One would expect them to know the difference between two different brands and one without spoilers and landing gear and one with. Right? I looked at the wing and they have made some changes so this might actually fly. Why they sell three different aircraft that is actually just one when it shows up.. I don't sell the point of having all those picture of the insides and pieces and then sending an entirely different aircraft? I have several quality scale gliders including a 20 year old Graupner Ventus 3m that looks like new after all these years.. Of course it cost more but I doubt if this will last a season... Ok for the price but it would be nice to get what I ordered! I don't remember checking any boxes that said substitutions permitted!I have seen a bunch of them snap in on YouTube and really wanted the plain Jane discus I ordered.. Got any helpful hints on improving the behavior of this one I would appreciate it.
