Yeah im just getting my head around all of it at the minute!

Id been flying FPV on 2.4 for about a year now and been out 3.5km with the Spectrum gear  :o and your antennas so i thought it would be as simple as replacing it with the ezUHF and increasing the range to 10km+!

oh how wrong i was!  :laugh:

Yeah steep learning curve ain't it ;)

It's taken me an age to get mine sorted as had no one to really help me through it, worth it for a good system though, glad my skews are working well for you too!

Wow 3.5km on spektrum gear - I never got more than 900m with a DX8 & AR8000!!! Is yours US spec tx?

You'll get there mate, but be aware 10km will probably be the absolute limit of the uk spec 100mw 459mhz firmware tbh.

yeah that was me being blissfully unaware of what was about to happen, the AR6200 was on the tail so had perfect reception allowing me to go to 3.5km however as soon as i turned the connection was awful! had dropouts of maybe 20 seconds and then a couple of seconds to point towards home then lost connection again. somehow got it back in one piece :D I bought the DX6i from Sussexmodelcentre so im assuming is uk? :laugh:

Thing is though, most people say the most fun you can have is within a kilometre range anyway so im tempted just to sell it and stay on 2.4

Er yeah there's the good old Spektrum I know & no longer love lol ;)

Yes you normally pitch up near the interesting stuff so you can dick about more & fly lower.

I'd say keep at the uhf to give it a fair go as it's a lot better than 2.4 for signal penetration & will carry you much further than 2.4 too, just takes a little bit of work thats all.

Noisy environments dont help either 2.4 or 459 & you will notice large drops in range with both frequencies when flying near corresponding interference sources. (e.g uhf masts for 459 & towns etc with lots of 2.4 wifi for 2.4 rc)

If you're gonna sell the UHF to stick with 2.4 rc go FRSKY! I've seen 5km done on that stuff!

Is that a round-trip or LOS?

3.5km LOS is very, very, very impressive for any 2.4ghz system let alone 100mW Spektrum :)

..Oh and recent 250 convert!

Impressive for an almost one-way trip lol ;)

UHF systems should be easy enough to install and run. The problem in my opinion is the EZUHF.

It's simply not as good as everyone seems to think. I know you can point to a hundred vids of people going long range with it, but when applied to the general FPV population you've got tons of people who are having failsafes within 2-3km. I know you can say it's external interference and therefore it's not the fault of the EZUHF but why is it other UHF systems aren't having the same problem?

My DragonLink V2 just went 10k on low power and I'm a few miles away from Crystal palace with megawatts of digital TV and other crap. EzUHF won't do half that, even on the older firmware on high power with identical plane setup.

I'm sure this will change now that Trappy has kicked up a massive fuss and Immersion are taking the problem seriously and bringing out new firmware but it's been lagging behind for the past 2 years.

It's a shame because in every other area EzUHF shines. Great hardware, numerous options, lovely software, firmware updates.... and now the new EzUHF will have 2W of power. Lets hope that solves their range problem.

Personally speaking despite my feelings for EzUHF I have faith it will get better, I will buy the 2W module based system because I'm a sucker for integration. And by then their firmware will have been sorted out, and worse case I can just abuse the airwaves and switch to win-mode(2w)

yeah davey, 3.5km LOS.

was just on a bixler 2 with the AR6200 and satellite mounted on the boom and tail!
