I have same problem with my Hubsan shell , it flies sideways and sometimes uneven level , this video u made helped me alot find wright issue with my quad . Thanks
Mark, please pay attention this message!!! I think I found out what caused the left yaw to my drone! I found a hubsan vid where it was saying to add some washers on top of a few screws under the B motors. I dissasebled the motors and I think I finnaly found the casue of the problem. The motorsb are screwed on top of 4 pads. Those pads have a ~1mm tall wall and the hole in the middle. I found out that two of the four pads's walls were ~0.3mm taller than the rest, cause the motors to have an angle. The washers aren't probably gonna work, because they add exccess height unless I find some of the excact height I need. I have the drone dissasebled now and I'm thinking of sanding those elevated pads. I'll see what I'll do and I'll try to update you.👍😂😂
Hey George. I am aware of what you are talking about. It's called shimming the motors. I looked at that, however I didn't mention it in the video. You need a micrometer to do it, but mine were okay. They didn't need to be shimmed, the actual shell was warped. I think I know why too. Here in Wisconsin, it is extremely cold during the very long winter months. However, I like to go out and fly whether it's cold or not. Sometimes it was so cold I had to stop because my fingers were getting frostbite. Anyways, flying the Drone around, when it is extremely cold, then getting into a warm car, can make plastic warp, from the sudden temperature changes. plastic becomes very hard and brittle when it is extremely cold, making it easy to break and so forth. When it's warm plastic has more flexibility. Going from the extreme cold to the warmth, may have distorted the shell on my quad. As for shimming the motors, there are very small shims you can buy, that are made specifically for that purpose.
Mark Suttner thanks!👍 I haven't flown it yet, I might do so soon. Ah, so the pads hadn't a problem to your quad. Reshaping the frame seems much harder than sanding 4 pads. Well done fixing it. (P.S. Waiting for a new vid of yours.)👍😂😂
Mark Suttner haha, I flew it yesterday! There is still some left yaw, but I think there's a big improvement. I think it's more stable as well. Maybe some more sanding under the motor pads will fix it.👍😂😂
Kinda but not exactly. Because this particular quad, has 2 "frames" (Upper & Lower Shell). If you only rely on the gap between the motor cowls and the upper shell, that is only showing you, that the upper shell is straight. The lower shell is the main frame, which holds the motors. If the lower shell, is twisted or distorted, the motors will be as well. So basically you need to make sure that both the upper and lower shells are straight and square. I was only using the Gap difference, as a reference. That is why I needed to use the square edge, level and the pitch & angle tool. Had to make sure that the Entire arm, both upper and lower were straight and square, that way the motor and props were as well.
Mark Suttner cool videos anyway mate. I have just got the s-s yesterday. Slight gap in one of the motors on mine but seems to fly good, so for that reason I will leave it alone. Seems a good little quad though. I ordered 2x spare batteries for the quad and the range extender kit for the transmitter
@@scottydrones2987 Thanks Scott :) As for the little gaps, between the motor cowls and the upper shell, I would not worry about it. They are not all going to be perfect. Flies Okay, leave it be. I have had mine for quite some time and that's why I had to fix it. Many, many flights with it. I also live in Wisconsin, where the weather is constantly changing. Sometimes I fly it when it is 0 degrees outside and then sometimes it's 70 degrees. Rapid temperature changes can make plastic warp. I believe that might be what happened to mine after time. I hope you enjoy flying your 501S ! Having the extra batteries will come in handy when you have a nice day to fly and want to keep flying. The extended-range kit will definitely help with your fpv reception and your control signals. Happy Flying my Friend ! :)
Mark Suttner I’m from the uk. It’s nice and cold here at the moment. This is my first quad after moving from rc cars. I’m just getting the hang of it haha. I had a little tumble yesterday with it but only broke a prop.
Hey Mark. WTH..... never would have thought the arms would have twisted like that. And almost un-noticeable ! You must have looked at your bird for hrs and scratched your head... lol. I don't think that I would have seen that slight difference. I WILL be doing an IMU and controller cal before my next flight. Thank you for your determination of solving this problem. Unbelievable !... lol
Are you referring to the regular first horizontal compass calibration? Or are you referring to the horizontal calibration where you pin the left stick, and toggle the right one?(Kinda like the IMU Re-cal), you just hold the stick a different direction, etc.
