I maidened the beautiful Beaver last night. It flies wonderfully with the servo setup throughs in the manual. I only ding it on two items.
Reflex installation positioning. Unless you want to create an access hole in the side of the fuselage, you cannot connect a USB cable to verify that the Reflex is set up for the Beaver. It seemed to work okay; just not sure it is working how it is supposed to. With only three flights on a calm night, I could only verify that the beginner mode prevented full maneuverability.
The second point is the Landing gear, specifically the axels. One of the axles bent on the second flight. Note that the axel is only available as part of the complete landing gear set. I'll upgrade the wheels with air tires, Dubro axels, and collars. About the same price as replacing the complete gear set.
