Had a problem with the plane out of the box so i emailed the factory and they are sending the replacement parts so they are standing by their product. So discount the previous review. May take awhile from China though. When the parts come in I'll re-install the RX and SX's. Want to use it to teach a friend to fly and the stabilization will be good. Sorry about the first review. There was a little miscommunication at first but all is resolved. Thanks Skyartec (Posted on 1/8/13)
