I Have a DM007 quadcopter. I need some batteries and would be interested in buyng them and pay with BTC.
Will use escrow.
DM007 quadcopter pretty much works once you've charged the battery... Will use escrow.
The controls are very sensitive and you will crash! You will also need a large, clear field to practice on fly ... Purchased the crash pack, and an extra battery. I recommend the purchasing of DM007 quadcopter and the support seems to be there for any problems. 
Now i bought Hubsan X4 H107C Quadcopter. Here is good article with examples http://jonsguide.org/best-top-mini-quadcopter-reviews/...
