Thanks for another brilliant review, Whirly Bloke. I've been waiting for RadioMaster to produce this. I plan to upgrade my 7" quad to this system. Frankly, though, my maximum distance limitation is currently my vtx signal. I'm seeing significant video loss at approximately 1.5 miles with the DJI 03 Air Unit. I am confident I could get more with some antenna mods on the quad and goggles. I am not at all unhappy with 1.5 miles and rarely feel the need to go further. Improvements in penetration and reliability in noisy and dense environments would be welcome and I love to test the new technology even though control transmission/reception is almost never my limiting factor. I am currently running my RadioMaster Pocket controller at 250mw with the RadioMaster RP4 true diversity receivers and have had great results but I have wanted to try true gemini mode. Also, I wanted to say that, in my opinion, most of RadioMaster's upgrades are more than just flash. The Boxer Crush for example comes with AG01 cnc aluminum gimbals stock which are an expensive upgrade when installed after market. I am seriously considering replacing my Pocket radio with a Boxer but I'm dragging my feet because I think RadioMaster will soon produce a Boxer model with the upgraded gimbals, large color touchscreen, and built in Gemini technology at 1W or greater 🤞. I can afford to wait since I'm absolutely satisfied with my current rig. Thanks again for producing such high quality content that I find interesting, informative, and entertaining. Happy flying amigo 🫡 🍻.
Thanks so much for the kind words and detailed comment! It sounds like you’ve got an awesome setup going already. I totally get the balance between waiting for the next big upgrade and being happy with what you have-especially when you’re already getting great results. I’m with you on the potential for antenna mods to push the limits even further. The Boxer with built-in Gemini tech at 1W+ would definitely be a game-changer if RadioMaster goes that route! Keep us posted on your upgrades, and happy flying to you too, amigo! 👊
@Gippslanddroneflyers I use the FCC hack. My distance has improved, but I still see single digit readings at 1.5 miles. I think the next step would be antenna upgrades if I continued to chase distance. Happy flying amigo. 🫡 🍻
@Sonic_Ox yes probably only thing you can do. But there is a video from Joshua bardwell that apparently you need to go into the lua script and change a setting. I need to look it up again. All radiomasters do this it's like a setting that puts it in like a race mode in range I think the packet rate But once changed its night and day difference. More range
Can i use the crossfire antenna on the receiver , i have lot's of them? The 900 of course. I also have some extra 2.4 antenna i would think they are all the same , what do you think?
I'd love to, but as I've said in all my videos about long range RC and VTX gear, the legal distance limit is the UK imposed by the CAA is 0.5km. And since I'm a commercial operator and don't want to jeopardise this, I won't be publishing any long range flying tests - I'm sure there'll be others willing to risk all. In the past, I've simulated things using ground tests and may do the same with this at some point - difficult though. TBH signal penetration performance is more important for the flying I do, so I plan to test that sometime.
I reviewed a 2.5W and 5W analog VTX recently, but if you want digital, DJI O3 is still probably your best option. WalkSnail, HDZero are great, but they still don't beat DJI, regardless of whether you like DJI or not.
They are a similar price, but the Ranger isn't Gemini, so I think the Nomad is the better option. You will of course need the matching receiver to take full advantage. Check my other video about the advantages of Gemini mode ua-cam.com/video/pNbLUcxHDdk/v-deo.html
The RadioMaster Nomad, which uses the Gemini Xrossband ExpressLRS module, does not specifically support FHSS (Frequency Hopping Spread Spectrum) hooping. Instead, it operates using ExpressLRS, which is a high-performance, long-range radio control system that works based on the more modern and efficient LBT (Listen Before Talk) and FHSS technologies, but in a specific way designed for low-latency, high-reliability control. If you’re asking about whether it supports hopping (changing channels automatically within the spread spectrum), ExpressLRS does use frequency hopping, but it’s managed by the system, not manually adjusted during operation like traditional FHSS systems.
Fundamentally yes, but the Nomad has the advantage of the Xcrossband. When the UK winter weather has gone I'll be doing a side-by-side test. Flying is mostly impossible at the moment.
Good review
Thanks
Thank you. Good info. Just subscribed.
@parvezhusnoo8581 Thanks. I'll be running some tests over the next few weeks.

fcc hack will sort that

More range
Appears everyone got these to try as there are so many videos about it on YT , just today
Funny that! 😀

@@redbaronfpv8555 That's actually a great idea.
Been waiting for this to be released. Is there anything else on the horizon for ELRS or is this the last known major milestone?
It's always a good idea to keep an eye on the ELRS discord channel for info. discord.com/channels/596350022191415318/842583674762559488
range test please.....

What would be an appropriate VTX for long range (Preferably digital)?
I reviewed a 2.5W and 5W analog VTX recently, but if you want digital, DJI O3 is still probably your best option. WalkSnail, HDZero are great, but they still don't beat DJI, regardless of whether you like DJI or not.
Would it be better to get this one instead of the radio Master Ranger Micro?
They are a similar price, but the Ranger isn't Gemini, so I think the Nomad is the better option. You will of course need the matching receiver to take full advantage. Check my other video about the advantages of Gemini mode ua-cam.com/video/pNbLUcxHDdk/v-deo.html

what is long range, 80+ kilometers? does it compare to Doodle Labs Mesh Rider?
Radiomaster have apparently tested it up to 26km during development.
Can this do switch mode like betafpv super g (which work with normal receiver)?
The Super G was the first gemini TX module but it's only 2.4GHz and doesn't have Xrossband. Don't be surprised to see that change soon though 😀
BetaFpv Super G TX Gemini....must be comparable distancecwise,(albeit just in 2.4 ghz)🤔🤔🤔🤔🤔
Fundamentally yes, but the Nomad has the advantage of the Xcrossband. When the UK winter weather has gone I'll be doing a side-by-side test. Flying is mostly impossible at the moment.
Great!.. I'll wait and watch your results next year.Cheers😊
