Please help rc timer spider power issues naza lite

[Marrrr]

Just finished installing a Tarot 2d Gimbal on my RC Time Spider frame (450).
I added LED lights and a TX for video.

Since Completion of built (adding those three items), I can no longer take off.....
It feels like there isn't enough power or something???? It wants to take off but just doesn't have enough power.

Before those items were added I noticed little power in the throttle. In Manual you felt it but not in attitude or gps. But still flyable.

Ive tried all three different flight modes and still can't get it take off or stay in air just wants to come down (throttle on controller fully up) (after a foot) or batteries just Die instantly.

I also tried just powering up the quad and same thing.

I am using a NAZA Lite with gps
Devo 7e Controller
i have Tmotors 2212 980kv
using 9x5 carbon props
all 3s batts

Please help... I don't know what else to try...

Let me know if pictures will help more than happy to post some.

My auw should be around 7lbs

HI mate most guys that do FPV use 4 cell battery 5000mah up , try just running quad no fpv and see what happens if it flys then your need to up battery or run fpv on its own battery but this all add weight use ecalc to work out which you need to change , my mate just built the mighty midget it has an 1 hour hover time but is running 15 inch blades and 3 batteries
