when it comes to pullin' gs on a regular basis, there's only one champ: the Peregrine Falcon. That bad boi pulls ~25g when coming out of its stoop. Twenty-five gees. Incredible.
This is one of the best videos I’ve seen in a long time, Shawn Morrison, your tank is a beast, such an amazing validation of your build it is the ultimate basher kwad💥 #TANQIsTheUltimateKwad 👏👏👏
This was some nerdy awesome fun to watch! A cool followup to this would be to setup a high jump mat or some matresses and fly as fast as possible into that. You'd get your G's but the deceleration would be less intense and maybe it'd save the fc or the gopro datalogs. These things are so fast and overcome the 1g from gravity so easily that horizontal G's into a mat would be pretty much as high as a vertical acceleration into the mat. Horizontal may be easier to aim too.
less intense deceleration means less g, that being the definition of , so you wouldn't get the same g with a mat. acceleration or deceleration is change in speed, gravity is a change in speed of 9.8m/s/s, 2 g is double and 3g tripple. nice thought though
@@doccock100 I agree, however maybe one could still get a really high G count, way above regular flying, near the envelope.... only the equipment survives enough to extract some data. You're not at asphalt parking lot G's, but damn close to be sure.
This week a one fellow asked if he can build a four inches quad with 1404 motors to fly with a 3000 mAh bat. He did the calculations based on the Iflight motor table. And he did not get why I say it will not fly at all. This video has opened his eyes 😂🎉 The mass and the weight are two different values and the weight depends on the G force.
I activated an osd feature in betaflight on my quad that show me live g's and the max g's at the end. I typically get around 6.5 g's with normal flying, with my max being at 11.5 g's (but I'm not sure if it was during a hard landing or actual maneuver).
I know without the battery clamp on the avata the battery flies out on fast hard turns. I think you got 25G's on that impact with the ground. But awesome science experiment.
it was fun! now the main question: what's the most durable drone from rotor riot? given how many drone did I break (well, all of them actually) it would be great to finally buy something THAT dureable like on the video.
1 G is 9.8m/s squared so if your quad was going 200kmh (56m/s) and then hit 0 in 0.3 seconds (hypothetically) then it decelerated at a rate of 66 / 0.3 which is approx 185m/s squared which divided by 9.8 is around 19Gs :)
It’s probably much more tho cause it loses all its speed in like 0.1 seconds so you could triple that number and still be in the ballpark, like 60Gs or so
Depending on the speed at impact, this instant deceleration can easily exceed 1000+G. You can do the math yourself. The moment you add a time of deceleration smaller than 0.5 second, the G-force gets through the roof. The most extreme race car crash pulled 214G and the driver survived. The deceleration happened in seconds, not milliseconds.
MOst of that is correct, but the indycar crash did not happen in seconds, it slammed the wall backing in, yes the crush box did its job and slowed the impact, but I am pretty sure it was under 100ms, not seconds.
@@user-rs8zg8ey2b I think we have to define what deceleration is. He didn't come to a stop in 100ms. Even though his car was smashed into pieces in a very short time it needed seconds till his crush box came to a rest. If he had stopped in 100ms, he had not survived this crash. The shallow angle of impact is key here.
@@user-rs8zg8ey2b The angle of impact is what matters. The more shallow, the longer the time of declaration. There is someone who survived falling out of an airliner at cruise altitude! Why? Because she landed on a steep hillside. With it, the time of declaration got longer. The falling speed was transferred into a fast decelerating sliding motion. If you hit a wall head on, there is no sliding. A sudden stop. Did his crash box made a sudden stop? Absolutely not! It was sliding with him many meters over the racetrack before coming to a rest. 214G was the short spike in G-force he experienced an impact with the railing. Was it a violent impact? OMG, it was! Still, it could have been much worse.
Well you can estimate the G forces on the impact, that being said with a lot of assumptions. As far as I know, fpv drones can go above 100mph, let's say that is about what you were doing at the time of impact. You can see about 2 frames of the impact in the video, the first one on the ground and the second as it already bounces up. I'd say the impact itself took about half a frame (possibly less) a= (v-u)/t - I assume u is 0, so we can take it out of the equation g= 9.81m/s^2 So, v =100mph = 44.7 m/s t = 1/30s * 0.5 = 0.0167s a = 44.7m/s / 0.0167s = 2676.6 m/s^2 = And there you have it. I would say the average acceleration you pulled during the impact is roughly at Though I wouldn't be surprised if at peak during the impact it was in the thousands. If you have any more accurate data, feel free to substitute into the equations and share what did you get. Great video guys!
you can also count the G force by dividing the velocity difference by the time of crash. Velocity was probably around 170 kph so around 47 mps, time was around one frame (probably less) looking at 30 fps youtube. We get 47mps divided by 1/30 of a second, so we get 1410 m/s^2 of acceleration which is around 144 G
Can't believe it took me this long scrolling down to find the guy who paid attention in physics in primary
Imagine walking nearby and seeing them laughing at the drone flipping in the air 😅😂😅
JB's laugh geeks hahaha
which makes no sense to others but some for reason very funny to drone pilots. hahaha

