@hangingthough, how much are u ready to invest in this? because there are better more long lasting options that come for a little bit more than that LHS's offer.... u can go for 2205 2300 kv motors and better ESC's (FVT little bee or DYS 20a blheli's) that are a great option... buying an ARF means that if something goes wrong u may not have another option to buy just the damaged part but the whole set of the part... so basically a bad crash costs 4 times of what was damaged... and there are too many frames out there! and 5030 are a bad choice of props that every ARF sells :P 5040-6040 for a 2300 kv motor gives thrust and less noise ;)

If you are getting the ZMR 250 frame you should get the ZMR power distribution board from quadkopters.com instead of using a separate PDB. It is also better to invest in 20A ESCs. Also, you'll need a 3S LiPo of around 1500mAH and a Rx/Tx to complete the build. Are you going to buy FPV gear too?

Terrible advice, don't do this. Always better to get a separate PDB, I recommend the matek ones.

@cycloned: it seemed to me that having the PDB built into the frame would facilitate an easier and cleaner build.
Anyway, I am here to learn, so can you please explain why a separate PDB would be better?

If anything goes wrong with the PDB since u will crash, it's easier to replace and the upgrades also will have enough space as u can stack the PDB and FC (better CG as FC gets a little lift, closer to the batter :P ), and crashs will be more forgiving as the PDB plate can crack too, it works out cheaper and safer...

Yup, as Rathi said, integrated PDB is more vulnerable to breaking. It's better to have a carbon fiber bottom plate with the PDB mounted inside on standoffs.
