Great videos!

Never new about DS'ing and it was amazing to see how fast those planes were going without an engine.

I have been wanting to get a good soaring plane. I swear the winds have been a lot stronger ever since I got into a hobby that required calm winds (about a year now). If I have a soaring plane, maybe I'll be good in any wind.
I've made you the moderator for this section since I don't know enough about soaring/gliding yet.
Thanks for the post Michael!
