Hi there,
They work just like your full size chute does. They steer by pulling there arms down to pull on the steering lines. To pop the chute we have an extra servo so you can freefall as far as you want. (just like full size, you have to pop the chute with room to spare)
As far as swooping, our chutes are more base jump style or general design. We do not have the small chutes that it would take to get that much speed up. Check out our website. The shopping cart has alot of information on what you get and what is needed to complete the skydivers..
