SJRC F11 Pro 4K & Controller After Mods Tests
Вставка
- Опубліковано 19 вер 2024
- Today, I perform a short flight and hover tests to see how well the mods that I've made to the drone and controller, truly work and even though I stayed fairly close by, unlike prior to any modding, I didn't have anymore lost gps connections that would cause the drone to toilet bowl out of control, nor loss of video feed, nor did I get the dreaded error message telling me to open the prop arm because it was blocking the gps signal. Solid connection and reliable video feed! Next testing will be in Sport Mode and range test...stay tuned

Hey, check out the products I am selling on Amazon - www.amazon.com...
Thanks for the mod video. My f11 arrives tommorrow. From what I have seen on various channels it is neccessary, if you are a range junkie like us (Fimi 2020, 16,000 ft solid signal).Cheers bud, will check back.
Thanks for sharing
Cool man
I'm still looking forward to see the improvement in longer range of the fpv signal. As for the GPS mod, I doubt it makes a difference, you still have the toilet bowl effect around 7.6 minute mark. Today is a great day to fly, at least near New York City area. Weather is calm, visible satellite is 12 or more. My unmodded F11 Pro 4K flies beautifully, upto about 1650 ft before losing FPV. No toilet bowl whatsoever even when it hovered about 6 ft above ground. When no GPS signal strength shows up, close the app, and open it again, more than often it'll show.
When no gps signals are showing, that's when the craft, toilet bowls and that's when you get, flyaways!
@@bryantmaximilionalpha2840 I believe it's an app issue. UAV said there are 12 satellites but the app shows none. After being closed and reopened, it showed full strength. I've seen this many times.
@@yquy I've still got more tests to perform, so I'll find all the kinks in it's armor and hopefully, get 'em all worked out. Sent the maker of the app a couple of emails requesting that they make some updating software changes to it, but haven't heard back from them, yet. May just open up the app in VB and make my own changes to it
Thank you, good.
nice
@Dare Master...I've been thinking the same thing, that maybe something within the motor housing has
(a) come loose
(b) broken winding
(c)metallic piece of debris gotten inside.
I'll first start by using my air compressor and blowing out each motor housing and then, go from there.
what antenna did u use for inside the drone to strengthen the video signal?
Links are in the description
i never got any toilet bowling issues with this drone but i do have video signal freezing anywhere from 100 meters out up to 300 meters and thats the farthest ive been able to make it without losing the video so im def gonna mod this one...i also just got the jjrc x17 and that thing toilet bowls like crazy every flight to the point that im gonna send it back for refund unless it can be fixed with an upgrade
What makes these birds toilet bowl, is the loss of GPS signals. Just like back in the days when flying your very first, cheap rc helicopter, without a gyro in it... YOU, had to be it's gyro and make it fly level and straight...same thing with the GPS module...no sat reception, no straight and level flying.
Locate where the GPS module is situated at in the body of the craft and then cut a wide opening in the plastic above it and tape/glue a thin piece of plastic over the opening. You should see a big improvement, afterwards. And always give the GPS at least 60 seconds to find enough good signal sources, before lift off.
@@bryantmaximilionalpha2840 thanks for the input,im gonna try getting a refund and if they dont then ill go ahead and mod the shit out of it
@@bryantmaximilionalpha2840 im just uploading todays testing video now,should be up in a couple hours,i tested 3 quads against each other to see which one was best,x17 vs f4 vs f11
I had a toilet bowl happen to me the other day, today I made sure to do a full compass calibration away from anything metal and did it slowly, and had no problems at all today.
I'm also going to immediately land the F11 if I see that compass calibration error in the app, I ignored it and that probably didn't help with the toilet bowl.
bryant ciao, what about with time battery...really 25 minutes??? and transmission to smarthphone is good?? ciao bello
Haven't tested out how long it will fly with the stock battery and after Modding, transmission is solid
1 Battery lasted about 22 minutes in cold weather
Just out of curiousity, how do you come to the conclusion there is no sattelites in the sky?
