How to wire my VTX to FC

February 1, 2020, 10:45 am

I'm working on my first build so the wiring of all my parts are a little confusing to me. I have the Eachine tx805 5.8g 40ch VTX that I need to wire to the Mamba f405 mk2 Betaflight FC. As you can see in the pictures, the VTX wiring goes on the top right of the FC, but since this is a 12v VTX, I should not be wiring it to the 9v or the 5v pad, right? Where should I wire that then? 

I guess I just want some clarity as to where each wire should be soldered on the FC. Thanks in advance!

I did some estimates based on visuals in the footage (no gps yet sorry) and I think it was between 1.5 and 1.7 miles. 
Got pretty risky at times Smile

China has deployed an army of drones to disperse disinfectant over villages and cities in the latest attempt to combat the spread of coronavirus.

Footage posted to social media in the coastal provinces of Jilin, Shandong and Zhejiang shows drones hovering in the air as disinfectant liquid is sprayed from their underside.

Michael Rollins is hosting this live stream on Sunday 9th February at the times below. I guess this will probably involve some heavy discussion around Remote ID amongst other things, so probably worth a look-in (or watching as a catch-up later if you can't watch it live).

Hey guys and girls, this is my very first post inside any forum...., So here it goes. I have a new Betafpv 75 Pro 2, with a built-in FRYSKY Receiver. My Taranis Qx7 is from America and it's also brand new. I'm having a hard time finding any information on the binding procedure. Any help would be greatly appreciated. Thanks!

Help Me Decide: X9D vs T16

I am in the market for a full-size radio.  I like my Xlite Pro a lot.  But there are enough little things about it that make me want to try a full-size radio.  The last full-size radio I had was a Futaba 8FG which I used with Frsky compatible receivers.  I'd love to rock the 16SZ which is Crossfire compatible but way way too expensive and also I am too reliant on OpenTx.

I am leaning towards the X9D almost entirely because it is smaller than the T16.  Is that right?  Other than that, I'm not sure which one to go with.  I would have gone with the X9 Lite but if I go bigger radio, I will want a full-size JR module bay.

Mamba mk2 f405 tx1

Just a quick question. Sorry I'm new to the forum and search didn't bring anything up so I thought I'd ask.


I have the mamba mk2 f405 full size board. Looking near the sbus pad is a tx1 pad. Is this an inverted pad for smartport or inverted. Basically I am using the R9mm and am using fport. So not sure if I should solder the smartport wire on reciever to inverted or inverted signal. Wanting to keep uart 3 and uart 6 free for GPS and smartaudio.

I wish these vendors would make better manuals for the FC than just a diagram, that doesn't even list all the broken out pads

VTX / Camera Testing Rig

I got sick of adjusting my FPV cameras on my builds worrying about VTX heat on the bench and generally dealing with the tight space.  So I designed and printed this ghetto rig that holds a VTX, a small fan, a FPV camera, and a lipo.  I got a little fancy trying to make as many possible camera connectors I could along with their joystick controller adapters (why isn't there a standard?!).  But wow this makes it so much easier to take your time to properly focus the camera and adjust the settings.

[Image: gGKuEAb.jpg]

It's nothing fancy right now but if people want changes done to the rig design, I'll make those and post it on Thingiverse.

I plan to also use this rig to do antenna SWR testing since it can keep the vtx cool.

Twitching Quad

I've got a few weird things going on with my quad. I've been having lots of RXLost and my Nazgul5 is twitching a lot during flight. I've outlined some changes and things I've done recently below.

Video of twitching and RxLost. 



I think the best place to see the twitching is just after the 2:00 mark. There is a RXLost after that at about 3:00 that smashed the front of my quad, but only appears to have messed up the focus. I'll have to refocus once I get this figured out.

  1. Recently changed to a Jumper T16.
  2. Performed the T16 fine tune.
  3. Changed out antenna on R-XSR to these. 
  4. Also getting lots of low RSSI warnings on my Tinyhawk S with the Jumper and I also did the fine tune on that one as well.
Could all of this be bad connection from the Jumper? Incorrect antenna's? Something else?

Thanks,
king

TBS Crossfire

I am currently considering buying a TBS crossfire module. I have looked at all the options, but do not know what to choose. There is the regular module, the lite, and the micro. What are the exact differences between all of these? Also, which receiver is best to put into a 5 inch quad? 

I am planning to use an FrSky Taranis X9D.

Thanks.

VTX default power

Hello, I cant find any info for my specific VTX Tank Ultimate. How do I set the default output power to a higher setting? On power up it defaults to 25 mw on the osd in the goggles. I changed the vtx power setting to 4 in the CLI but it doesn't make a difference. 