No, I did not. This imparticular quad relies on it's "Shell" as the Frame, so to speak. If the shell gets warped, then your propellers will also be out of alignment. In this case, I believe it was do to extreme Temperature changes, and lack of care. My fault. But it is still flying great, to this day. Only needing to replace a battery every now and then. But thats normal.
@@MarkSuttner so should I not buy this hubsan h501s x4 that's brand new in the box and under $100 ....this lady is giving it to me in an action I bid in and it will be under $100 to get it brand new in the box
I am just a couple of hours away from winning a bid for a brand new black version of the h501s it's brand new in the box for under $100 should I get it ......this videos makes me kinda scared to
Hey man great video but my issue is nothing like that but still i was hoping maybe you could help me out. So when i plug my battery in it starts its led sync expect my one arm blinks blue instead of white like the rest. Can't find anything on you tube that would help me out so I'm rolling around in comments. Link if you know a solution or need more info to help. Have a good day
@@MarkSuttner It would let me do the compass calibration. It appears when i completed calibration that all was fine expect the motor i was talking about blinks a different color. I have video but it won't give me controls at all so I'm not sure
@@roguerodent1105 So, you have Zero control over the quad ? Even after your calibration ? That could mean that you need to pair your controller to the drone. It could be, that somehow the controller is not paired with the drone, or became Unpaired, somehow. Do you have a picture on your screen ? FPV ? From the camera ?
@@MarkSuttner sorry for late reply but yes I do have video feed through my transmitter video feed. I'm still confused as to what the issue might actually be.
Thanks ! I am trying to decide, which quad I'm going to buy next. I have a Mavic Pro as well as the 3 Hubsan quads, ( 501S, 501SS and 109S x4 pro ) and a couple others. I was thinking about either another Mavic but instead of the Pro , I was thinking about getting an AIR. Seems like the Mavic Air might be more nimble and its maneuverability quicker, than the Pro. Plus it has rear obstacle avoidance sensors, unlike the pro. Don't get me wrong, I love the mavic pro, the video qualities it has, all it's functions, etc. It just seems like, from watching other people's videos of the mavic air, that it can do a little bit more. I'm not a big fan of even having the obstacle avoidance sensors because that is basically for new pilots, or maybe a RTH situation, where it might need to use the sensors. I don't know, there are so many quads that are moving towards the "mavic style", being portable and having folding arms and all that stuff, it's extremely hard to choose between all the different manufacturers and all the different quads. I guess it basically boils down to, what you want out of your drone, and what capabilities and functions it has. I love the mavic pro, it is an incredible drone ! It's nice that DJI, listens to people and their concerns and or complaints and then can fix that, with a software update. I just don't like having a smartphone or tablet as my screen and basically, being the controller. I know you can fly them manually with the control joysticks, but if you want any autonomous functions, besides RTH, you have to use you're smart device. It's not that big of deal. But I tend to like the controllers, where the screen is built-in and it does everything for you, you don't have to worry about OTG cables and plugs and stuff like that. Kind of like the Yuneec Hex. I would never buy that drone because it is a monster and it just doesn't suit my flying style, or any purpose I would have for it. However, the controller is a different story. It is a smart device & controller, Combined. Anyways, I'm trying to find another drone and can't make up my mind... Lol. Thx brother !
Mark Suttner I had a mavic air, very good in strong winds and in areas were nothing is around,but fly with friends or around wi fi areas you start to get problems, and noise, I sold mine.,parrot anafi looks good 👍🏻
The Cowlings were fine. Where did you see that, in this video ? It's pretty rare, to have a Brushless, Quadcopter Motor, become un-centered, because of the the cowls. Maybe more common,, with an RC Car Or Truck, that's 2 rotated on rough terrain. Not with Brushless Motors on Quad's. They are only serving 1 purpose of, to electomagnetize the motors, which are in a completely free "Airborne State". However, On a brushed motor, they can become un-centered, because of the Uneven wear of the brushes. I'm not even sure what you're referring to because the center of gravity on a quad is "almost" Perfect. In which the cowlings only provide lift by "Inducing" electomagnetic for the motors to spin. If anything would go "Un-centered", it would be the bearings. Not sure what you mean by that.
