This is my first 3-inch build, and it's a blast to fly. Since it doens't have to carry around a seperate camera, it has plenty of power in a great light-weight package.

Weight:

Without battery: 155.2g
With 650mAh 4s: 222.0g

Nice build! And very beautiful pics! I also ordered the 1306RS with 4000 kv. How long is your flight time with how much mAh?
