Nice Swoose!
The down-side of the set-up I made is weight. But I had a HORRIBLE landing today and spun the model, bending the forward gear strut on one side . . . and it was ready to go again within 20 minutes of my getting home.
You'd have to scale it down for a .40 size - I used 1" aluminum tubing for the bases and cut then out with a hacksaw.
