These are all clones. Are you looking for original or clone? I have bought from quadkopters and it is excellent and very reliable.

I meant to ask whether he was looking for a 3DR produced one. I have seen that thread too. I asked because some clones may be of inferior quality (fakes). And please don't call me sir, I'm only 15.

ok , but the 3dr board is about 4500 and compass is 2000 than power module.. it almost cost about 9k for kit. if u want to spend 9k i would recommend naza lite. for 10k

I think you are mistaken 4K is the cost of a clone plus 2K for GPS and around 500 for the power module. The 3DR produced one is $200 for this combo in the US. Naza Lite is 10000 without GPS right?

yes sorry for mistake...   

Guys ,  as a opensource h/w these boards are all same, but, the build quality, as we all know varies, for that reason buy only from top rated sellers. and look for 3DR logo, if you insist on contributing to 3DR for their humble work, And getting 3DR produced APM board.

can anybody tell me difference b/w naza lite  vs naza m v-2 vs apm..

Go for APM if you plan to use telemetry module in future. Its two way communication on the fly once APM is tuned and setup .

I mean guide the plane via waypoints on your laptop via gcs software.shows all of plane data too.check wiki for more info.
