The above video is really a blast, as someone said better than a spaceX rocket launch.

A detailed discussion of the comparison occurred on RC Groups: https://www.rcgroups.com/forums/showthread.php?4403131-Interesting-radio-comparison Some of the posts express outrage at the result, g...

Thanks to several posts on the PRCAC whatsapp, I now have seen an amazing comparison of major radio brands. This video is a big deal, given no comparison  of this quality has ever been posted, AFAIK. ...

I just realised there are 2 Matek product websites for the R24-P rxs with different recommendations on what firmware should be used: https://www.mateksys.com/?portfolio=elrs-r24-p (the one ...

On the product page Matek says you can use a firmware: ExpressLRS MATEK_2400_RX_PWM, in addition to the "Generic ESP 8285 " which is also referred to as DIY ESP 8285. I used R24-P PWM that I selected ...

Quite a few people use this rx. I thought I would try updating the firmware on one of my models which had elrs 3.0.1, even though it worked fine, given that the current firmware is now 3.3.2. I always...

If you fly with elrs at McCoy, you will find that problems of control glitches (/- crashes) do not occur, or at least the crashes are not caused by radio signal issues. So a major upgrade to standard ...

Its a really informative plot, and I like your RSNR method, RSNR=2*RSNR+20. Since 20 is a gridline, you can immediately see if RSNR drops to zero. Great work.

Some really good log plots here, including some zoom in. And I am impressed you are getting 9 minutes of flight time. I have not seen your plane nor heard about it, I wondered if I could tell anything...