First time I heard JB like this 🤣
Love it.
Gotta call the drone bully officers

Bardwell’s laugh is so manic
@@grandpa_stanley7813 He laughs like he's getting away with being happy in North Korea! It's awesome lol
The sound the quad was making was literally ticklish 😂
5:00 Bubby has a smooth style that I love. Less about how fast can it be done, more about how much can it flow.
I'm not sure what's funnier, the 2000 rate flips, or your guys laugh from it🤣🤣
You can just let the G forces display in the BF OSD btw but should be nothing new to you 😉
That's exactly what I was thinking. I literally have always had the G up in the left corner of my osd.. form at least 5 years ago.
Did they really not mention that in the video? That means this is a commercial then 🤡🤡🤡🤡
They’re definitely flying hd. Maybe these osd features aren’t available there? Idk I only fly analog and I have max g force in my post flight info.
There is full osd elements on any hd systems, lol. Surprisingly the don’t know it. They went hard way with the GoPro😅
@@nogod4me_fpv Not just hard way, if that's GPS only, those g-forces will be WAAAAY off...
I can't believe how durable those quads are! That's insane
carbon fiber,
same strength as steel [not as dense], one fifth the weight!
Yeah can be surprised I finally broke an arm on my newest frame, but after taking plenty of abuse before hitting the tree finally did it
One thing I didn't make sure of when I bought my quad was how easy it is to find spare parts.. and it's not for mine, I have to buy an entire new frame if I brake anything.
@Greg's tow life yeah specially for cheap Chinese frames I did that on my first quad. I really like the tbs source frame since it's cheap and durable
@@Chillin-fpv they do that on purpose they do that here too with the T motor ft5HD.
its kind of a starter prebuild 5inch drone, they have all kinds of stuff but not the arm, you have to buy it online elsewhere and pay huge shipping cost

This right here is the reason I love FPV!!! Three grown men (you too Bubby) giggling like children just having the most fun ever!!!!
Accelerometers saturate eventually, most only go to 10G. Also, the best way to have a big acceleration is to change direction or to hit something.
I just looked at the datasheet of the MPU-6000 and technically it can measure up to 16g but the MEMS component may be damaged by accelerations exceeding 10g. The datasheet warns that such accelerations could occur when cutting a chip from the spool it's delivered on.
They did hit "something" (i.e. GROUND)
speed never killed someone , sudennly becoming stationary is the problem =D
Kids will be kids lol love it

I did the math:
Assuming the drone was at 75 meters high, which would allow it to accelerate to roughly 50 m/s while propelling itself downwards vertically. Also assuming that it took 0.1s to transfer its velocity from 50 m/s to 0 m/s. It would have pulled roughly 51 g's of deceleration.
That is well enough to kill someone if exposed to for longer than one or two seconds at most.
That is a similar number to what very extrieme car crashes are btw.
(Due to inaccuracies, leave ~10-15 g-s of force to be accounted for)

Just kidding, of course!
Or are THEY kidding? 🤔🫣🤣
There's something very satisfying about seeing a screaming drone slamming into the ground like a meteor.
I'm not even mad we didn't get the number because smashing the drone was so fun.
This is by far the best thumbnail on RUclips right now.
I've always wanted to flip upside down and then full throttle straight into the ground. I'm glad you did it.
Learning to fly line of sight and flipping will normally end up doing exactly that at some point! Ask me how I know.....
Felt compelled to comment to give @BubbyFPV props on his first rip in this video. That was some awesome flying dude!

