I know nothing of amps and oms and.. whatever else. but this is going to be my hobby. I purchased this kit. And I need any general advice anyone can thing of, also, the esc says I can use battery 4s but the motor spec says up to 3s. Can I use a 4$ since it goes throu the esc first? Here are my specs of the kit I purchased.

I had to let my eyes stop watering there for a second. For general advice: watch lots, and lots, and lots of youtube videos. I mean days worth. Flite test, rc model reviews and painless 360 are all great channels. As for the battery question, I would stick to 3s, Which means 3 cells in series. A 4s, or 4 cell battery would be way too much for someone who has never flown before.

Is your kit RTF? If not you'll need a soldering iron, heat shrink, battery connectors, some spare 16 gauge silicone wire, and a myriad of other random parts, like nylon standoffs for instance.
 
Well I hage flown befote. I got a micro toyone for 30 dollars and I was in love. No the kit isnt rtf. I know I need to solder the esc to the power didistribution board. I have watched muxh YouTube videos and still I need advice. Specific advice to my specific specs.. I want to solder bullethead connectors on the esc and motors thou for easy reconnectability. But still... any advice? Anything anyone can think of.. like.. the cc3d im getting? Whats the best open source to use? Im wanting a fast quad that can go high.. and do flips.. and eventually fpv. Mmmmmmmm. Fpv. Mmmmmmm
 
All four esc's will need to be soldered to the power distribution board, with a common lead for the battery. Your cc3d flight controller will run libre pilot, and most motors/esc's these days come with bullet connectors already on them, although you won't be needing to swap them out barely ever, and most people cut the wires on their esc's and motors short, and just solder them together to prevent having large jumbles of wires out on all of your arms
 
First hobby grade quad? That's going to be quite a handful. Don't even think about 4S for now. BTW that's a pretty impressive list. Can you post a link?
 
Why can't I use larger then 6 inch blades on my mini quad? Also.. what really limits my ability to put a massive motor on hete. I.e more then 2300 kv. Also how would this mini act if I plike an 800 kv motors on it? I hope I make sense..
 
The top plate on the blackout is a little different, the zmr is its own style frame. I actually have a FPV racer built on that frame. For how much they are asking, it's a pretty good kit. Everything is about middle of the road, as far as quality goes

The lower kv the motor is, the more torque it will produce, in a sense. You need larger props because they spin slower, so the larger prop produces more lift. The reason you can't put props longer than 6 inches on is pretty straight forward, they will hit the frame.
 
What if I put a really deep spacer between the frame and motor so that the props clear the frame. Would there be any perks to larger blades if this were possible? Also, fpv is whay im striding for. But that will have to be the very last thing I do.. how fast can your racing wuadego? Do you use a little 1.3 nano whatever batteru with a high c? Which ia the best you wpuld recommend?
 
This is a 5 inch prop, you can tell even a 6 inch would be pretty much scraping the supports for the frame. There is no advantage to having anything bigger than 6 inches, at that point you would need bigger, slower motors, which means you need bigger esc's because spinning a larger load is gonna pull more amps. You would need one hell of a spacer anyway to put the props above the battery and the 5.8 antenna (mine isn't on, I have a new Tx in the mail and I've had this apart rearranging the electronics). And yes I use 1.3ah 45c batteries 20160307_014339-480x854.jpg
 
Yeah, a 5.8ghz rhcp antenna. Once it gets nicer out im going to find a nice field and a stupid friend willing to stand at one end of it with a radar gun while I fly at him, im assuming it can do something like 50mph. Racing isn't really about straight line speed though, it's about being able to make tight turns and quick directional changes.
 
I have multistar elite 2204 2300kv. For the range of motors that will get a 250 in the air the most is gonna be probably 2400. More kv isn't always better, it's about the balance between kv, prop size, and amp draw
