Hi:can anyone tell me if the Birdi and the Kange ones are the same.I see the Kange was apparently and ARF.Now that I see the one is an ARF maybe they aren't the same.Friend has the Knage one and loves it and wants my unbilt kit of the Birdi but maybe they aren't the same?He loves his and is such a great flyer thought the Birdi was the same but now not sure now hate to see him disappointed if the Birdi isn't as good a flyer as the Kange!Thanks!
