Taranis Q X7 LIPO battery upgrade 5000mAh
WARNING
Be extra careful when working with LIPO batteries.
I did some testing with one of the cells. I charged it fully and then dischrged it with 500mA load until is reached 3.0 volts. I got 2850mAh out of it. Safe limit is around 3.5V after that voltage drops really quickly.
X7 current consumption:
- 140mA idle in D16 mode
- 150mA with backlight on
- 160mA with backlight and Ms. Taranis speaking

How you know. The lenght and the width of the wing
@@muhammedomar424 you pick length and width yourself. Look up "aspect ratio". Long and narrow wing like in sailplanes will produce a lot of lift but will be slow on roll axis. Short and wide wing will be fast on roll axis but won't produce much lift and will need more speed to stay in the air, like sport plane.
hi antti .. my graduation project discussion will be tomorrow and i have a problem .. when i use 2 helical antennas the values of rssi never change .. i test the 2 helical and they work ..but when i use 2 omnidirectional the rssi values change ... i use RD945 diversity receiver and i can't find a solution .. I'd be grateful if you help me.
Hard to say without seing your project, but one dumm mistake i've done is mix sma and rp-sma connectors. If there is absolutely no signal from one antenna, that could be the case.
Why you stopped doing videos? Hope you are well.
I got 2 small biological drones, they have endless batteries, never stop buzzing and require 24/7 maintenance. The last project I did took 2 years to complete (3d modeling, printing, arduinos, rf-modules and writing code) Every time I had a couple of hours, it took 1 hour to remember what I was doing. I've noticed that some other rc guys on youtube have experienced same fate. So I'm doing well, just taking care of my little drones. Best wishes to you.
Hi Antti, this is a brilliant design. I got inspired by your video some years ago and built a similar setup using 2 diversity receivers. The Quanum RC 540R does the guidance job with two 16-turn helical antennas. I added a small SD-card reader/writer for data logging and could fit it into the Quanum as well. The 2nd receiver, placed about 10 inches besides the Quanum, is an FR632 with one identical 16-turn antenna, pointing exactly in between the two guidance antennas, and a 4-leaf antenna for close range reception. I didn't care for vertical guidance. My construction is quite heavy and therefore using a big servo. Both diversity receivers feed their best signal into an Eagle Eyes FPV Station by Eagle Tree and the station outputs the better image of the two receivers for viewing/recording. Obviously, this is for long range operations. Your software was of great help and a good starting point. I adapted and expanded it a lot, up to the memory limits of the arduino. This works like a charm. Good image on 5.8 GHz up to a distance of 15.1 km (9.4 miles). This was the battery range limit of my small styrofoam model aircraft. Using a running average for the RSSI signals gave me very precise antenna guidance even at very low signal strengths.
Wow sounds pretty serious and awesome :D Do you have videos of your setup? Also it would be interesting to check what you have done in the code, have you published it somewhere?
@@AnttiVainik I had a big thread about the project on a German speaking forum, which unfortunately was closed down, loosing all contents. But you can find an image of the tracker and my version of your Arduino software by going to the 'euroconnection' URL with the TLD (Top level domain) for Switzerland.
i need to see your work thats good
I have been looking at this idea very closely and its very good. Do you have a schematic that shows the analogue circuitry for the RSSI? It appears as if the RC540r uses a receiver very similar to the common RX5808 found in a lot of FPV receivers but the one in the RC540r is slightly different, maybe a custom module? I would like to see the circuit and see if it can be used with the RX5808 receiver module. Can you help?
How to take the signal from this system and put it in the Goggles ?
I dont understand with FPV taking off the way it has why more less expensive trackers have not been released. I dont have $500 plus to shell out for any of the premade trackers out not to mention I'm wanting one that I can use for both Analog and HDZero tracking. If anyone had run across any resources please feel free to share....
yeah I feel the same. The sentinel antenna tracker from virtual pilot somehow puts your GPS coordinates to your vtx video so it doesn't need any additional stuff on your model which I like, although I didn't get how it should be set up since it's not natively supported by betaflight, but it's also too expensive at about £90 and you need a 3d printer to make it which I don't have.
@@flat-earther The Sentinel AAT can also be setup to track drones without a gps unit by tracking the telemetry channel of a CRSF RX. It can also do both analog and hdzero so yeah it's the one I went with..
@@battano oksy. when you said _track drones without a gps unit_ do you mean the drone does not have a gps unit?
