Quadcopter frame recommendation

Hello all. Last 3 months i tried to build my own quadcopter, and after finishing it and tuning it, the motors didn’t give me enough thrust to fly and i discovered it was because of my frame weight.
So i would be glad if u can recommend me a frame that i can use with my components:
1- 4 flycam motors 925 KV
2- ESC 30A
3- 14.8V, 4000mAh, 40C, 4S LiPo Battery
4- controller: stm32F407 discovery kit
