RANGE? Immersion 600mw tx, with Spironets
- Thread starter lotusman
- Start date
The signal break-up on the video may be down to the fact that at 800m+ the P2 is disappearing over the hill. You can't really see it in the videos but the ground is actually gently sloping up. If I flew it higher I think it wouldn't be quite as bad as that.
I agree with Ian, I don't think the Black Pearl is the problem, the IRC600 is clearly worse from the start with static, interference lines etc. If you look at the Fatshark 250 videos it's nowhere near as bad. I'd be interested to repeat with one of the other 400 / 500mw transmitters just to see.

Lightbridge is nice..... but seriously expensive!2trickpony said:

Yes you are right, the immersionRC 250mw video looks better yes.
Waiting for your test with the immersionRC rx.
Fantastic review Goldfish. Way beyond the call of duty so thanks very much for these tests. The 250 is the winner over the 600. Flew my rig again today and got total loss at around 450m. Conditions and line of sight could not have been better. Quadcopters advertise the 600 with black pearl and spiros as the very best you can get at the moment. These test results show that is not the case. I am certainly going to make changes.

The 250mW seems to work with everything that uses the same frequencies, yes.
Shrimpfarmer said:
Agreed. Great review. One thing to note: the most important thing other than having compatible equipment is the placement of it on the P2. The further apart you can get the 5.8GHz vTX from the 2.4GHz receiver antennas, the better both will work. I currently have my vTX inside the P2 with the antenna coming out of the bottom but I am going to move it. I want to find a nice slim CF mounting plate that will stick out from the back to mount the vTX and antenna. Trick is a mounting plate that still allows easy access to the battery that is super lightweight.

It's not the antennas that are the issue. It's the receiver. Which are you using?
ianwood said:
If you find one, do let me know. I am looking for the same. The problem seems to be battery access as you've pointed out. Most of the ones I've seen so far really don't allow for easy access.
These real world tests are interesting but the overall picture is still very confusing. Some are getting good performance and some are not.
As someone who is about to go for Quadcopter.co.uk P2 FPV combo I am now hesitant. Hope this thread continues a while yet.
What would be really good is if someone who has a Immersion 600 and black pearl who gets good range will also post a video with telemetry?
Any takers?

Not had a chance to push mine too far out as yet (due to location) but I have
not really experienced any problems up to 200m.
I do have a TrueRC 5.8 Crosshair on the Black Pearl, this seems to be active for almost
all of the flights, with an occasional switchover to the Spironet.
I flew with another member last weekend, and he did comment my BP picture seemed
more stable than when he flew with Shrimpfarmer and his BP the previous weekend
I am a bit short of time at the moment, but I do have an Immersion RC 5800 Duo V2 I could
try should I need a comparison

I posted one (over 3000m) and then made it private as I didn't want to catch attention from authorities, flying too far and that area...
ImmersionRC 600 + Black pearl + Stock DJI radio and receiver. Gopro footage + iosd mini recording.
I can give url and password to those interested (PM only).

That sounds encouraging Dave. Any chance you could film a test similar to the others posted here. I am itching to ditch some of my components to improve matters.
As another person commented on the price, what about the mostly true phrase "you get what u pay for"?
How can DJI charge so much more for their VTX kit but Blackpearl can sell a monitor, battery AND VRX for much cheaper?
Why are DJI and other manufactures charging so much more? Is the quality of the transmission better? Or are they just getting away with a very high profit margin?
Lots of questions I know
Sure people are getting great results with the cheap blackpearl, Boscam kit but perhaps they are flying in optimum conditions. The more expensive kit may have higher tolerance to less favourable conditions thus work better in most real life cases?

I will see what I can do, I am off to California next week, but I may have a some spare time
over the weekend if the weather is OK

So I have just done a range test with the above setup and here is the video:

It was really windy and the P2 reached just over 60mph on the return leg with the wind behind me. :shock:

Blimey 2trick, that is an amazing improvement over what I am able to achieve. Those results will do for me. What and where do I get my hands on what you are using?

Thanks, well the antenna set for the vtx and BP are here:
http://horizonfpvantennas.mybigcommerce ... mrod-rhcp/
and I bought an extra nimrod for the BP for diversity (although the BP has NEVER changed to that antenna!!):
http://horizonfpvantennas.mybigcommerce ... 8ghz-rhcp/
I still think the IRC600 is not matched perfectly with the BP though.......
Waiting for someone to try the IRC Duo5800 :?
Cheers
