PHI RONDO

Technical data

RONDO and RONDO C share the same tech data. The RONDO C version is ~100g lighter due to its use of lighter unsheathed lines.

Colours

Standard colours: CC01 (Deep Blue, White), CC02 (Orange, White), CC03 (Dark Red, Royal Blue), CC04 (Sun, Royal Blue).

The bottom sail is mainly white.

RONDO: SHARED JOY IS DOUBLED!

Performance shared is performance doubled! As most biplace wings on the market are low B concepts, PHI heard of the demand for a high performance wing, that is stylish and a joy to fly with.

Designer’s notes

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.

Technical Features

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

But beyond that, PHI 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 behaviour 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 “TODO” list was “low weight”: PHI 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!

Take off

PHI spent a lot of time to optimise the takeoff behaviour of the RONDO.
-how it gets inflated, how it comes over the pilot and how it lifts you off the ground were in our focus.

Finally, because of the NITINOL rods the inflation is perfect. In stronger winds you may only grab center As to have it a little delayed.

The rising is optimised: PHI were working on double B position and fork geometry.
-and finally (because of the superb performance): you get lifted extremely early.

Feedback from all test pilots: you are impressively picked off the ground after a short run.

Landing

For a super nice flare, you need a brake with good reaction and feedback, which is producing just the right amount of lift.
-and you need a wing with performance to have enough energy.

You will love the flare behaviour of the RONDO!

Nose Padding
