How big is the tail wheel, or is there something else holding the tail up? I see neither in the shadows with the angle of the sun, but it sure seems to be sitting in an “unusual attitude” for an empty tail dragger!


They just had it up to show off the lines a bit better.

Obviously a Pilates Porter is the best choice unless there are budget constraints

There is a new kid on the block.
The creator of the Badlands Traveller has designed his own wing, and it has set the STOL world on fire. 26 mph stall and 135mph cruise speed. Almost unheard of in the off airport world.

The Traveler wings appear to be closed up at the factory. Searching online I could not find any photos of the structure or build videos for the wings. Some rib photos were about it.

I am curious how they bond/rivet the carbon fiber ribs to the aluminum skins and how they tie the forward and rear spars together to have a single wing strut mounted behind the forward spar?

This has been tried before with a constant chord wing on the Hornet LSA but results were not good. Nothing else is built this way that I can find.

Static tests in torsion and flutter tests with deep chord control surfaces and single strut mounted well aft on the wing?

Just to compare an Aero Commander Lark has a constant chord wing and the strut mounts directly to the forward spar. Aeronca Sedan also has a single strut constant chord wing and the strut also mounts to the spar but the spar is further back than others.

Might be fine but looks a bit odd.

Is this the video of "own wing" on Badlands Traveler? 2 years old.

Skip to 25:00 for Clint's wing description. Cessna airfoil with cuff.

I have attached a few photos of the wing design. The truss design for the strut is nothing new. Rans has been doing this for years. The ribs are foam core sandwiched between composite laminate. The rib is glued to the spar. There is a wooden cap on each rib and the skin is glued and screwed to the cap. The wing is incredibly strong. It has been tested to over 6 g's with no deformation. The roll rate and overall flying characteristics are as perfect as you could ask for.
I will have my plane back with the new wings sometime in January, and I cant wait to start flying it!

Thanks Douglas. Very odd but sure enough the Rans S21 has a similar truss with added diagonals. Quite different attach fittings.
