Going to buy a new radio, but I want to be sure about some features

Hi all,
I need to take apart my old 35Mhz radio and switch to modern one to fly with both old style RC planes and do advanced experiments with Arduplane.

After some research, I’m oriented to buy something with the ExpressLRS system, with

I found interesting the following products:

My question is: Can I accomplish all the functionalities I wrote above with both?
Do you have any other advice for transmitters with similar features?

Thanks!

Unfortunately right now you can either have GCS telemetry or Yaapu’s telemetry not both though generating Yaapu’s custom telemetry on TX is being worked on. It is a limitation of ELRS and Yaapu’s script.

I will just add that the Radiomaster TX16S is a great radio regardless of the feature set you end up with.

I see. So I can’t have both at the same time. It’s not a too bad thing however.

I’m seeing now that Jumper T15 seems not based on openTX, so I think it can’t even run Yaapu script. Is it correct?

OpenTx is old news, it’s all EdgeTx now. And, that Jumper Radio is supported but I would go with Radiomaster anyway.

Thanks both,
I live in Italy, so I can go only with 2.4GHz.
I definitely need the 6 switches. I already did too many tricks to change flight mode with my old 35Mhz Graupner MX12

I just read the Jumper-t16 manual and also that one runs EdgeTX.

@dkemxr why you would recommend the Radiomaster T16s? You just love it or you see weakness with the Jumper T15?

I do love it and I admit to not have personal experience with Jumper. Based on posts on the forum here I would say Radiomaster is a favorite but that’s just anecdotal.

I for sure like EdgeTx, and OpenTx before that on a Frsky radio, so perhaps it’s personal preference after that. I came from Spectrum and was very happy when the last of that was replaced!

You can only use WIFI with internal ELRS modules which typically causes issues with MS Windows 10.
The USB on the radio does not connect to the ELRS module’s telemetry because the radio does not know the mavlink protocol, only crossfire.

I read of people fighting with Microsoft Defender to get data through the backpack.
The unavailability of usb connection with internal ELRF module is written also on the ExpressLRS Mavlink webpage. I was aware of it.
So, at the end I’ll try to use the wifi, if doesn’t work I’ll then switch to an external module and use the usb cable…
If it doesn’t work again I’ll switch back to the old two transceivers method

Thanks again

Finally bought the Radiomaster Tx16s mark-II with two receivers:

Tx 16s is a good radio .
尽量不要在遥控器上运行Yaapu或者其他的程序。
用WIFI背包链接电脑后，用MissionPlanner来处理参数和接收飞行动态。
如果用遥控器来处理会影响很多事情，例如回传回来的GPS位置信息就会断断续续。
飞机上装了Ardupilot飞控 ，其实遥控器的很多功能不重要了，大部分当作一个飞机和电脑链接的设备而已。
基本上几架要飞的飞机只要在遥控器上设置一个模型就够了。
遥控器设置的差异可以没有，参数性能的调整都在MP里面处理。

I have an update.
Now I have got my radiomaster tx16s with an XR3 receiver.
Everything works perfectly, and also the ELRS Mavlink works perfectly just following the documentation.

I’m able to connect reliably to arduplane with Mission planner on my windows 11 pro PC to the tx16s backpack with no issue at all.
I tried also to use mission planner on an Android tablet and it works perfectly as well.

Yeah, the sad thing is that yaapu doesn’t work…
