Mud Duck Aviation Forums

I get this question occasionally: "Can you roll a Mud Duck?".

In the past I have stated that the undercambered wing generates a lot of lift (only on the underside) that it has a tendency to prevent it from rolling over past 90 degrees and if you did get it to go the rest of the way over it would likely dive down (or try to recover to upright by pulling out essentially making a "Split S").

Well, at least in the case of the Mud Duck Sport, I have video to prove that it can be done.  One of my customers powering his Sport with a healthy electric motor and using the optional ailerons pulled off some rolls.  When he told me I could hardly believe it so he videotaped it the next day and posted it on RCGroups (follow link):