You'd get your G's but the deceleration would be less intense and maybe it'd save the fc or the gopro datalogs. These things are so fast and overcome the 1g from gravity so easily that horizontal G's into a mat would be pretty much as high as a vertical acceleration into the mat. Horizontal may be easier to aim too.
less intense deceleration means less g, that being the definition of , so you wouldn't get the same g with a mat.
acceleration or deceleration is change in speed, gravity is a change in speed of 9.8m/s/s, 2 g is double and 3g tripple.
nice thought though
@@doccock100 I agree, however maybe one could still get a really high G count, way above regular flying, near the envelope.... only the equipment survives enough to extract some data. You're not at asphalt parking lot G's, but damn close to be sure.
youre right that it would probably be the safest way to get a very high reading
@@nexgenRC that parking lot impact was 100+G easily, its not how fast you go, its how fast you stop.
😂😂 5:39 Bardwells Face When bubby hit the entrance pipe Gap 😮😂 Bardwell was like i know that sheet wasnt on purpose 😅
This week a one fellow asked if he can build a four inches quad with 1404 motors to fly with a 3000 mAh bat. He did the calculations based on the Iflight motor table. And he did not get why I say it will not fly at all. This video has opened his eyes 😂🎉 The mass and the weight are two different values and the weight depends on the G force.
Also should Try Power Flips. I bet it would max the G counter out..
Damn!! Little homie has become quite the impressive freestyle pilot! It’ll be interesting to see where he is in two years compared to the rest of ya.
You da best drone channel keep grinding with the content.thats go bubby fpv
The sound of that drone slamming into the ground makes my soul cry.
I activated an osd feature in betaflight on my quad that show me live g's and the max g's at the end. I typically get around 6.5 g's with normal flying, with my max being at 11.5 g's (but I'm not sure if it was during a hard landing or actual maneuver).
Fantastic video was fun... Bardwells laughing was the best, made my night... 😂
Any link for that green zorro? Is it a skin on top?
That video was so fresh and creative. I really liked it! Awesome!
This was hilarious fair play!
You guys are nuts. I love it.
I know without the battery clamp on the avata the battery flies out on fast hard turns. I think you got 25G's on that impact with the ground. But awesome science experiment.
That crazy rates laughter is infectious.
Another nice episode! 👌
@bubbyfpv Can you share your rates please? Really need to try these out.
it was fun! now the main question: what's the most durable drone from rotor riot? given how many drone did I break (well, all of them actually) it would be great to finally buy something THAT dureable like on the video.
amazing G-force review
Behold, EVIL BARDWELL. YOU'RE NOT GOING TO LEARN SOMETHING TODAY!!! 13:46
Answer to all the questions.
G= All of them!
14:10 bro those laughs sound so goofy
Best video! The laughter was contagious
1 G is 9.8m/s squared so if your quad was going 200kmh (56m/s) and then hit 0 in 0.3 seconds (hypothetically) then it decelerated at a rate of 66 / 0.3 which is approx 185m/s squared which divided by 9.8 is around 19Gs :)
It’s probably much more tho cause it loses all its speed in like 0.1 seconds so you could triple that number and still be in the ballpark, like 60Gs or so
Lot of Fun !!!
I came here cause the thumbnail was funny :)
Oh that makes me so happy me and @lehanvander spent like 5 hours working on it 😂
@Bubby FPV lmao well it is a very good pic so yeah. And great video too 👍
Yay
Great video so much fun ❤❤❤
Depending on the speed at impact, this instant deceleration can easily exceed 1000+G. You can do the math yourself. The moment you add a time of deceleration smaller than 0.5 second, the G-force gets through the roof. The most extreme race car crash pulled 214G and the driver survived. The deceleration happened in seconds, not milliseconds.
MOst of that is correct, but the indycar crash did not happen in seconds, it slammed the wall backing in, yes the crush box did its job and slowed the impact, but I am pretty sure it was under 100ms, not seconds.
@@user-rs8zg8ey2b I think we have to define what deceleration is. He didn't come to a stop in 100ms. Even though his car was smashed into pieces in a very short time it needed seconds till his crush box came to a rest. If he had stopped in 100ms, he had not survived this crash. The shallow angle of impact is key here.
@@suesun7072 yes, the sudden decel is where the peak G's happened, and that is the 1st wall contact, everything else is less Gs.
@@user-rs8zg8ey2b The angle of impact is what matters. The more shallow, the longer the time of declaration. There is someone who survived falling out of an airliner at cruise altitude! Why? Because she landed on a steep hillside. With it, the time of declaration got longer. The falling speed was transferred into a fast decelerating sliding motion. If you hit a wall head on, there is no sliding. A sudden stop. Did his crash box made a sudden stop? Absolutely not! It was sliding with him many meters over the racetrack before coming to a rest. 214G was the short spike in G-force he experienced an impact with the railing. Was it a violent impact? OMG, it was! Still, it could have been much worse.
@@suesun7072 I agree with all that, just not 214Gs was over seconds or even 1 second, that peak impact was easily under 100ms.
Thank you for doing this FOR SCIENCE!😂
Well you can estimate the G forces on the impact, that being said with a lot of assumptions.
As far as I know, fpv drones can go above 100mph, let's say that is about what you were doing at the time of impact.
You can see about 2 frames of the impact in the video, the first one on the ground and the second as it already bounces up. I'd say the impact itself took about half a frame (possibly less)
a= (v-u)/t - I assume u is 0, so we can take it out of the equation
g= 9.81m/s^2
So, v =100mph = 44.7 m/s
t = 1/30s * 0.5 = 0.0167s
a = 44.7m/s / 0.0167s = 2676.6 m/s^2 =
And there you have it. I would say the average acceleration you pulled during the impact is roughly at Though I wouldn't be surprised if at peak during the impact it was in the thousands.
If you have any more accurate data, feel free to substitute into the equations and share what did you get.
Great video guys!
