Folks. Just started flying a new iFlight Chimera 7 Pro with a RadioMaster TX16S Max and a TBS External Crossfire module set to 1 Watt max and in dynamic mode. I keep hearing about the huge long range of this system. But as soon as I get just at .9 miles away the TX symbol in my DJI goggles start flashing red and I'm down to 2 bars.

So I immediately turn around and come back. I do not understand why I'm getting this Red Flashing warning at such a short range.

Am I just being to cautious. Can I keep flying? The goggles have a range of 2.5 miles so I don't understand why the TX signal is limiting me so much.

Any insight to this would be helpfull.


I have set up and tested the GPS failsafe and it works great, so I know at least I'm safe if I really do get a signal drop off.

Mike.

What is the best way to mount LED lights to the carbon fiber frame? I was thinking superglue, so it would be lighter than double sided tape? What do you guys use? Thanks!

Hi everyone,

I am new to quads and have bought a BnF drone - Babyhawk II HD - which I try to fly with a Jumper T-Pro (4-in-1) with external crossfire Nano Tx module. This drone works with DJI goggles which bound to the drone fine and I updated the firmware as suggested by the DJI Assistant software at that time. The nano tx module connects OK to the Jumper and is being shown in the internal radio controller's menu. It also has its lights at the back changing their color to yellow and green when modes are changed. It has also been updated to the latest version available on TSB Agent X. The internal mode on the Jumper has been set to off with only the external - CRSF - activated.

I am unsure what I am doing wrong but the drone could not be bound to the radio controller. I go into Crossfire Configure menu where I see all relevant settings, choose Bind, the radio goes into Binding mode, the module at the back starts flashing green, I press the drone's bind button but its stays red no matter how much time passes. I have watched some videos where it seems that when a USB cable is inserted into the drone's flight controller its receiver is being shown in TBS Agent X but this didn't work in my case. Betaflight however connects to the drone doing the same and it shows Crossfire as transmission protocol there with no changes made (I initially thought I have been sent a drone with different connection protocol by mistake).

Could the binding issue be related to the fact that the rx and the tx firmware versions are different? if so, how do I make them to have the same version, especially on the receiver at the drone? A thing I also noticed is that when I deactivated the internal module and switched to CRSF (external), the default 250Hz goes down to 145Hz irrespective to the regional frequency chosen, i.e. 868, 915MHz etc, or other settings.

I apologise in advance for the very basic questions, however I am indeed lacking the skills to make this work as this is my very first drone and all information and videos I could find relate to either different radios, drones or problems. TBS CRSF and Emax manuals are the same.

Many thanks in advance for any advice.

Hi everyone, 

I am building  an about 5 inch drone with XING-E Pro 2207 1800KV 3-6S motors.


The weight less than FC and less than propellers and fpv system is around 260 g.

I prefer more minutes of flight at the expense of weight and greater reactivity.




Which 6S LIPO or Li-ion battery do you recommend for 8-10 mins flight time? I would be grateful if you give me more alternatives.

Thanks for the availability.

Hello, 

I have 2 x Duracell Rechargeable AA 2500mAh NiMH batteries and had been charging them using dedicated NiMH charger.
Recently that broke.

I have a ToolKit M7 charger, which has NiMH mode and want to see if I can use that to charge these batteries. I will use 2 x 1.5V AA battery holder two put the batteries.

Do I simply have to connect the red and black wire of holder to Toolkit M7's output and charge?
And the charge settings of NiMH mode shows, 
Cells - Auto (I can set cell count manually too)
Nixx Peak - 5mV (I can lower or increase this)
Carge Current - 3.8A (I can lower or increase this)

Is this good?

Thanks.

Today I decided to switch one of my quads back to analog, so I can have others wear my spare set of goggles, and get the same view I have - I was originally running a Vista unit, and had full OSD, but as soon as I wired the cam and VTX in and set up the VTX table, I have no OSD at all - I have tried the 'usual suspects' (Switching to PAL / NTSC, reloading fonts, checking all wiring, correct UART selected), and still have no OSD - I have included a pic of the wiring for the VTX, plus my 'diff all' and 'dump' - Hopefully someone can figure out what my issue is!

I also tried two other working VTXs, and same result, no OSD ...

Dear all
hope you are all well. I have a Beta95x v3 HD, it sank in a pool, hah, anyway. i changed the FC(AIO), Caddx works well, when i connect it to betaflight, on receiver tab channels didn't work, i thought my crossfire might damage, today i changed the crossfire, and unfortunately, the problem still stands. i use the same model on my tx16s, LED color is green on crossfire. mixer and ... are same( because i use the same model on controller). 

i checked the resources and ... everything seems same, i upgrade my module(on tx16s) and update crossfire to the latest version, and nothing happend. 

would you guys please help me? 
you can find my DUMP and screenshots of my betaflight setting( just filters might updated since this version of dump) here: https://drive.google.com/drive/folders/1...sp=sharing

please help me with this issue.

best

Flying ELRS until a crash “damaged” rx2…..Was going to remap the SBUS pad to rx2, but noticed it already has the same resource value of A03. I’m now wired to TX2 and “RT2|”(SBUS -see image). FC won’t bind to rx in ELRS configurator. Is there some sort of remapping that needs to take place? Do I keep the CRSF protocol?

Hello All;

I hope someone here can help me with this rather bizarre issue.
I've set up a Bee Brain V2 without too many glitches but this is way beyond me..



I started with a default set up and;
SPI Rx + FRSKY_D
TAER1234 to match my Rx config

It appears to binding correctly and connected but with no response from the drone to ARM or THR, so no motor activity..
While still connected to Betaflight I get these rather odd waveforms in response to the Tx.

Any clarity would be greatly appreciated given the total lack of support information on the product..