Hey Chris. My h109s kind of does the same thing if I am flying near cell towers. It seems like the 109s is really subcepteptable to outside interferences. I can literally fly it just fine, on one side of the park and on the other side, it seems like I lose control and it kind of starts doing what it wants as well. The park I'm talking about, has a huge cell tower directly in the middle. Even though those big panel antennas up their, face all the way around, I only get that really crazy flight, in some areas of that Park. Weird. Are you flying near Wi-Fi routers or cell towers, high voltage power lines or even urban areas like around houses and Wi-Fi routers?
Around my back yard and theres power line around. I have have flown in nature parks and no power lines around. The drone just starts to elevate and controler dose not bring in down.i have a bugs 3 pro and bebop 2 and they don't have that problem. I calibrate drones , controlers every time I fly so don't understand why h109s to me not flyable .
@@chrisricotta7063 Are you waiting for enough satellites before you take off? Are any of your switches, like return to home on accidentally? Did you bind the controller to the quad properly when you first got it? The h109s does not come paired, like the 501's do. Also, are you pointing your antenna to correct direction? The 2.4 antenna, should be slightly angled, pre nothched designed angle, to the left and sideways. With the tip pointing to the left, not at the quad. The tip of the antenna is the weakest transmission point, the middle of the antenna is where the strongest transmission comes from. You can not have control if the tip of the antenna is pointed at the quad....
@@chrisricotta7063 I forgot to mention one important thing... The controller that comes with the h109s, low and medium Edition, is the "H906A" . Those controllers are notoriously known for having a bad SMA to ipex cable inside the controller, for the 2.4 transmission antenna. For some reason, a lot of people get that problem. They can be tested and Easily replaced. This video might help -> ua-cam.com/video/VOn46KzOeyY/v-deo.html.
I have low edition and I have watch hours and hours of videos how to calibrate . The LCD screen will tell u if the RTH is on . Just watch the video u sent me and thanks for your help. Sorry just need to rant I paid around $400 for the drone and got extra batteries , have lipo in the controller, dji props for it and just don't fill comfortable flying it .
I think I know how your quad's arm got twisted! After checking my quad's arms, I put the drone back in it's box and I noticed that the arms could easily twist if you place the drone fast in the box, as the drone fits tighly in it and if you put it a bit tilted, the first arm entering the box might get a bit twisted.
@@QCGUY Question, "Hubsan QC Help & Support"... I understand why "Tekstra Brands Inc," , isn't giving Hubsan, the necessary changes, money and Research & Development Etc, to make these quads better. "Hubsan", is a Subsidary Company, that "should" have a lot more "$$", invested from Tekstra. I also understand why they don't give it to Hubsan. Anyone with a smart mind, can see the profit from selling, cheap, plastic "S**t", using retail stores. *Walmart*, Target, Etc. The list goes on and on. You'll Rarely find Any Hubsan products, or accessories, at a "Real" Hobbyists', retail Store. So, after many years flying Hubsan products, what is with the components ? Why is the company using the Cheapest Processors, Low Grade Modules and Restricted Chipsets? WHY ? Do you not have enough "Intelligent" people working for you ? I understand, that Hubsan is Absolutely known, for the Low Price. However, with a few minor changes, you could become a Leader in the market ! For example, instead of using a couple cheap, GPS Modules and a Geomag, for Trilateralization, which causes enormous "Wander", by the way. Why wouldn't you incorporate a slightly thicker shell, or a material that incorporates not only plastic, but some type of epoxy resin that will stiffen it ? Also, by adding a simple optical flow sensor and an extra processor, your Quad's "could" be like DJI quality. I'm not a hypocrite, and I know, everybody else knows, that "most models,",, of Hubsan, are a quad for the money. You could, easily and cheaply, add a few things, that would, slightly increase your production costs. But if anything, you would Gain more clientel and profit, by sales ! Because the quads would perform so much better. I'm not sure if I'm talking to the actual Hubsan Company...? Your name says "":::*". Ok, if you want some advice, take the Zino Off the Market ! Until you are able to get better processors, for about the same amount, stop making Everything Proptreitary and using the exact same basic platform for All your Quad's ! You may be making a profit now, if I were to have my say and intellectual knowledge into what goes into these quads, they would remain around the same price, however be 100% more reliable. Thanks for reading this.
