FatShark pushing the limits of low power FPV...

1.6km on 25mW... Check the video description and top comments for gear used. Pretty awesome.

First... not fatshark, They do goggle and some head tracker, and some receiver for their goggle, it's all ImersionRC stuff.

But, Fatshark and ImersionRC work quite closely together.

They we're testing new patch here

probably with the diversity receiver

And if you look... they stay all LOS. I don't say it's not impressive... cause, it is, it is really really impressive. I want to try back a 5.8Ghz setup... The portability of the system is quite hard to beat. still, I'm not too confident! Never had good result til now... as soon as you pass behind a tree... you loose a frame... but, may be I was doing something wrong!

I lower all my vTx power now, I usually fly with a 400Mw now. And I've did near 2km on my tri for a test with a 150Mw yeah, LOS.

vTx power is way overated. It cause more problem than it have advantage! The only place I'll be using 1W lawmate will be on my Zii, cause, first, I go quite far and quick with it and I prefer to put an omni antenna on it cause i'm afraid to broke the the cloverleaf with the wind and I believe that it affect the stability of the craft at that speed!!!

I know, Kenny, that's why I said read the description =P it's the FatShark crew flying from the roof of their warehouse.

Oh... my bad!

did not notice that was a fatshark channel!!! so you right... they still using ImersionRC video equipment stuff

**wooden** · 02-05-2013, 06:01 PM

I'm tempted to try out some immersionRC stuff soon but it looks like it's all 5.8GHz? I'd like to know why they focus on the higher frequencies so much when they're so susceptible to being blocked by trees/buildings/etc.

I really like their stuff...

My EzUHF rock... and I also use some EzOSD and really like it. But, I don't like their video equipment, mostly because of 5.8Ghz. They also have a 2.4Ghz system, but... if you use a normal tx, or... fly with other that have normal tx, you're screwed!

But, I've heard that they're working on 1.2Ghz stuff

in the UK 25mW is as powerful as we can go on 5.8ghz - 10mW on 2.4Ghz - we are also only allowed to fly line of sight so to see this range is possible in a LOS situation is really cool

not really any option for using frequencies below 2.4Ghz for FPV either so 'stuck' with these options - unless I don't mind breaking the law but I don't want to do that and get Quads / FPV a bad name

Technically we have to fly LOS in the USA, too, but obviously most people don't pay attention to this =P

Pretty crazy that your max power is 25mW though! Way too weak =/

**Pollitt** · 02-12-2013, 07:18 PM

there may be a way around it so you can up the power if you have an amature radio lisence but that's a lot of work and cost for a very broad ranging topic to get a very specific thing out of it.... and I would still be limited to LOS anyway officially so not worth it too much. I'm thinking of using a screen on a ground station so I can fly solo and use FPV to line up the camera for nice photo / video. Won't be for a while yet though

We have to get amateur radio licenses too (HAM amateur), they're only $15 and a pretty simple test, though. Can't imagine the equivalent license for you is much more expensive!
