Re: LEI power comparison with closed cell foil.

But thanks so much for all the feedback everyone! MUCH appreciated :) I'll definitely try LEI out :) You're welcome Rannoch. Feel free to ask more questions.

Re: LEI power comparison with closed cell foil.

Thanks for the multiple invitations to post on this topic :pump: In answer to your questions: Inflatables are vastly superior to ram airs.

Re: Tube Kite To Foil Kite- Making the Transition

Here are some more points to consider before making the transition: LIFT TO DRAG RATIO (L/D) [/b]Rams have significant drag ("D") for 3 reasons: a) Increased friction at the "boundary layer"; ie interface between air & kite, because of minute ripples in ram air kites. b) Bridle drag. c) Thickness. ...

Predictions for Ram Airs in 2019

Well, it's that time of year again. 2019 has arrived with a bang or, for ram lovers, another big swim-in with their sleeping bag. Previous predictions about ram airs have proven amazingly accurate. The exodus of riders from ram to inflatable will continue; ram air sales will continue to fall as a pr...

After his canopy went down, he was too tied-up to free himself or save his flying sleeping bag. Check-out how his friends are struggling to drag the waterlogged bag. Ram...

Re: Will we see the first foil kite at King of the Air 2019?

I guess we see what we wanna see... Then I see what looks like a foilkite going to 5th line safety with instant powerloss. Ram airs are DANGEROUS!! Even if what we're seeing here is a deliberate flag-out on the 5th line (rather than a completely uncontrolled ram air collapse), it begs the question:...

Check out the ram air kite collapsing and deforming between 28s -> 34s. This could've easily ended in tears, injuring the rider and/or the...
