Impressive! And at such a reasonable price, too. My HapptModel ES24TX Pro has served me well for 2 years, but it needs a new antenna, which was set to cost me a quarter of the cost of a whole new module. I've been drooling over the Radiomaster modules for some time, and the chance to get a good brand dual band gemini module for cheap was the final straw. I have slapped the money down and ordered one direct from RadioMaster, complete set of module + xrossband receiver + all the antennas. Now I just need a quad to put it in!! I love that this will just keep working with my existing quads while giving me a no-risk route to experiment with 900 MHz and Gemini. Bravo, ExpressLRS team and RadioMaster, you are just hitting the ball out of the park.

Always thought that "Dual Band ELSR" (900/2.4) will work in a way that for example: You will set a 1000Hz rate, and 1000 packages will be transmitted over 2.4 (with benefits of latency), and every 10 packages, a package will be sent through 900Mhz. That is why You will get a speed of 2.4 and 'failsafe communication' over 900.

I fly 900mhz almost exclusively with my FPV gear and had two instances of close-range (about 200m clear line of sight) failsafe due to what I assume was a nearby high power aggressor. RTH worked, so no biggie, but I'm pretty sure X band ELRS or FrSky Tandem would have prevented the link loss. I can see how the majority of current 900mhz pilots transition to this.
