Hi ! I am interested in making co-operation and frequent byuing from you r/c toys. Are they(models JXY-1112609, JXY-1112068) ready to use set. I mean, is it r/c helicopter + controller, or only r/c helicopter ? I know that batteries are not included, but appart form batteries what else do we need to run it ? If everythng will go through without crucial problems we are interested in frequent byuing toys from your comapany. Best regards, Marcin Lisowski trade advisor of: Elmar Company
