    For the RX use either a Racewood or a Lawmate as they don't cause problems with a LRS TX close to them. Both of them are better with the SAW filter upgrade, you can either buy this already done or do it yourself if you are confident with a soldering iron.

    For the TX you should either go with a Sunsky 800mw (also known as FOX-800) or a Bevrc 800mw. If you go with the Sunsky then don't bother with the RX it comes with, lots or reports say it's junk.

    Hope that helps, that's what I'll be doing anyway...
    Hey bud,

    If going the RMRC "special" Rx's you'd be better off going with the Vtx's Readymade sells so the channels match up.... 1258 etc.
    Oh and Pm me before you fly as Im only 10km from you and use the above

    Remember the Golden FPV rule... Turn RX on First, Check goggles for anyone else.. then turn on your plane.

    hmm, so for the Rx I will go with the lawmate then.

    but for the Tx there doesn't seem to be a real consensus. some say RMRC, and others say sunsky or Bevrc.

    can anyone clarify the Tx issue? and of course experience >> theory

    Oh everything I wrote was from experience... just not first-hand experience :P

    From what I can tell it comes down to choice, the Bevrc and Sunsky ones are bang for buck while the RMRC are quality and customer service. They should all perform well.

    One thing to check though is, as ChrisG was saying, what frequencies they do and how they match up. If you are in the US and order from RMRC you will get a TX which is locked to the two US legal frequencies, 1258 and 1280. As Alex said, if you order a Lawmate RX it will not receive 1258 and so you will only have one usable frequency.. Not so good if you want to fly with friends. The Racewood RX from RMRC will however pick up 1258 giving you two usable channels. If you order a Bevrc or Sunsky you will have more frequencies but obviously it won't be legal if you are in the US.

    Obviously the same disclaimer as last time applies, I don't own any of this gear and could be off the mark, so you may want to wait for someone else to chime in...

    I run a 1W LM on 1280 and it has worked fine for about 10 months now - first on my Bixler now on my Z2. But it does not drastically outperform my Racewood-type vtx from RMRC despite being twice the power. I run 2 LM receivers and both worked fine until I put a new IBCrazy crosshair on one of them - that one no longer works, though I am not sure it was the choice of antenna that caused my trouble. I ordered a BevRC vRx to try instead with it.
    another friggin lawn dart. love it

    On the other hand, the LawMate RX is great. No 1258 channel, though. The filtration of the Lawmate is better than any other VRX out there. The sensitivity isn't too good, though. The Digital beats it in sensitivity, but nothing beats the lawmate for filtration. So for parkflying and moderate distance, Lawmate is top dog on the RX. For distance, the digital is best.

    For VTX's I like the 400mW and 800mW VTX. The 800 only puts out 600mW and the 400 is closer to 500mW output. Both are excellent. I like the 400mW better, though simply because it is lighter and cheaper.

    I use the 400mw and 800mw readymaderc sells and they work good as Alex said.The only thing alex missed is you can now have Lawmate with 1258 and also 500mw/1000mw selectable with 1280/1258

    Most of the money I made this year I spent on FPV,the rest I just wasted.

    not sure if this is really the right place, but I have this RX, and I was wondering if I could buy this to get the SAW filter upgrade? it seems like replacing the SAW filter itself would is a rather involved proces, whare as replacing this would be pretty easy.
    reading is for stupid.
