Lawmate vs. Rmrc ??

[SnoozeDoggyDog]

Cheap and good transmitter, has around 800mW

out of stock on aliexpress atm until they have a brand name, aliexpress policy...
but you can order direct via paypal, just mail them

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

So will they work with the rmrc eu kit rx?

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

Can't seem to find an English translation of how to order on the page or find the site, any ideas?

These are the ones I use. And because they are 12v there's no arsing about with BECs.

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.

  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....?

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.
