Simple 2 axis servo gimbal for SJ4000

This my version of camera gimbal controlled by servo. I am using DJI NAZA M-lite to drive it.
It is very light (75g without camera!), easy to set up, enought stable, camera fixed well but most problem is cheap servos. I am using standart 9g servo with metal gear.
Here is the video:
