So far, at least on paper they have a 5dB less sensitive receiver, which involve the need for three times more powerful transmiter to have the same range.
Again on paper, the set with 500mW Airwave transmitter should have same range versus the set subject of this thread, using 200mW transmitter.
Some manufacturers has a misterious preference to embed Airwave modules in their products, without any technical explanation of this choice. They claim in several places they use modified Airwave modules with improved performance, but in the online shop pages the specifications are still the same as the genuine Airwave modules.
When we switch from paper to facts, in real world I don't know any user video of a flight at least 9.6km done with an Airwave based system, as was the previous record of this thread for some months, before being busted by Romania team. I don't count manufacturers demo flights, I want to see user flights, with setup built by real users. Preferably with similar antennas, to not compare apples vs oranges.

I guess you could say the new modules have a different layout. The channel buttons are on the bottom but they are only from one shop and I haven't seen anyone use them.

I like these systems for ta few main reasons. They are also low power which really helps with the placement as it doesn't swamp other gear as much. People are showing that they can work well in a lot of situations. Stunt flying behind trees, long range, on copters. I don't see many people doing that on 5.8ghz airwave modules. I don't see many people talking about the 5.8ghz airwave systems. Most of the time i hear more people getting off those systems than staying with them. I know a lot more people using sky-rf systems and getting good results.

Team Romania sure beat Team Germany (as myself and rabe2000 both live in the same country). I don;t think I will ever challenge your record. My goal is still to go 10km as Markus123456 once said when we started looking at range on these modules that you should be able to fly 10km on these 200mw systems. It has been my personal goal since the beginning and I hope this summer to achieve that goal. I hope you guys can break the 20km barrier and fly home That would be a record and a half.

But I'm a little confuse. ReadyMadeRC have stop carrying the FoxTech 200mW because of the poor quality. I've seen a couple of people with blown up TX but here, you seem to be preaching this TX.

Are they all the same? I mean, is the HK 200mW the same as FoxTech or BEVRc?

it is the 500mw that blows up. The 200mw doesn't even need the heatsink. There are a few minor issues with the 200mw, weight, connectors (ground on inside) and the rp-sma connectors.

foxtech and bever and hobbyking are all the same.

Do you guys recommend them? Or you prefer an alternative version from somewhere else?

I agree regarding the heatsink, I removed it from the beginning.

The 200mW version, yes! I like them very much (yesterday i reached 5km with a 10 turn helical and still got a solid picture).
Just make sure you use 2S for the receiver instead of 3s and if you use the tx power out for a cam, make sure the wires are colored correctly (i think some times + and - were labled wrong).

Then nothing will blow up. You also should have a look in the online-manual, to make sure your channels are matching (tx dip switch position is not equal rx dip switch position).

guys, I'm really sorry for your loss
here's something that may help in similar situations.

it's under 50g if you remove the case, I'm sure with a small lipo will be even lighter.

I seen rabe posted yesterday a video showing 4.5km using 25mW, with Airwave stuff.
If we upscale power this will equate to 12.7km using 200mW.
The difference to 15-18km could be either receiver, either antennas.
Anyway, same ballpark, the limits are reached for this band.

I wondering what one can achieve with one of this :

http://www.superpass.com/SPPJ48W.html

And a dipole or something on the VTx.

Off course this is linear polarization and maybe doesnt count here?

Men I would love to have one of this to try...or maybe a 27dB grid like this one:
