I still think this is for the tinkering RCer, not the racing or bashing type.
Sure, it's great for tinkering, but that's not needed. It's pretty much ready to go right out of the box. For a vehicle with only two channels, you really only need to set your steering endpoints. Sure, that's SLIGHTLY more complicated but only because the terminology is different, but that's like a few minutes of confusion one time. And even binding is dead simple and flexible because all it takes is to log-in to the receiver to enter your binding phrase. Done. (it supports the old-fashion way of binding too)
And I would argue it
is for racing or bashing. Racing because ExpressLRS is insanely low-latency and the radio is so configurable, it can do anything the top radios can do -- and so much more. It's great for bashing too. It allows you to run so many of your vehicles -- especially the older ones. I'm now able to run a 2S LiPo pack on my MT4 FT even though the Novak GTB ESC doesn't have a low voltage cut-off feature because the receiver included with the MT12 has telemetry and could read the battery voltage. Just a few seconds to add the parameter in the telemetry screen and I have a live read-out of my pack voltage. A few minutes of programming a logical switch and now I have an audible and tactile (vibration) warning along with a voice call-out of the voltage when the pack reaches the threshold. A few more minutes of setting up a drive mode and now in low voltage mode, it can automatically limit my throttle to just 20%.
I was also able to set-up an "arm" switch, so I don't get accidental throttle runaways when powering up vehicles. Holding the switch at the back of the base for >1 second will "arm" and "unarm" the throttle.
Now I'm finally getting around to picking-up LUA and starting to make some pretty custom telemetry screens.
I also have plans for projects to get GPS, ground-speed, rpm, & battery current telemetry -- just for fun. And maybe even design my own receiver with all the features I want. All this is possible because the hardware and the software is all open source. And it's glorious!
Oh, and it allows you to "loan" your models out... so if you have friends or just a fleet of vehicles and a few ExpressLRS radios that you share among your kids, you can connect to your model and enable "loan" mode and the receiver will instantly go into bind mode allowing your buddy to bind their radio temporarily and "return" it after they are done... Great for bashing with buddies.
And I've only just started to play with this radio like 3 weeks ago. So much more I haven't explored yet. And when Companion finally adds MT12 support, I'm going to be able to work much quicker.

My quote is always "why change if something works?" As in this topic I do see it with other transmitters as well. Beside people spend too much time doing an upgrade not reading the manual correctly like the limitation of the SDcard memory but also the small chance the update goes wrong and does not power on and here in this topic people facing errors in the new software.
Not sure I fully understand you. What limitation of the SD Card? Update can't really go that wrong. Hardware-wise, the Radios are just Arduinos. You really can't brick them. And backing up your settings is as easy as plugging it into the computer and dragging and dropping the entire SD card contents to your computer (I use a NAS that is backed-up nightly offsite).

I am way oversimplifying things here and there are other factors like reflected signals to take into account.
For anyone that still listens to the radio in their car, this is the same phenomenon that causes station to drop out and come.back when you roll forward a few inches. Yes I'm that old, and I still play with toy cars.
Yeah, I don't think that's not how things work.. The radio is emitting electromagnetic waves. Those waves propagate through space. They are not confined in a way that would cause reflections that generate standing waves with nodes that would cause a signal drop.. And if somehow that's true, then you'd have the same problem with ANY radio system. Most modern ones have the same 2.4GHz fundamental frequency and would have the same distance between nodes in a standing wave situation.
