Sorry, I'm not sure about this. Normally if battery too weak, the drone blade will rotate but won't allow to fly up.

Can try troubleshoot it by replacing another battery or try fully charge the drone battery

It need to make sure the article is published and depend on publisher have linked with Google scholar. Else, need manually add to our profile. If very new published article, need take within 2 week to appear in Google scholar.

Follow the video guideline, should be fine. Cheer

But the drone video recording quality not that good.

Welcome

Hi, at result need to key in equation VSWR =(1+mag(S11))/(1-mag(S11)), the plot this graph VSWR vs frequency

I will create a video for you how to show VSWR

Hi, Welcome. The loss of waveguide in the video is 0.0235dB/50mm, but is at 9 GHz. From the data sheet that in 1:05min, the max attenuation value is refer to center frequency of the waveguide, 10 GHz. That is common for e.g WR62, 12.4 to 18 GHz, the attenuation in data sheet will refer to 15 GHz. You may download the CST file from my video description, and run the simulation then check it at 10 GHz, loss 0.005dB/50mm. you will get approximate to the 0.1dB/m attenuation. if you have better recommendation solver or method, please share to us too. 🥂

Yea, equip with 2 unit rifle, left and right hand.

@@ichini3793 Hi, if you mean using the Skydroid receiver. Yes, it will extend, because the skydroid had the extended antenna. Can also change the antenna to support longer range.

@@robertstane5823 Hi, I think the app so far is used for E99 pro2 camera viewing and recording. Can't use the app as remote controller for E99 pro2. My side also can't make it.

@@LYSStuff Thanks for responding mate... The app I downloaded was specifically for the E99 Pro and it had all the proper controls on the cell phone screen. But it didn't connect. The instruction sheet QR stated "QR code not valid" I noticed there are several e99 apps at Play Store. Do you know the right one?

@@robertstane5823 Hi, I only tried with KY FPV app as shown in the video. But KY FPV although shown all the controller, but it not able to control, but it able to display the video from drone E99 Pro.

@@LYSStuff I found it! The drone came with a QR that didn't work. So, I searched play store using all kinds of possible titles. It turned out to be RC UFO. The E99 K3 Pro might be more of a toy that a real drone. I'm looking at the new DJI NEO to possibly buy for a more professional drone. Thanks again for all you help... Robert

@robertstane5823 wow, nice. Thanks for the information. 🍻

@@LYSStuff I have e88

Nice, almost same functionality

@@LYSStuff it works properly

As long you have your tensor material dielectric properties, then just define as your new material

If you do not have your tensor material dielectric properties. Then you need to measure it using dielectric measurement, then use the measured value and define in CST

Hi, I'm not sure what do you mean 'normal setting'. To download some China version app, require to change the iOS region to China Mainland.

@@LYSStuff like in the app settings

Can't, if you download international bilibili version. Change setting or language will not change the app to China version. Is totally 2 different app

@@LYSStuffI think the person is asking whether the language can be changed in the Chinese bilibili app since they can’t understand Chinese

I see, can't change the language in China version Bilibili app

Hi, I just saw your email. You may refer to this video for Yagi antenna design ua-cam.com/video/XsnNBoEJJz8/v-deo.html. using the calculator in the description to get the initial dimension. Then, adjust the dimension to meet your specify frequency.

@@AmanShekhar-f9m Hi, Yes, you can

Hi,you need to turn one the drone 1st and only search for the WIFI

@@laibabeig3780 please refer to the calculator in the description.

Welcome, you may refer to this video how to manual add your article. ua-cam.com/video/Aei40_Dqpt8/v-deo.html. Based on my experience, some new accepted article require some time to publish and detect by Google scholar. Might be 1 or 2 week after your article published by publisher

@@Itz_Zan-0 yea, we can calibrate it using the remote control

@@Itz_Zan-0 must calibrate to make it more stable

Can, as long able to ouput 7.4V and above

Guys please check out how to design helical antenna on CST, very interesting...

Welcome

Hi, can't. Because owner disable others to download it.

For your case and setup is not with metal backed plate. You cant use this calculation and also you have no permeability and permittivity value. You should just use the equation of Absorption = 1 - s11^2 - s21^2. S11 is you reflection of the material, you may refer to this video ua-cam.com/video/vae_nMPVOSA/v-deo.htmlsi=zeUU8wL0mFtulq2f

@@LYSStuff we make a material with PDOT and MCWNT(carbon nano tube) you say it our material is conductive and absorbs the EM waves. We find out S11 and S21 parameters for different frequencies and experimentally right? our material is new we don’t know its permeability and the permittivity and loss tangent when defining a new material in the simulation. How we can find out these things. Could you refer me some video or can tell me formulas? Because when finding the permeability and permittivity we need to use reverse algorithms and formulas. And it also contains Cos^-1 (cosine inverse function) so how we will be sure our permeability and permittivity is accurate and will give us accurate values to match the experimental and simulation values. I will be very thankful if you can guide me on this.

@usamatahir1353 yes, try to use NRW method to calculate material properties from you S11 and s21. But if your method of measurement is incorrect (without proper calibration such as TRL or others factor like distance define) , then the results will looks weird.

@@LYSStuff yeah this is what i think. Thanks for reconfirming about NRW method. I was confused about the method. Thanks have a good day. And keep in touch. I am happy you share your thoughts.

@@mikulaschaloupka6589 Just accept the WiFi with no Internet access. The Drone WiFi just for your phone sky fpv app connect/communicate with the drone. Then your phone Internet will witch to you mobile data, because phone WiFi is used for connect with drone WiFi. No worry

Wait and does the WiFi name need to be DU-HD4K-and numbers?

@@mikulaschaloupka6589 yup, you may refer to your manual guide. It should got mention the WiFi number

I'm so sorry that Im asking that many questions but when I try to join the WiFi it says No internet and when I have my hotspot on it disconects from the drone WiFi. And even when I have the drone WiFi (in the app there is still nothing.) I dont know where is the problem. And I think that on the Camera there is a cover.

@mikulaschaloupka6589 the camera cover you need to remove it, eye the camera lens is blocked by the cover/sticker