@@flat-earther correct the Sentinel AAT kit can be configured to track the telemetry channel of a crsf rx so no gps units needed but can be configured for gps tracking as well
@@flat-earther I should add that the faster proximity no gps tracking setup does require the FC firmware to also be modified as it hides the tracking/telemetry data in the OSD of Betaflight/Inav/Ardupilot/Kiss GUI which is what the AAT decodes for positioning. The setup is really no big deal as the user community for the tracker has ballooned and there is even a gethub of latest firmware for damn near all major makes of FC's. Personally I'm still in the assembly stages with mine as I'm making mine with a swappable top to quickly go from analog to hdzero and am even ingratiating an Insta360 go mount into the antenna array so I can have FPV and LOS recordings of my flights.

good data, thanks
What is the airfoil you have used?
Awesome project,,can you make video on how you program the arduino,i need full details,,make video on full tutorial,i see this video but its not complete,can you please make video to how program the arduino? Thanks for making the video
How can I put the code on the arduino board? It always indicates a wrong translation to me!
My 2 meters flying with swept angle 22 degrees, is my swept angle too small? Never fly before still building the remote control.
Many people on the internet say 25 degrees is "optimal" (for what purpose I don't know) Also aerodynamicists say, swept wing are good only for flying really fast (transonic). High sweep angle moves CG back, which in some cases helps to balance the wing. With 22 degree angle you will probably have to put as much weight in front as possible. My guess is, lower angle wing will be more efficient, but higher angle wing, will definitely look faster and cooler :)
I started flying hang gliders in 1973. Also got involved with remote control gliders as well. Then I really got interested in learning more about the aerodynamics of hang gliders. in 1973 they were fairly primitive. I turned to paper to see if I could improve on the Rogallo design. It did not take me but a year to create a flying wing made of paper and Scotch Tape. It did not look anything like the Rogallo of the early 1970's but more like the modern hang gliders of today. The video I present is showing a quick build of the "OmniWing" and a flight off of Mount Nebo, in Arkansas. It is a surprising flight and I am so glad that my wife caught it on video. Enjoy! ruclips.net/video/SrZ1bqU_g4o/видео.html
So, how do you find the RRSI pin in the RECEIVER module? how did u know it was the 4th pin?
Hi sir, can get root airfoil you used for this?? called phoenix?? plz mail me that foil at somprasad0965@gmail.com.......i need to learn xflr 5....plz help me..
how this stability can be achieved?
what other resiver use this discontinued
Amazing work and video. I noticed that you din't improve design too much and you got a max L/D of 19, even if the wing aspect ratio is so great. Maybe you needed to do a type 2 analysis because it’s more of a glider than an airplane? However your plane flies perfectly. For me your video is a great inspiration along with sites like aerodesign de (use google translator). I have a comfortable big flying field near my home on a very large and shallow slope. The problem is that I can't fooly microsloping on that shallow slope with the current electric glider volantex ASW 28 unless a steady 10+ m/s wind is blowing because that glider doesn't have good enough L/D 12:1 at best and has excessive wing loading 45g/dm2. So I decided that I needed a super efficient rc glider with wing loading and L/D something like F5J gliders but 10-20 times cheaper :) I am now designing in XFLR5 my custom flying wing RC glider few verssion at once actualy 2-2.2m, 60-70dm2, mass 0.8-2.5kg depends on setup and/or ballast, aspect ratio including wingtips 9.5 only! I also created my own custom airfoil because all 2D airfoil that have high L/D just don't work in the 3D wing and even in simulation. The only thing that worked is the reduction in resistance, which is incompatible with a large camber airfoil. Using type 2 anlysis I got L/D 23-27 depend on wing loading when the optimal gliding speed is as low as 7-8m/s up to 11m/s, wing loading 15-36g/dm2. My custom airfoil is 8.5% (thinner or thicker has higher resistance and poorer L/D) has a relatively small camber, 1.34%, cm = ~ 0 at cl0, max cl 1.05 at Re 160k. I use some wing twist 2 degree. My airfoil a bit similar to the MH 64 but has more reflex and cleaner bottom. What I did was just a little decrease in Cd and a little increase in max Cl + some reflex compared to MH 64. I got those results after trillions of modifications :) I will build my flying wing in the spring or summer. If the design and airfoil will work well in the real world I will post the airfoil dat file and will make some video. Sorry for my english I use much help from google translater.
