I received an Avistar from Fedex today and it's different than the one I have been flying. My original one (Avistar RTR select) has a metal rod in the wing and an alignment pin. This new one (it's the $99.00 one from Tower) doesn't have the pin or the rod. Did I miss something in ordering or have they upgraded the planes to include the rod and pin and this recent one I received is an older version? It seems without the rod that the wing could be suseptable to collapse.
