Radiomaster TX16S with Dragonlink, Yaapu, Mav2PT, Arduplane, and 26800 LiIon cells.

This is just a short demo video of the following working together:
TX16S
Dragonlink V3 transmitter and latest MicroRX using UEXP3 telemetry with flow-control enabled
Mav2PT firmware loaded on the Dragonlink's embedded ESP32
Yaapu telemetry LUA running on the TX16S for live on-screen telemetry

Hey! Just ordered mine a few days ago. Pretty exciting video thanks for the info.

[@Rednecklesson]

This is a great setup. I'd love to know more about the MAVLINK passthru.

[@JD_1]

Pretty Awesome!

Robbe Calima on your computer screen??? That glider is a good one.

Please make detailed video 🙏 My dragonlink Mavlink over Wi-Fi or USB is not working 😭 Followed their poor documentation to the letter.

[@bugsysiegals]

How did you assemble these batteries? Do you solder them, weld them, tape a connector between them, etc.?

[@Noircogi]

I soldered them. The space is very tight side to side, so I didn't use heat-shrink. I used hot-glue between the two cells, a normal 2S balance connector, nickel strip, and kapton tape over the ends for insulation, and down the middle for a bit more structural strength.

[@BDRCkid]

Hey Scott, Great video! do you have any documentation on how to load the Mav2PT firmware on the Dragon link? Edit: Never mind I found it in your doc for an external wifi set up. Thanks!

[@JHarris]

Wow Scott, this is fantastic. Thank you. I am working to do this myself and already have a pixhawk 4 on the way along with a radiomaster and am looking to get the dragon link. I know what the stats say about 433 vs 915 mhz, why do you like the 433 more? Simply for the longer range and better object penetration?

[@Noircogi]

I have both 433MHz and 915MHz Dragonlink systems. Since I fly in a hilly area, the 433 is much better due to its better penetration. It also works way better with 1.2GHz video.

Do you have setup guide of DL V3 with TX16S? Thank you

what settings do you need on dragonlink for full telemetry (accel and sensors)

What are your serial settings on Mission Planner and what baud rate are you using on dragonlink Tx and Rx?

Nice video Scott! Great job. What type of Rc transmitter connection cable did you select while purchasing Dragonlink V3? I have a Radiomaster Tx16s Mark II, so which cable connector would suit best for external module? Kindly advise.

[@Noircogi]

You just use the normal module bay connector. For this setup, you also connect the telemetry input pin.

Is dragonlink similar to crossfire? I am new to this stuff^^'

[@Noircogi]

Yes, Dragonlink is like a higher-end version of Crossfire with much longer range. It operates on the 433 MHz band and requires an amateur radio license to use.

[@checkm8606]

@@Noircogi oh that is interesting:D the license is for USA or where do you need it (Germany?)?

[@spyder000069]

@@Noircogi I would argue that crossfire is the higher end system. The onboard oled and controls let you configure it from the device and now you can also configure CF through opentx right on the radio. The DL you have to plug up to the PC. The software is much further advanced than DL. I find the response much quicker too and you can run 57k baud from the CF without flow control but DL you have to lower to 38. The esp32 on the DL is interesting but not really any more useful than the bluetooth connection the only difference is the CF bluetooth always works and the DL's latest bluetooth had all kinds of problems so the wifi is really a bandaid for that situation. The only thing DL has going for it is 433 which I have no idea why TBS hasn't put out CF in a 433 version because they would take over the market. I have been out to 28km with the CF so range is good. It actually outran my DL the other day that failsafed at 18km (both same setups, minitalon, moxon on tx). CF big downfall is it doesn't work with 1.3 video and 2.4 can be hit or miss with interference.

@@Noircogi will old version dragonlink works too?

[@Noircogi]

@@pelurusilver Yes. You can use an external ESP32. I've pre-built the code for it with instructions here: docs.google.com/document/d/1ePGAmYa-GSwJ9TrpRcMSZ5HjKpIELJfxtvpISxID2Xs/edit
