RONDO Technical Features

With 58 cells, mini-ribs and aspect ratio of 5.7, the RONDO is high end B.

But beyond that, we have developed new technology around NITINOL rods!
The new neoprene padding on the leading edge distributes the pressure of the Nitinol rods over a larger area and makes the wing nose significantly more robust against abrasion.
Nitinol in general is offering very easy packing and low stress by being very form stable. Of course the takeoff behavior is outstanding: a must have for a modern biplace wing.

The RONDO is using a new type of “double reef” brake system. Never ever the brake pressure on a tandem was that low, with still having full feedback and control!

On top of the “TO DO” list was “low weight”: we introduced a new, extremely efficient and form stable internal structure. The diagonal fingers are split into narrow stripes with additional tapes. The internal camera views make you feel like being in an old huge cathedral: wide open, weightless bows: check it out!
Finally the big size of the RONDO (certified up to 240kg) is still below 7kg!

RONDO Designer’s Note

As we began with the new biplace project, we wanted to do something outstanding, that will set the margin for the next years.
The whole development of the RONDO took as a long time, but we wanted to be as careful as possible. We even already made a certification load test in advance to be able to have pre serial wings been tested out there in the wild.

We integrated the feedback of the pro pilots into another step of evolution. We experienced that we have found a super efficient solution to the “deep spiral” problem, many biplace wings have. The challenge is, offering super high agility and no stable deep spiral (which leads to a fail in certification tests). So the RONDO is offering an extreme good handling, still being easy in the spiral.

We made lots of takeoff test with video analysis to be sure to have best inflating wing in that class. Now the RONDO is not only inflating extremely fast: it is rising up perfectly, and because of the superb performance: lifting you off the ground easily.