Yehh makes sense it all must be level the frames at the motor end are very twisty and weak I had thought about making a stut brace going from each motor arm to stiffen it but I,m scratching my head it won't go onto compass calibration sequence when I power up all lights stay on except rear left that flashes, if I thought it was possible to strip all the crap inside and bin it and use the motors Esc,s and video card put in new flight controller and reciever run it with Taranis I will be going down that road
Thank you brother ! The video didn't turn out how I wanted it to. I actually filmed, Everything ! Using the heat gun to Straighten out the arms, etc. But, when I went to "Produce" the video, it said there wasn't enough room on my SD card. So, I went to delete No Longer Needed Pictures & Videos. Big Mistake ! I Accidentally/Unknowingly Deleted, the footage of fixing the quad !!!😐 So, I had to just settle for an "Explanation" type video, like this. I really wanted to show the actual footage. Oh Well ....
Hi, Mark it was a long way to solve the problem. My guess was a defective ESC module which would not always keep the speed steady. I found a video two days ago. It also shows a solution. But the problem is really the body shells. Over time, the body shells may deform due to the heat of the ESCs. I think that's the cause! I have a video here. ua-cam.com/video/bj5tKVa54Gc/v-deo.html another video shows a compass calibration ua-cam.com/video/A4YQ4b5IQtA/v-deo.html and this one shows another way https: // www. ua-cam.com/video/551XjOAQSGQ/v-deo.html In some video I've seen, someone had criticized the quality of the white body shells. There really seem to be differences to the black version. Maybe I still find the video. I'll take a look.
@@MarkSuttner the only reason why I say it's called dog tracking because we use that phrase in College and in the collision shop I am a collision specialist
Yeah, when I bought my quad and got it, I noticed that the motors had a small angle (not the shell). I think that's how it came even if I crushed it a bit when I tried to fly it in my house😂. I tried thightening some of the motor screws and loosing some others to make the motors perpendicular to the ground (I still have them like this, but they might have come out of their place after ~1 year). I also noticed that if I try to tighten all the screws the motors were getting an angle. About a heat gun, I don't have one, but I'll check condition of the shell and I might buy a new (if it's cheap), because it might fix the problem with the screws as well. About IMU calibration, my quad almost always does gyroscope and compass calibration when it turns on by default, I might try that as well though. I think I should just tell it to hubsan to get me a different shell as soon as I got (even if they had might given me a faulty one). Well done!👍😂😂
Yes, it's very common. I don't even think it's a fault / problem. It is kind of strange because my Original H501S, reads the quads voltage very accurately. However, my newer H501S-S, doesn't. I've heard the same thing, from a lot of people. So don't freak out about it. It's nothing to worry about. After you get a few flights under your belt, you will feel comfortable with your quad. And also, you'll know, how much flight time it will get, once your battery is at full potential. Flight times all depend on how you are flying the quad. The longest flight times are going to come from GPS hold, Steadily flying around. When you start going into altitude hold or even manual mode, the quad is a lot faster and it uses more battery power more quickly. I'm not saying to try altitude hold or even manual mode, they are extremely difficult. Altitude hold is a beast. Manual mode is made for, basically putting different propellers on it, for 3D acrobatics. That's not even what this particular quad was designed for, but people still do it. Trust me though, altitude hold and manual mode are extremely difficult to fly and I would not attempt turning off GPS, until you are very familiar with your quad and have had, at least a couple hundred flights.
@@MarkSuttner Believe me buddy... I will never be turning off GPS mode, but not sure if GPS is working correctly with my quad all over the place. As say, need a good calm daylight flight to test.
I have same problem with my Hubsan shell , it flies sideways and sometimes uneven level , this video u made helped me alot find wright issue with my quad . Thanks
Thanks, Man. Mine was twisted badly and would turn left. Straighten it out by just aligning the seams. Was about to buy a bnf. Thanks again.

Hi mark. So could it be heated up and straighten it by eye using the gap difference between the motor and the frame? Just a thought.
