FPV Support/Suggestions

[CorsairRulez]

The internet has not really helped me understand to much on what equipment I need for a FPV setup.

I don't understand how people record in HD and use FPV at the same time. Is this possible through Wi-Fi or is this the slower method?

I have a Cheerson CX-20 and want to know a decent setup and the equipment I need to record and FPV at the same time.

Any help would be much appreciated.

Hi mate lots use the gopro and while this records to its card they link up with 2.4g blue tooth wifi link or wire up to a 5.8g FPV transmitter and then use goggles or a monitor , but there are loads out here If you watch rcmodelreviews on you tube Bruce does loads on FPV systems and how and what to use and how to make your own parts here is a link

Hey man,
Thanks for the info but will the 2.4 band on the go pro mess with the same 2.4 frequency on the quad?

IT can do thats why look at the 5.8g , its getting harder these days as transmitter are now in 2.4 and 5.8g FPV comes in 2.4 and 5.8g plus watts In the EU you can only have 2.4 watts output

OK nice one.
Are most of the action cams out there possible to record and FPV at the same time such as the sj4000 or the mobius.

Here is a post that I made an hour or so ago, goes right along with what you are asking.


You really need a dedicated camera, because gopros (mobius and runcam also) have serious lag, so if you do get one of these, (if not for the lag runcam is really great, and cheapest) The three I just mentioned are mainly for secondary recording devices, to give you nice clean video. Where as if you get a dedicated camera you will have basically 0 lag. The run cam is as good as the mobius if you are using it for a secondary recording device, and is is somewhere around $40.

Take a look at this post I made, it provides a few different options. I suggest that which ever one you get you have a 32ch Vtx if the set comes with no reciever or no video transmitter, because the 32 ch one will work with basically and 5.8ghz receiver. For someone such as yourself this may be an option (full FPV set, and best bang for your buck I have yet seen).

Hi mate George has covered the lag problem

Wouldn't 5.8 Ghz be the overwhelmingly better choice because of less interference from other signals on the same frequency as 2.4?

 

[GJH105775]

5.8 and 2.4ghz are most used/crowded frequencies available right now. They are chose because many others are not legal, and these have a wider bandwidth. 5.8 ghz will do better video quality than a lower frequency. If you are not flying in lets ssay a city they are good choices. These are the most used in FPV. For a LRS people use a lot of lower frequencies, because a lower frequency will travel further and penetrate better. You also don't get RFI as bad. You can fly around lets say a wifi router, witch operate on either 5.8 or 2.4 ghz because both the quadcopter's transmitter and the router have adaptive frequency hopping (shown in image for 2.4). Notice the ones on top, that is one band(a set of channels) some devices can only hop around on one band, allowing even more devices to be together.

Here has a little simpler way of comparing different options, but unless you are getting a LRS (Long Range System) 2.4 and 5.8 are probably the best choices.

Also here is an chart regarding IEEE 802.11 (computer tech's way of saying Wi-Fi because it was hammered into our heads and we have yet to find a use for it )
