11
+
12
+Due to a combination of various reasons I haven't actually been doing any [FPV flying](quadcopters.html) for the past five years or so.
13
+
14
+This had to change!
15
+
16
+## Taranis Firmware
17
+
18
+My [Taranis X9D+](https://www.frsky-rc.com/product/taranis-x9d-plus-2/) has been running [OpenTX 2.2](https://www.open-tx.org/) up to now.
19
+But there's a new fork around, called [EdgeTX](http://edgetx.org/).
20
+From a user perspective it's basically the same.
21
+It is useful for potential future use of [ExpressLRS](https://www.expresslrs.org/).
22
+
23
+So I upgraded my transmitter.
24
+This brought some headaches, as it turned out because I was trying to flash with a faulty USB port on my PC.
25
+Fortunately even with a completely erased flash the STM32 bootloader is still available via USB, so you can always revive a bricked Taranis without special hardware.
26
+
27
+<!--%
28
+lightgallery([
29
+    [ "img/2023_05_13_fpv_1.jpg", "Taranis X9D+ opened" ],
30
+    [ "img/2023_05_13_fpv_2.jpg", "Closer look at Taranis X9D+ RTC battery" ],
31
+])
32
+%-->
33
+
34
+They also added a check for the voltage of the RTC battery, which promptly informed me that it is empty after upgrading the firmware.
35
+Luckily I still had a spare CR1220 watch battery in a drawer, so I just replaced it.
36
+
37
+The MicroSD card was also broken, so I had to prepare a fresh one with the usual [LUA scripts](https://github.com/betaflight/betaflight-tx-lua-scripts) and the [Mia Winter voice pack](https://miawinther.bandcamp.com/album/mia-taranis-voicepack).
38
+
39
+## New Copter Batteries
40
+
41
+The one thing that was really totally unsalvagable after the five year break was the batteries.
42
+Most had at least one cell completely dead.
43
+I actually tried flying with one of the remaining batteries.
44
+The copter did take off but the voltage immediately sagged to unhealthy levels.
45
+
46
+So I got three [Bonka U2 Series 4S 1400mAh 130C](https://www.mylipo.de/Bonka-Lipo-Akku1400mAh-148V-130C-260C-FPV-XT60) LiPos.
47
+Quite pricey but they work fine.
48
+
49
+With these I could take my [LX5](lx5.html) out to fly properly again.
50
+
51

55
+])
56
+%-->
57
+
58
+The copter still pretty much worked fine.
59
+It had some configuration issues, so Smartaudio and the Telemetry UART did not work, but this was already the case when I built it in 2017.
60
+
61
+## Upgrading Betaflight
62
+
63
+Of course I also had to upgrade Betaflight.
64
+I was still running version 3.5.0 from 2018.
65
+The current version is 4.4.1 which comes with a whole bunch of improvements.
66
+
67
+I also took this opportunity to finally put all my old and current [Betaflight config dumps in a Git repo](https://git.xythobuz.de/thomas/copter-configs).
68
+
69
+Some slight fixes to the hardware were also needed.
70
+One of the metal stand offs has already sheared, I had to cut a slot into the small remaining thread to get it out.
71
+
72
+<!--%

76
+    [ "img/2023_05_13_fpv_4.jpg", "Metal stand-off with slot cut into thread" ],
77
+])
78
+%-->
79
+
80
+I also noticed that the UARTs for Smartaudio and Telemetry were simply swapped in the config.
81
+After fixing this they both seem to work fine.
82
+
83
+## Spectator Monitor
84
+
85
+One recurring problem was the power switch of my spectator monitor accidentally getting switched on when putting it back into my backpack.
86
+So I replaced the switch and added an improvised "roll bar" to avoid this issue.
87
+
88
+<!--%

+    [ "img/2023_05_13_fpv_12.jpg", "Power switch on spectator monitor" ],

92
+    [ "img/2023_05_13_fpv_6.jpg", "Look inside the spectator monitor (no flash)" ],
93
+])
94
+%-->
95
+
96
+While doing this I also noticed that there is also an Arduino in there.
97
+It is used to automatically switch the FPV Receiver on after powering on the whole device.
98
+Unfortunately I can't find the source code, but it is simply toggling a GPIO after some time, so nothing too difficult.
99
+
100
+## More Flying
101
+
102
+So with the tweaks to my transmitter and copter done I headed off to try it out again.
103
+

108
+])
109
+%-->
110
+
111
+This flight was cut short a little by a local resident.
112
+They informed me that I shouldn't fly there to not interfere with local wildlife.
113
+I was not up to arguing, so I left after only two out of three batteries, or in other words eight instead of twelve minutes of flight time.
114
+I also didn't want to stress the point that this was next to a local small-scale airport, where propeller airplanes like Cessnas regularly take off and land (but not in use on this day).
115
+So I don't think my twelve minutes would have done much harm, relatively speaking.
116
+
117
+What can you do?
118
+At least they were nice about it.
119
+🤷
120
+
121
+## Cat Content
122
+
123
+Also I kinda lost possession of [my FPV backpack](https://www.lowepro.com/global/quadguard-bp-x3-lp37090-pww/).
124
+The cats just have to occupy any available surface.
125
+There seems to be no way around it.

133

134
+But that's ok.
135
+It's just all the hair that's a bit annoying...
