Hi Guys,

I cant really find out if the components that I want to buy will work together well.

I already bought
I'm about to buy
But now I have doubts if the RX-Protocol between RX and FC will work reasonably.
I will fly without goggles and therefore need telemetry on the remote-display.

Hope someone can give me advise here!

Think it should be fine you can dig up the exact FC model and search for receiver model and probably find someone using both but for the most part the receivers and FCs will work fine together. There have been a couple of exceptions where the signal is inverted (highs are 0 instead of 1 or vice versa)

Looks like Oscar has a real comprehensive write up here on how to handle it if the signal is inverted:

Uninverted SBUS and Smart Port on Frsky Receivers - Oscar Liang

In this guide I will show you where to get the uninverted SBUS and Smart Port signals on many different Frsky receivers, including the R-XSR, XSR, X4R-SB and XM.
oscarliang.com oscarliang.com

He also mentions F1 and F4 processors suffer from this problem because they don't have built in ability to flip inversion of a pin via chip configuration/software changes so requires using a different physical connection in most cases it looks like if using F1 or F4 (actually kinda surprised I've never run into this but I do usually fly spektrum and have limited experience with the wide array of receivers available). Says the F3 and F7 based FCs could handle this with config change.

You will have a very difficult time trying to fly the tyro 79 without goggles as it's meant for fpv.

Hi Dugdog47,
I'm aware that LOS flying is considerably harder than FPV. But I still prefer that (the graphics are so much better ;)).
And I have some LOS experience with the MJX Bugs 3 mini.
