If it's moving at "a quick pace" and in an out of control fashion... and I hate to beat this to death, but that was the responsibility of your so-called instructor to prevent that from happening.

Throttles are not on-off switches. You should be flying it, with an instructor, at no more than half to three-quarters throttle.. no more. Flying slowly to keep on top of things is very important for new student pilots. It makes such events as preventable rather than inevitable.