Kinda but not exactly. Because this particular quad, has 2 "frames" (Upper & Lower Shell). If you only rely on the gap between the motor cowls and the upper shell, that is only showing you, that the upper shell is straight. The lower shell is the main frame, which holds the motors.

Around my back yard and theres power line around. I have have flown in nature parks and no power lines around. The drone just starts to elevate and controler dose not bring in down.i have a bugs 3 pro and bebop 2 and they don't have that problem. I calibrate drones , controlers every time I fly so don't understand why h109s to me not flyable .
@@chrisricotta7063 Are you waiting for enough satellites before you take off? Are any of your switches, like return to home on accidentally? Did you bind the controller to the quad properly when you first got it? The h109s does not come paired, like the 501's do. Also, are you pointing your antenna to correct direction? The 2.4 antenna, should be slightly angled, pre nothched designed angle, to the left and sideways. With the tip pointing to the left, not at the quad. The tip of the antenna is the weakest transmission point, the middle of the antenna is where the strongest transmission comes from. You can not have control if the tip of the antenna is pointed at the quad....
@@chrisricotta7063 I forgot to mention one important thing... The controller that comes with the h109s, low and medium Edition, is the "H906A" . Those controllers are notoriously known for having a bad SMA to ipex cable inside the controller, for the 2.4 transmission antenna. For some reason, a lot of people get that problem. They can be tested and Easily replaced. This video might help -> ua-cam.com/video/VOn46KzOeyY/v-deo.html.
I have low edition and I have watch hours and hours of videos how to calibrate . The LCD screen will tell u if the RTH is on . Just watch the video u sent me and thanks for your help. Sorry just need to rant I paid around $400 for the drone and got extra batteries , have lipo in the controller, dji props for it and just don't fill comfortable flying it .
Thanks SOOO much! Ur the man! Got me flying again in no time 😁
I think I know how your quad's arm got twisted! After checking my quad's arms, I put the drone back in it's box and I noticed that the arms could easily twist if you place the drone fast in the box, as the drone fits tighly in it and if you put it a bit tilted, the first arm entering the box might get a bit twisted.
Good video 👍
Well, I don't work for Hubsan... Lol 😅, if I did, the quads would be 100% Better Quality. Anyways, Thank you !
Mark Suttner 🤔
@@QCGUY Question, "Hubsan QC Help & Support"... I understand why "Tekstra Brands Inc," , isn't giving Hubsan, the necessary changes, money and Research & Development Etc, to make these quads better. "Hubsan", is a Subsidary Company, that "should" have a lot more "$$", invested from Tekstra. I also understand why they don't give it to Hubsan. Anyone with a smart mind, can see the profit from selling, cheap, plastic "S**t", using retail stores. *Walmart*, Target, Etc. The list goes on and on. You'll Rarely find Any Hubsan products, or accessories, at a "Real" Hobbyists', retail Store. So, after many years flying Hubsan products, what is with the components ? Why is the company using the Cheapest Processors, Low Grade Modules and Restricted Chipsets? WHY ? Do you not have enough "Intelligent" people working for you ? I understand, that Hubsan is Absolutely known, for the Low Price. However, with a few minor changes, you could become a Leader in the market ! For example, instead of using a couple cheap, GPS Modules and a Geomag, for Trilateralization, which causes enormous "Wander", by the way. Why wouldn't you incorporate a slightly thicker shell, or a material that incorporates not only plastic, but some type of epoxy resin that will stiffen it ? Also, by adding a simple optical flow sensor and an extra processor, your Quad's "could" be like DJI quality. I'm not a hypocrite, and I know, everybody else knows, that "most models,",,
of Hubsan, are a quad for the money. You could, easily and cheaply, add a few things, that would, slightly increase your production costs. But if anything, you would Gain more clientel and profit, by sales ! Because the quads would perform so much better. I'm not sure if I'm talking to the actual Hubsan Company...? Your name says "":::*". Ok, if you want some advice, take the Zino Off the Market ! Until you are able to get better processors, for about the same amount, stop making Everything Proptreitary and using the exact same basic platform for All your Quad's ! You may be making a profit now, if I were to have my say and intellectual knowledge into what goes into these quads, they would remain around the same price, however be 100% more reliable. Thanks for reading this.
