Be careful if your going to buy a quadcopter from them. a month ago a asked them if I sent them all the parts need it how much will they charge me to build a quadcopter for me. The response was $100 and it will be ready in one day. I send them all the part, APM flight controler, escs, motors, props, frame receiver etc. It's been over a month now and still have not received the quadcopter, the person who supposedly build my copter had a car accident. He keeps telling me that he will send the quadcopter but he never did. Now he will not answer my e-mails (hope his not dead). I have all the emails to prove this.
