In this case, the "wingerons" are the upper wing of a Clancy Stagger Bee. (bi-plane) The lower wing gives the stability while with the wingerons, you have great control. Imagine 1 roll per second but flying at almost stall speed.
Unfortunately Hobby People, who distribute Clancy exclusively, are not producing the plane anymore. Waiting for a new laser cut setup, though no due date as yet.
I'm anxiously waiting to get one.