Maybe the battery needs to be plugged in to make this setting stick? 

I have to do left yaw, pitch up and go into the menu every pack if I am flying a little bit further out. 


Or am I missing something...

Best way to keep Rx antennas away from props?

February 3, 2020, 4:54 pm

So the weather here in Chicago hasn't been favorable to flying, but yesterday was a nice temperature break so I took my Wizard on it's maiden voyage.

Wind was 15mph so I didn't get far (started with my Tinyhawk to be test the waters but it blew away) so I tested the Wizard in angle mode only, but I noticed when I punched the throttle I heard some "bad noises" for lack of a better description and lost control. While I rebounded successfully each time, I'm almost positive it's because my Rx antennas went down into the props during the quick ascent.

My first reaction was to shrinkwrap the antennae to the Pagoda antenna, although I have read the Rx antennae are supposed to be at a 90 degree angle from each other.

I'd like to keep the antennae clear from the props, and have read about everything from coffee stirrers to securing the antennae to the legs of the quad.

What way would you suggest?

Tinyhawk S 1S Low Thrust

My Tinyhawk S works great on 2S. When I but on a 1S battery it has trouble lifting off. One or two motors don’t spin up. When it does liftoff it flies ok until battery voltage decreases below 3.7v. Around 3.7v throttle position is getting high to stay in the air and rapidly reaches 100% and it can’t stay in the air. This happens after only 30sec to 1min of air time. The batteries are new. Is this normal for 1S on the Tinyhawk S? Shouldn’t I be able to fly down to 3.1v where the low battery alarm is set?

Hello again.
I made a camera change on my quad.
After powering it up, my quad does not respond to Taranis inputs plus it does not ARM or change any mode.
Mapping is correct.
However the R9mm green light is steady and I do have Telemetry info on my Taranis.



Frame :QQ190RTF
FC : Colibri Flight Control board
ESC : TBS 2 ESC boards
Motors : T-MOTORS F40 PRO III
FPV Cam : Caddx RAtel 
VTX : TBS TRIUMPH FPV antenna

Dual Camera RC Tank project

Howdy!

Spoiler alert: I have 0 experience with drones or with FPV camera's and goggles ;-) I do know a bit about electronics and soldering and stuff though.

Here's what I'm doing: I have a scale 1:16 Torro T-34/85 tank with BB system. My goal is to have a camera on the turret/barrel, and one in the hull (the tank has a driver's port which opens, where I would mount the hull camera). The idea is to have an FPV tank, with view from the driver ànd the gunner. The turret can turn 360 degrees, so this way I can drive in the main tank direction, and aim and shoot at another direction at the same time.

Also: I want audio, so I can hear the tank, and perhaps impacts on my tank from other BB tanks.
Also also: I want both camera systems to be stand-alone. I don't want them to depend on the tank's battery and electronics. (This is for ease of use, and to be able to apply the camera+mic systems on other tanks).


Now, I already have some cheap FPV camera + VTX (without audio support) and an Eachine EV800, which I'm now building and installing on the turret. I don't see any problems here, but it is a prototype, so who knows what will happen.. One challenge: the camera+VTX works on 5V, and I have no experience with LiPo batteries, nor do I want the tank to provide power. So, I'll build a detachable battery pack comprising 4 AAA 1.2V batteries, achieving 4.8v and 1000mAh. Not sure if it'll work, but we'll see!


Coming to my question: If the first camera prototype camera on the turret works, I'll start work on the second camera for the hull. I want this camera to transmit audio as well, though. I'll also need a second RX and screen.

When it comes to audio, I'm completely baffled though. I find many VTX's with "Smart Audio" and OSD's, BetaFlight and Lua and stuff like that, but this is a bit too complex for me. Obviously, this is also because that technology is aimed at drones, which I have no need for. I only want the VTX to also send audio, I don't need any other flight or battery data or statistics.

I find standalone Microphones for 2euros, using 12V power, so I could hook one of those up with a 12V battery. But, then I'm stuck with the transmission again. I can't figure out how to find out of a VTX also sends audio. I read somewhere that some VTX's have a space tagged with an "A", where you can solder the white wire from the standalone mic on, but I find no VTX's to buy which support that feature.

Long story, sorry bout that..

Long story short and summarizing: How do I build/buy an FPV cam with VTX and audio transmission, and which FPV goggles/screen can I use with that (more importantly, is it compatible with an Eachine EV800), without the use of Betaflight and programming stuff.

Thanks for bearing with me :-)

Do I set the rates in the radio or betaflight on the receiver and does one supercede the other?
