With the ESP32 there's no problem supporting any protocol, but for now I focus on just having it ready with the basic features.

Understood, thanks.

Agree. In the longer term it would be awesome to have the mav2passthrough code integrated. At present, to use this with ULRS it's a fairly simple setup with only the ULRS Tx and esp32 board in a box at the back of the Taranis, but would be even cooler to have this all on one esp32 board.
You can see this box has been used for many different configurations over the last few years. I think I have the ultimate telemetry solution now though in combo with ULRS dolphin board in this setup. I am really hoping Flipflap will consider the integration in the longer term rather than reinventing the telemetry wheel.

Hi Paul,

Nice and neat enclosure you have for your setup. I'm still using my original external setup which surprisingly still works since I am careful with it. If I ever upgrade it, I would like to use my Horus X10 display without the extra boards. Note that I don't use that antenna for flying.

Having the ESP32 board integrated would be a good start!

Cheers!

But I think the FC shouldn't react in this way and set full throttle when the plane has landed. I don't remember having seen Arduplane doing that for example, so maybe there's also a setting to check on INav.
I was out flying this morning and had a recurrence of my FS event after landing. On this occasion, my OSD RSSI was reporting 64% after landing and then, the OSD reported "RX! RC LINK LOST" for a couple of frames just prior to going into FS. In my first FS experience, I was confused because I was looking at the OSD RSSI reading which remains steady at 53% throughout but have learnt that this is normal iNav FS behaviour when the RX RC link is lost.

So, onto the bench for more testing.
I reduced my signal by using a HK 100mW TX instead of the usual 1W TX and put 13 db of attenuation on it and placed it in another room. Managed to get the RSSI down to 43%. I then bent the lower element of my ULRS dipole (see attached images) to see if that would trigger FS and it wouldn't. In fact, my RSSI only reduces by about 3% with a bent lower element. I then moistened the underside of my wing, dipole and Mini Bee cover ( just covered with gaffa tape) and then bent the lower half of my dipole in much the same way as the plane does as it lands on wet dewy grass. Still didn't go into FS though. I also lowered the wing whilst bending the lower dipole element to simulate the plane rolling onto it after landing and still didn't go into FS.

In the conditions this morning, I'm pointing a 1W signal with a slightly directional antenna (Moxon) and getting 65% RSSI on wet ground about 50 Metres from the TX.

So, none of that explains how I'm triggering FS in iNav. Here's the iNav FS link. I don't have an Aux mode FS setup. The only thing I'm sure of at this point is that iNav thinks the RC link is lost. I haven't been doing any black-box testing, so I'm going to have to start recording onto an onboard memory card and see if I can decipher more detail as to why the link is being lost. It doesn't seem to be related to signal strength IMHO.

It's quite disconcerting to have your plane fire up after landing.

Does anyone know of a good source of ultimateLRS compatible receivers? Ideally without having to build one from scratch and source all the components separately. Does anyone sell them?

Yes, have a look at the OrangeRX modules : http://www.itluxembourg.lu/site/mate...to-fly_modules

I got a question about the orange 1W Rx modules. As 433 MHz Rx modules are not available , Can 915MHz modules be made to work on 433 by changing antenna and firmware? Or the internal circuitry is totally different? Thanks.

They are completely different modules, the IC itself is the same but all the other components are specifically tuned for one frequency band.

I can only find the transmitter modules in stock in 433mhz and they are too large for my small hexacopter.

Then you can try the Wolfbox combo here

The smaller module is only 100mW but it should be fine for a copter.