Why you put antenna 5.8ghz 14dBi for remote controller??and antenna 2.4ghz 3dBi to your drone??i dont get it,please xplain😓😓..i also use Hubsan kit..sorry my grammar is bad🤭🤭
Controller f11 pro just use frequency 2.4ghz antenna i think..just drone have receiver board antenna and camera transmitter antenna ..i dont know which 1 antenna is 5.8ghz and 2.4ghz
For Hubsan kits..use 13dBi 5.8ghz antenna on controller bcoz Hubsan have monitor and the antenna for video receiver 5.8ghz..can we use antenna 5.8ghz and replace at 2.4ghz antenna for better improvement??sorry i dont know anything about antenna😓
We can boost the antenna signal,but we cannot change the frequency from transmitter..teach me if im wrong😅
@@deendeen9798 right now, I'm just in testing phase, with these antennas, but to answer your question: the 3dbi antenna has a much broader broadcasting pattern, than the 14dbi panel antenna which has a much further reach, than the 3dbi antenna, which is great for long distance flying...as long as you keep the panel antenna aimed in the correct direction of the craft. Just think of a donut for dipole antenna broadcast pattern and an egg for panel antenna broadcast pattern. I do intend to use my homebuilt yagi antenna on my controller in the future, but as of now, it's only testing time for me. As far as the drones 5.8ghz wifi broadcast, that's for the camera wifi, which has it's separate wifi card installed...it actually looks like the wifi card inside of any laptop and can probably be switched out with one as long as you know the correct power and ground pinouts on the laptop wifi card.
@@deendeen9798 the small onboard dipole antenna inside of the drone, is the 2.4ghz antenna, just like the one inside of the controller.
The green bar is your battery life indicator, not satellite strength... sat strength is shown next to the sat icon. if you cant see the icon dont fly, but close the app and then restart it. hope that helps.
Thanks, I realized that a day after posting it, but I did get the GPS strength bars indicator functioning but I had to do a bit of resoldering on the module board. Thanks again!
@@bryantmaximilionalpha2840 Glad I could help, happy flying..
Hey nice video.
Did you already done a maximum range test?
If you want, I can send you a modified SJ F PRO App with 3000m flight distance; by myself
I've been having arming issues, so I haven't been able to fly it again. I'd love it if you'd send me that modified Pro app! Thanks!
Would love to have that app too
@@bryantmaximilionalpha2840 did you ever received the modified app?
@@stefanroverts963 no, I didn't receive it. Doesn't matter though, because I'm not going to continue flying this thing. It's just too unreliable and glitchy and I don't want an unexpected flyaway on my hands.
@@bryantmaximilionalpha2840 I haven't flown very much with it yet, but I only have good experiences so far. only the camera does not remain horizontal. one time it drops to the left, and the other time to the right.
I would love to have the modified app, but after 1 month of no response i start to think there is no modified app.
So where's the testing bro. I haven't seen must distance being made
Mantap👍👍👍
Anyway you could put up a link again because the one that you put up is now expired or something like that thanks appreciate it so much
Que tipo de antena la instalaste? Que características tiene la antena?
Hey! reworking the antenna increases the connection or is it better to keep the original?
If you know how, get rid of the original internal dipole antenna and replace it with something better.
I can’t fly my drone it shows me waiting for GPS signal do you know why ? Do i need Memory Card to fly my drone?
Just to check - you said you don't believe in GPS whilst using GPS?
Ummm, you need to reread what I said about satellites
Where do you think Satellite TV and radio comes from? and Google Earth?

When you range test? How distance can be achieved using an antenna mode??
Good question...Not only is the modded antenna, mounted externally, but it's something other than the tiny dipole antenna that's mounted internally and therefore, is subjected to EMI, caused by the other internal electrical components and wiring, thus giving you a clearer signal source, that's unobstructed and you can change the what decibel antenna that you'd like to use
Do you have to calibrate compass a drone every time battery swap
It's the safest thing to do, if not, your drone may not find it's way back home, if you press 'return to home', because it wasn't calibrated prior to launch.
After mod.. It is not better at distance
Hi how far does it go? Regards
Will be doing future range testing, soon, but won't upload video's here any longer. If you wish to keep up with my progress, subscribe to me @ rumble.com/embed/vanimj/?pub=gtg33
Help
I can’t fly my drone it shows me waiting for GPS signal do you know why ? Do i need Memory Card to fly my drone?
There can be a number of reasons for that issue. If you've seen my other videos, then you'll see that I've drilled a series of 1/4" holes directly over top of the gps module, as well as added a extra layer of shielding inside beneath it, to cut back on the EMI that it's subjected to and that helped my issue. Also, they have the calibration board mounted to the bottom of the gps module, so I don't think that helps out any. I've since separated the calibration board from the gps module and place it flat and level, on the bottom inside of the drone.
