Please help,
Finally today I got ma batter and went to fly my new quad and what a disappointment that was.

Any way let me start with the setup

Total weight 921g
Motors 4X930Kv
ESC 4x 30A
Props 1045R CW CCW newer figured out what “R" sands for
Battery: 2S 20C 3000mah (full)
FC: MWC MultiWii SE V3.0


So when I try to flay slow trothel up it wants to flip to left, when I do it fast it lifts up 60cm and stay there for 2 seconds then it drops like it doesn’t have enough power to lift.

So the first question is can this setup fly.
If yes why it doesn’t!

Thanks pleas make me happy flayer!
;)

"R" stands for right hand rotation. Make sure you actually have the right props, otherwise the setup should be fine.

Salamala, You're running a 2S battery. I would use a smaller capacity, but higher cell count battery.

ie the very popular 3S 2200 mA battery would work very well with your setup. 2S will really struggle to get that frame off the ground. With 3S it should perform well.

Nebbian you are killing me!!
I just got this 2s battery and now it’s useless!?!
Part 1:
Anyway if you are sure that I need to get 3S I can get my hands n a 3s that’s 370g would that be to heavy this one that I have now 2s is 180g?

Part 2:
What I also have a problem with is 1000 – 15000 – 2000
I am using:
TX: FlySky Upgraded 2.4G 9CH
RX: FS-R8B

FC I uploaded the newest Conf.h I think V 2.3

I can set up the middle to 1500 but then min is 1062 and max is 1963 if I change the settings on TX I can get 1000 but then the 1500 is not 1500 and the max is not 2000 and whatever I do on TX max cannot go over 1970

Thanks for any answer

Try that 3S, it will be better than your existing battery, but a 2200 will be better still.

Part 2 really doesn't matter. If you're able to get 1500, and you can stop the motors and arm and disarm, then you're good to go.
I'd investigate putting ER9X onto your Tx, it rocks. https://code.google.com/p/er9x/

Props look good, but 2S really won't get you off the ground with 930kv motors.. they just won't spin fast enough.
Make sure the motors spin in the right direction.. i.e. in the direction of the blunt, higher edge of the props.
The transmitter should be able to do what is needed according its description.. you need to set the endpoints higher till you get from 1000 to 2000, then using subtrims, you adjust the center point to 1500.
Also check if all channels are moving in the right directions.. you might have a channel flipped, that would cause it to act strange.

3S lipo and you're good to go! And no. 1100g is not to heavy for your setup. I have same motors (1000kv) and 10x4.5 props 3s battery...my quad weighs 1300g and goes up at 50% throttle.
