Simply stated stay away from flatouts. If you build them correctly they fly ok not great by any means, if anyone would like to tell me im inexperienced builder if you have 35+ foamies built under your belt. if you dont believe me i worked at a hobby shop and part of my job was to test out new planes. i will be glad to talk to you. they just do NOT perform like others of similar cost and size. i fly with some of my regions best pilots and now a single one enjoys their flight characteristics. why spend all that time doing little tweaks here and there to only make it fly good when you could take the same amount of time and make an airplane GREAT!!