Sounds like you are really into this stuff, that is cool. I wish I had time to do RC planes and experiment with different designs. When you get your wing flying, send me a link to the video. It is always an inspiration to watch DIY planes fly.
Even if i follow all your steps with the exact same values, there are no opPoints in the stability analysis stored...
this is a very nice mod. I have the Quanum V2 Pro Goggles vor visitors. i will try this to build :-)
aaaaa i love the background music
Thanks for putting this YT video together, I have built one and it works pretty good
These tracker work with another receiver? Like RC832?
I have a Boscam RX-LCD5800 diversity video receiver, it has very similar electronic components to yours, almost identical actually. Do you think the rssi solder pad is the same pin as yours? Is there any way I could know?
Many receivers use same/similar receiver modules. Open your receiver and see if there's a module inside. You can then do a google image search "5.8ghz receiver module". There are plenty of images that show the RSSI pin.
@@AnttiVainik ok I've got my rssi pins covered, but I can't flash the Arduino for the life of me. I'm not sure what I'm doing wrong. "An error occurred while uploading the sketch" any help will be much appreciated. The RUclips videos are not very helpful. Edit: Arduino flashed with timer.h Last question, what's powering the Arduino during use? The regulator out arduino and servo power are soldered together at the board?
Could you kindly add TILT function in the code?
Awesome. Could you please advise me how did you find out RSSI_MIN and RSSI_MAX values in the arduino code?
Following... My servo keeps on turning, my RSSI_MIN is 120 & MAX is 400. I tried different values from 0-50, 60-200 etc. but still the same... I am using RD945 diversity receiver.

I'm new to fpv. Wow. Nice. I was also thinking about making a diverity 5 helix antenna . This can be my backup :) Great work.
how did you manage to turn on the radio with a single quick click on power button ?
I modified the source code, and reduced the power off delay to 1 second or so. Then recompiled the firmware and flash it on Taranis. I know it sound complicated, but its not. I just changed one number in the source code :)
Sorry I misread your comment. You wrote ON not OFF. Ugh, I can't remember, maybe I modified that too, or maybe the on delay has changed in newer versions. What version is your OpenTX?
@@AnttiVainik the turn off delay dont mind me, even if it could be a bit shorter (it's a nice security to not turn off the radio by error) But the turn on action could be really quicker I read somewhere that guys patched the firmware If it's the only way, i'll look at that :) I'm on openTX 2.3.5 thanks for your reply :)
Can this be done with a non diversity rx?
I want to track drone which can be 200 km away from me. Is it Possible to do this using RC540R diversity video receiver. Thanks
Absolutely NOT. This tracker is relative, it does not know where your drone is. If tracker looses lock, it may not recover. I't's only good for proximity flying.
Thank you for the demo, I have a couple of these motors and you answered all my questions.
Hello 8s this plane a good buy. 😀👌
It, reminds me of that Hangglider: ruclips.net/video/zWAka-xzjCY/видео.html ruclips.net/video/EIFaYRRhhG0/видео.html ;-)
hello antti, my tracker position is reversing, it should be left and right, but my drone moves to the left to the right tracker and vice versa. how to solve that problem ...
In the source code there is #define SERVO_DIRECTION 1, just change it to -1. It will reverse servo direction, simple as that.
If you are too lazy to modify the source code, you can just bend the antennas pointing inwards (cross eyed) or flip the receiver upside down, this should have same effect.
amazing...thank you antti ... it worked. Good luck. I'm waiting for the next video
@@AnttiVainik RSSI_OFFSET_RIGHT and RSSI_OFFSET_LEFT , filled with what number.....
If the tracker doesn't have constant offset in either direction, you can ignore this value.
And the power and ground leads from the servos connect to the power and ground on the Arduino?
Did you ever get the answer to this question?
I am new to electronics but I assume the 5v regulator connects to the power and ground on the Arduino?
Hi well done awesome project, have you made any updates to the Arduino code or is their just this one the original one? It works really good I found if it looses me, it struggles to search/find me again, in the code is it suppose to search left to right if the signal is lost to search for the signal again? Is it possible to add that in Thankyou
Killer video! Taking notes, thxs!!
On what have you based your Ranold's numbers?
Many years have passed, but.. My goal was to make a slow flying wing, so the Reynolds number was based on speed 30-50km/h and chord length of about 20cm.
