Dynamic Soaring is both amazing and counter-intuitive
for slope soarers.
Twelve years on from these clips the World Record in the
USA is now over 500mph! (no typo) It needs the right kind of hill to do it and
considerable flying skill. I have tried it successfully
but beware, one can wreck models quite easily.
Here are two video clips (14Mb and
20Mb) of my brother, David Woods, Dynamic Soaring some years
ago, note the jerky 15fps footage - he was demonstrating
the technique on a pleasant weekday on the empty hill. The wind is on the
North face of the hill, about 10mph, and the DS-ing
takes place on the opposite facing side on the ridge. Turn the
sound down. Ds-ing at Ivinghoe is now not
allowed. |
