which one should I buy? Why should I choose lawmate or why rmrc?

Thanks
I use the Lawmate as shown in your link....I got mine from Goodluckbuy too...It's nice and small and has the filters built in, but it doesn't have as many channels as the RMRC one.
Not the cheapest VRX but I get a great image and DVR recording from it.
:vulture:
I had a few issues with Lawmate, not so much their receivers but more the transmitters so went with the Rmrc gear. I've had no problems with that receiver.
That Lawmate webpage is a bit potty...
1000mW 8CH Receiver VRX?
'Features' details Video and Audio Inputs.
'Specification' details video and Audio Outputs?
I'm confused...Am I going potty?
I had to make the same decision some time ago and gone with the RMRC, never regretted so far
I've been using a Lawmate for the last few years and its been great. I can't imagine there's much difference in it.
I also have a few of these laying around: https://www.banggood.com/FPV-1_2G-8CH-800mw-Wireless-AV-Transmitter-And-Receiver-p-73201.html?rmmds=search&cur_warehouse=CN (https://www.banggood.com/FPV-1_2G-8CH-800mw-Wireless-AV-Transmitter-And-Receiver-p-73201.html?rmmds=search&cur_warehouse=CN)
Has anyone tried them? I only buy them for the Vtx

In started with the kit on your banggood link. Went out 15k without issue. I then bought the RMRC vtx and didn't see any improvement! #snakeoil?!

Very interesting :) not just junk after all then

Absolutely not Adam. I use the 2 RMRC with eagleeyes for diversity on my GS for my talon (using the same Partom (banggood) vrx on the talon), for no other reason that I paid through the nose for the RMRC vrx's. The Partom vrx's and a spare Partom 800mw vtx that I have spare I use for my trx-4 RC car for fpv.
Just a point to note. On both Partom banggood kits I've always tested the ducky antennas. And on both sets 1 antenna has had a vswr reading of 1.2 and the other hasnt even registered. But I make my own dipoles anyway. In a nutshell, don't trust the included antennas with the banggood kits. But from what I remember you fly with skews anyway. So yeh, I rate the banggood Partom kits.

Just a side note. I've had my RC car out to 700m on the ground with the "cheap" 1.2ghz kit and Ducky's. I've not even started testing yet with a big patch on the cheap vrx.

Adam,
Since you already have the 1.2G Lawmate VRX like me, I buy my 1.2G VTXs from Surveilzone, the 800mw vtx is about £33 and the small 200mw version is about £20.
They also offer a 400mw, 800mw is rather a lot IMO.
Surveilzone have always been good with a fast delivery time, used them a lot, have also had Cameras from them.

Snooze dog, how's the diversity in the Eagle eyes?

Awesome thanks for that! I prefer the 400mw and only got the 800 because it's too expensive at RMRC with shipping and import tax.

The eagleeyes is great. I only use it for diversity, not tracking. I've got the cheap 800mw vtx. No issues.

These are 5v fyi. The banggood Partom ones are 12v. BigT, In use the Partom banggood vtx with my RMRC.

Yes, they work with rmrc rx. Smaller, lighter, less expensive than the fox800

These are the ones I use. And because they are 12v there's no arsing about with BECs.
Partom FPV 1.2G 1.3G 8CH 800mw Wireless AV Transmitter And Receiver

Yes but I don't need a complete set only the vtx that's compatible with the RMRC kit. 5v not an issue either as the CL Racing F4S board has 5 v supply. Anyway only chewing over putting 1.2 on the ZMR 250, I would want to put a module in the spare Dom's as well.

Ah ok. No worries.

Just login to your Aliexpress account and click "contact now" on the product page. Tell them you want to order via paypal and not aliexpress.

Interesting little transmitter at 600mw and only 5vdc....Not available at the moment, but the seller does say it may take up to 2 months to receive via freepost from China with an option to pay recorded delivery instead.
Do you use this VTX yourself Schalonsus..?
I always get mine from Surveilzone myself, I have 200mw and 800mw....but 800mw on a small plane like the Skyfun seems far too much..The 200mw also seem to work well at this frequency though.
Be interested to hear about the 600mw 5 vdc version and how it compares to the 12vdc ones.
:vulture:
Not tested yet myself. But definately will order some. Makes integrating it in the plane much easier with its size and weight.
I always bought from surveilzone too, but a bit pricey at 40$ for one transmitter.
As you can see in the post on FPV-Treff from "vierfuffzig" you can adjust the power of the transmitter by applying lower voltage.
I think transmitter power does not really relate to plane size, more to your flying style. You can easily go 20km with 200mW and the right antennas.
But if you want to fly very low, more power is better.
I have no problem with 800mW in my SkyFun ;)

Downside is having to provide a filtered separate 5v supply for it and the camera....I usually use a 3 S Main Lipo to avoid that and just use the RAM voltage to power VTX and Camera together, this is also the same filtered supply to the FC to show pack voltage instead of using a current counter.
These 1.2G VTX only seem to take 12vdc as a maximum..which is a bit annoying, suppose I could use an adjustable step down reg just on the VTX line....?
:vulture:
Since i always use at least 4S i always have to step down the voltage, so i do not really care if it is 12V or 5V.
5V is even better, because if i fly with Li-Ion battery, the voltage on 4S can drop to 12V and if you use a 12V step down and feed it with 12V input, the output ripple is not very nice. So you would need to use a step-up-step-down converter... much easier for me to just step down to 5V

Yes, but the difference is, most modern 5.8G VTXs will happily run on 4S.....All of my 1.2G VTXs wont tolerate more than 12 vdc....Or less in fact.
A linear 12v Reg doesnt make ripple I dont think..and 4S down to 12vdc is pretty easy?

So I did this but I have not had an answer back yet. I'll try it nice more.
