Looks really nice, except it sure would be nice if receiver had rssi out.

Analog : The default setting is RSSI output
Working with higher version RF module, Analog port control data can configured as
your radio output CH1-CH10.1-2 ms pulse width corresponding to 0-3.3V voltage

Analog output is Ok. I didn't see it at first on the receiver pins. Very good.

What are others opinions on these posts from Mictronics

Without an LPF on the RF output the TX will generate a lot EMI on upper harmonic frequencies. And since it uses FHSS a broad spectrum will be disturbed.

1. Harmonic: 800-940MHz
2. Harmonic: 1200-1410MHz
3. Harmonic: 1600-1880MHz
4. Harmonic: 2000-2350MHz
5. Harmonic: 2400-2820MHz
6. Harmonic: 2800-3290MHz
7. Harmonic: 3200-3760MHz
8. Harmonic: 3600-4230MHz
9. Harmonic: 4000-4700MHz
10. Harmonic: 4400-5170MHz
11. Harmonic: 4800-5640MHz
12. Harmonic: 5200-6110MHz

The RF output power will be reduced for each harmonic band by several dB but, since you operate the TX near your video receiver I would expect serious problems with video reception.

No matter what I say! There will always be a nerd claiming this wont work in any way....

I'm not the builder or behind the product but I know it have been tested for some time, also with Video link 900, 1.2 Ghz and 2.4 Ghz in the FPV setup without any problem.

The specs and product look good. I hope it is the real thing.

I will make a FULL REVIEW soon.

http://www.foxtechfpv.com/product/Rm...0manual%20.pdf

some errors in the manual.
A. Keep receiver antenna straight, and about 90 degrees to each other
picture reads 180 degrees

I love my lrs but to not have a big metal box attached to my radio would be very very nice.

The integration does look good but has anyone ordered it yet?

Does anyone know if this can click into Turnigy 9x? Seems like they are visually compatible?

It says it can on the page(the JR version) and yes any JR module will fit into the 9x radio.

Does anyone know if it is possible to use 9ch + rssi output?

Give it one more week and I should have mine in my plane

I will also test this on the ground with my car to see how long range I can get on ground.

lol... when you can beat them, join them! good though, a quite range of UHF modules already, competition is always good, a nice way for every supplier to make better improvements.
