![]() ![]() In our tests, it was found that sometimes NCB’s fly OK for a while, especially if they are not carrying payload, but sooner or later a gust of wind comes along and then they go right down to the ground, with little self-righting capability. Spurious claims are sometimes made about Net Curtain Balloons (NCB’s) from certain suppliers, including ludicrously unrealistic wind speed capabilities (such as the ability to fly in hurricanes), absurd aerodynamic lift claims, incorrect line angle data and incorrect stability data. This is why thousands are sold worldwide for a very wide variety of tasks, many of which were not possible before the advent of Helikites." "Helikites fulfil peoples' expectations of lighter-than-air aerostats. Helikites cope with extremes of temperature, wind, precipitation and maritime weather conditions better than any other aerostat in the world. Helikites are far smaller than most aerostats for better performance and are both simple and safe to use. Helikites have excellent pure helium lift, and solid payload attachment points for cameras, radios and sensors. ![]() Helikite flight is stable, high altitude, all-weather and reliable. If you wish to return the other blimps, (which, after flying them we think you will) then we will refund you the money. You can fly them in any weather you like to see for yourself. If you wish, we can provide you one of each type of aerostat design of the same size for fair comparison. What is to be done about this problem? Simple. The problem is that as Helikites are also small, rounded aerostats we may be tarred with the same brush and so customers may tend to think Helikites will behave the same way. Later they often find that in winds, dust-storms, rain or with added payload, their so-called aerostats are not flying properly, but instead they are crashing around all over the place. Some aerostat operators and government agencies spend tens of thousands of dollars on inferior net-curtain balloons, tethered balloons or small blimps that were only test flown in calm weather before purchase. We doubt their claims, as experience tells us that other designs of small aerostats often do not fly very well in adverse weather. However, customers may find other aerostat manufacturers claiming their aerostats are good too. We are very confident that Helikites are far better than other comparably sized aerostat and tethered balloon designs. Tethered balloons, aerostats, Helikites and blimps all behave differently when flown. ![]()
