A complex maneuver which can't be split into smaller easier pieces is impossible to master for me. The first step: just fly the kite from left side of the wind window to the right when facing upwind . The problem: on the other side of the wind window the bar is rotated 180 degrees so that piloting t...

...I'm thinking of just using a router with v shaped bit to take some material away where it's not really needed. Anyone do this? Did it on 2 LF fuselages. For the first one I have used circular saw, and the result was shaped with sloppy and uneven cuts, but still perfectly rideable. For the second...

I venture a guess that the only reason Ozone publishes the kite specs is that they are IKO certified provider. There is no specs by any other major kite vendor.

Now that we have athletes competing on tube kites, I would be interested to know how the performance numbers of this age group are compared to the top. Yes, there are 2 factors here, the age and equipment limitation, but how much does it affect VMG, is it only couple of knots?

Personally, I think the open slots are just a gimmik and it's only another 5-10 seconds a hole I spend on those bolts anyway. After you have experienced an improved feature it is hard to go back. For example, would you consider buying non 1 pump kite? I have made open slots on 2 carbon masts, where...

From the article: " In 1897, British engineer Frederick W. Lanchester conceptualized wing end-plates to reduce the impact of wingtip vortices... " 1897 was before the Wright brothers, when every attempted flight was going to the ground almost immediately after takeoff. The conventional wisdom at the...

Winglets is a known way to reduce drag by reducing the tip vortex. Not sure, havent checked, but I believe they are designed to work best and match the cruising speed, in order to save fuel, thus airline planes often use winglets. Neither Boeing 777, nor 787 have them, and widebody airliners are ar...

Are there winglets on stabilizers in commercial, general, or military aviation? Understandably, a foil with fancy shape of wings looks more expensive, but does it really have a positive contribution to the function?

…, but to return the planer to the cruising angle of attack when the flight is disturbed (by environment impact, pilot steering error, etc.). This works only for a stabilizer equipped with elevators, so it is actually not applicable for hydrofoils. The elevator’s function is only to offset the mome...
