Do Blade actually do any R and D??

[KevDavies]

This is getting daft! Yet another Blade product with issues!!

Now it seems you cant use the 350QX quad as an FPV platform with Go-Pro and the likes on 2.4Ghz or live video streaming if you will

Its not really a new issue. Has been done to death in FPV forums.

The same is true for any fpv platform, when using 2.4GHz video equipment. Nothing to stop you using a different frequency video tx

[KevDavies]

Well no, Theres plenty of other units to use, but seeing as it was actually designed to use the go pro, and yet its not compatible with it! Own goal me thinks.

Yeah, wasnt there a guy on here who crashed a heli because of this??? Using the Gopro wifi whilst flying?

thats not true, as you should not use the WIFI enabled option when FPVing I think you can even find that detail in the manual or even on the gopro site .. anyway, thats why the new DJI product for example uses a 5.8ghz TX - but this has the limitation that its even more depending on line of sight ...

gopro compatible also only is meant for the mount itself not for any other feature, AND you wouldnt use the WIFI for FPV for example anyway as this has 3-6secs delay and is very unstable, we tried it once on a quad and after 12m out the wifi link was actually gone ...

isnt it even in the bmfa handbook that WifI, bluetooth (both 2.4ghz) etc can interfere and shouldnt be taken to the flightline either?

[Tim Procter]

Glenn Bishop had a large Logo heli crash while using the Wifi on his GoPro camera.

Not recommended.

[Boggy]

Since when was it released as "an FVP platform". its designed use was amateur ariel photography.

So could the same be said for using a blue tooth dongle for adjusting things like vbar settings in flight?

Probably. So if your model crashes and you have a BT module powered up and running don't cry wolf. lol.

Disagree with that... Bluetooth runs on a different wave length. My 550 has a BT module permanently installed and has never caused an issue. The only danger is if someone hacks into your vbar while your flying and resets it... but that just isn't going to happen.

Theoretically yes, but the main problem is having the transmitter saturating the band and sat right next to the receiver. Both the bluetooth dongle and the receiver, are both receivers, so interference between the two is going to be minimal. Edit - brain freeze, the bluetooth module is a transceiver (both receives and transmits)

With the bluetooth protocol as I understand it being much lower power than our Tx's (think 10ft line of sight or similar) it is very unlikely to cause a problem. That being said, I cant see the point of adjusting the vbar in flight, far to risky that you push the slider too far or there is a software glitch.

No it doesn't, Bluetooth runs in the 2.4-2.485ghz band, rc control operates in the same ISM band of 2.4-2.5ghz... Anyone who says they don't operate in the same band is mis-informed.

The spread spectrum nature of current control systems will take care of it in general, but the problem is a simple one of who can shout the loudest. Get far enough away and your tx is a very quiet voice while your bt module is still just as loud as ever. At some point this overwhelms the front end of the reciever and your tx's voice gets lost in the background.

For line of sight flying this should not be an issue IMHO... If the rx has decent filtering then the range should be quite far before it gets overwhelmed. It will however not be as far as it would be without the BT module going.

Lol dont do it myself bit know a few that do

Thanks for the info - just had a little read on google, as you say both bluetooth and our RX gear does run on the same frequencies, however they both use frequency hopping so the effect is no different from say two TX's being used at the same time.

However, as you say, as distance increases it may become increasingly harder for the RX to listen in and may loose connection earlier.

But from actual flying, I found the BT unit makes no effect on it and I do fly a bit far away at times...

Doesn't help that the vbar is mounted inside the frames on my 550 so theres no easy option to unplug/plug the module in each time.

just use a 35mhz tx/rx on the heli/quad/fpv with the go-pro etc on 2.4ghz
it will cure the problem