Yehh makes sense it all must be level the frames at the motor end are very twisty and weak I had thought about making a stut brace going from each motor arm to stiffen it but I,m scratching my head it won't go onto compass calibration sequence when I power up all lights stay on except rear left that flashes, if I thought it was possible to strip all the crap inside and bin it and use the motors Esc,s and video card put in new flight controller and reciever run it with Taranis I will be going down that road
Realey good mate nice
Thank you brother ! The video didn't turn out how I wanted it to. I actually filmed, Everything ! Using the heat gun to Straighten out the arms, etc. But, when I went to "Produce" the video, it said there wasn't enough room on my SD card. So, I went to delete No Longer Needed Pictures & Videos. Big Mistake ! I Accidentally/Unknowingly Deleted, the footage of fixing the quad !!!😐 So, I had to just settle for an "Explanation" type video, like this. I really wanted to show the actual footage. Oh Well
....
Nice review on the 501s DON
Hi, Mark it was a long way to solve the problem. My guess was a defective ESC module which would not always keep the speed steady. I found a video two days ago. It also shows a solution. But the problem is really the body shells. Over time, the body shells may deform due to the heat of the ESCs. I think that's the cause! I have a video here. ua-cam.com/video/bj5tKVa54Gc/v-deo.html another video shows a compass calibration ua-cam.com/video/A4YQ4b5IQtA/v-deo.html and this one shows another way https: // www. ua-cam.com/video/551XjOAQSGQ/v-deo.html In some video I've seen, someone had criticized the quality of the white body shells. There really seem to be differences to the black version. Maybe I still find the video. I'll take a look.
You just helped me.... I AM NOT GOING TO BUY IT... And when you said you see a cars ass moving sideways it's Called Dog Tracking
Its also called Crabbing
@@MarkSuttner the only reason why I say it's called dog tracking because we use that phrase in College and in the collision shop I am a collision specialist
Does this mean I shouldn't buy this one for under $100 that is brand new
It's one of the new black ones
Yeah, when I bought my quad and got it, I noticed that the motors had a small angle (not the shell). I think that's how it came even if I crushed it a bit when I tried to fly it in my house😂. I tried thightening some of the motor screws and loosing some others to make the motors perpendicular to the ground (I still have them like this, but they might have come out of their place after ~1 year). I also noticed that if I try to tighten all the screws the motors were getting an angle. About a heat gun, I don't have one, but I'll check condition of the shell and I might buy a new (if it's cheap), because it might fix the problem with the screws as well. About IMU calibration, my quad almost always does gyroscope and compass calibration when it turns on by default, I might try that as well though. I think I should just tell it to hubsan to get me a different shell as soon as I got (even if they had might given me a faulty one). Well done!👍😂😂
Hmm, I might try to tighten all the screws and see how it's gonna fly.
Why didn't I think it before?! Some spacer rings and some longer screws might fix it!
I wonder if it is quite a common fault... It has made me panic more now after my little heavy landing :o(
Yes, it's very common. I don't even think it's a fault / problem. It is kind of strange because my Original H501S, reads the quads voltage very accurately. However, my newer H501S-S, doesn't. I've heard the same thing, from a lot of people. So don't freak out about it. It's nothing to worry about. After you get a few flights under your belt, you will feel comfortable with your quad. And also, you'll know, how much flight time it will get, once your battery is at full potential. Flight times all depend on how you are flying the quad. The longest flight times are going to come from GPS hold, Steadily flying around. When you start going into altitude hold or even manual mode, the quad is a lot faster and it uses more battery power more quickly. I'm not saying to try altitude hold or even manual mode, they are extremely difficult. Altitude hold is a beast. Manual mode is made for, basically putting different propellers on it, for 3D acrobatics. That's not even what this particular quad was designed for, but people still do it. Trust me though, altitude hold and manual mode are extremely difficult to fly and I would not attempt turning off GPS, until you are very familiar with your quad and have had, at least a couple hundred flights.
@@MarkSuttner Believe me buddy... I will never be turning off GPS mode, but not sure if GPS is working correctly with my quad all over the place. As say, need a good calm daylight flight to test.
VERY Cool, Mark.
