I recently purchased a helicopter from helistore.com, known as RCMart on the web, and Helistore on eBay. I recieved the helicopter a little over a week after the auction ended, and considering they ship from China, thats pretty fast. Now, for some reason, the motor's bad, so I tried to get a replacement. After a number of emails, which I believe were misinterpreted, we have finally come to an understanding and they'll be sending a new main motor. I guess it just took a little negotiation. Overall, I'm pleased with their fast shipping, but satisfactory when it comes to getting replacement parts. But, I guess you have to be careful around international vendors.
