Background from (http://freedom2000.free.fr)
The Nasa Para Wing (NPW) kites are extremely popular and it’s not hard to understand why.
The flying window is a bit smaller, partly because the NPW’s need a certain angle of attack to stay inflated properly but also because they weigh so little that there is no momentum in the kite that helps to expand its flying window when in flight. But the great advantage of the ultra low weight is that they fly in virtually no wind. So even if you prefer flying advanced foils/LEI’s/hybrids, this aspect should make you want at least one (preferably big) in your quiver of kites: It will fly when all other power kites refuse to leave the ground!
- First of all, they are cheap to buy and offer a cost-effective way into many power kite sports.
- Second, you can easily play quad line kite compare to revkites
- Third, they pack down small and weigh very little so it’s easy to always have one with you.
- Fourth, the time required for setting up to fly is minimal – a minute or two is enough!
- Fifth, they are easy to launch, land and relaunch without assistance, regardless of size.
- Sixth, they have a massive pull relative to their size.
- Seventh, they are virtually unbreakable (but please remember that you are not!).
- Eighth, because of their excellent low wind properties, they have a wide wind range.
How does it perform?
Its main advantage is that it pulls very evenly, regardless of flying direction, and is very smooth and controllable in its behaviour. The flying window is about 135° sideways and is largely a compromise between good behaviour and big window. Pushing it another 5-10° is possible but results in the kite becoming nervous, twitchy and generally unpleasant.
The Nasa has an incredibly strong pull which is more evenly distributed across the flying window and holds up better through tight turns. The sail also holds its inflated shape better in sudden gusts than the flatter Buzzard Vnose.
The quick and precise response makes the Nasa very well suited for big sizes. In comparison, the Buzzard NPW9b’s feel slower in reaction, more “floaty” and less powerful.
Now go ahead and make one! You will not regret it.
How do I fly it?
The Nasa, along with all NPW’s, needs some tension on the brake lines to keep it properly inflated. Eliminating this character in the design of the kite is easy to do, but results in a kite that does not perform at its best. Flying with some tension on the brakes is easy to learn.
How and when the collapse begins differs between various NPW models, however. The Nasa is easy to fly in this respect as it is very stable, has a soft way of collapsing (by nose deformation rather than a violent collapse with total loss of power) and never really does anything unexpected.
To turn, you either pull in the brake on one side, which causes a sharp turn. Alternatively, pull on the entire side (power and brake line) for a more gentle turn. Doing one at the left side and the other at the right side causes it to fly sideways! Pulling in both brake lines makes it fly backwards. Like all NPW’s, it is preferably flown with handles, but big ones can also be controlled with a bar (brake lines connected to bar ends). All four flying lines should be equally long.
The “depower” (not true depower because the angle of attack of an NPW can’t be varied) of the Nasa works as follows: Flying speed controls the amount of pull. Slowing the kite down by pulling in both brake lines makes it pull less. If you become seriously overpowered, pull hard on the brakes until the kite collapses and flutters around with very little pull, rather than putting yourself in danger. If that is not enough, let go of one handle to make it pull even less.
When the wind is strong, launch and land at an angle instead of straight downwind to reduce the risk of getting overpowered. When landing it can easily be backed down with the trailing edge first (preferably to the side if the wind is strong) or simply flown into the ground nose first. Nothing will break. If it has landed on its nose, it can be restarted backwards by pulling on the brakes until it backs up.
The Nasa can be flown on two lines instead of four, but there is little to gain from this except that it’s easier to learn how to fly a kite with two lines. What you loose is the ability to control speed, do sharp turns, reverse starts, safety collapses and much more. I have so far not provided the brake line lengths for a two-line setup. These are, however, easily found by experimentation.
When packing away, the flying lines can simply be rolled up on the handles, all the way up to the kite. When preparing to fly next time, simply lay the kite on the ground and let the lines roll off the handles while you walk away from the kite. With a little practice, this can be done with zero tangles and twists in the lines and the time required for packing up and away is reduced to a few minutes.
What size should I choose?
If you have little or no flying experience with NPW type of kites, the default size of 3.7 square meters is a good choice for your first Nasa. It is big enough to fly in very light wind and perfectly manageable in moderate winds. Smaller sizes are faster and bigger ones pull more, both of which can be more demanding on the flyer. Remember that this kite is not suitable for children! Always fly with care – a modest 3.7 sqm NPW can get you seriously injured or even killed in stronger winds!
