DJ SOUL FORCE
Advantages: Much improved over the orginal Syma X5-c. The body has been enhanced to be stronger, yet still lightweight and sealed very nicely. Everyone complained about the X5-C's camera angle, that it pointed downward too much. Well Syma has corrected that on the X5-SW. The new battery compartment is an additional luxury that I love. I really can't explain, but it just feel tighter than the previous versions. I should know, I went through three of them! As soon as I flew it, I gave my old X5-C to my son. And oh yea, it came out of the box just about ready to fly. There are no screws in plastic bag to deal with. All the screws that are needed for assembly (landing skids and prop guards) are in their places, you just need to tighten them up - I LOVE IT!!!
Limitations: The camera doesn't take a SD card, you have to record your videos on your smart phone. I have yet to test that out. Otherwise, for the price, great quadcopter.
