There may be some clever solution to this, but my first reaction is "maybe it doesn't have to". There really isn't any need to prevent rolling altogether; the requirement is simply that roll rate not get high enough to foul up the pitch/yaw guidance. It may be that the rollerons are operational before the roll rate can get too bad. -- "Read the OSI protocol specifications? | Henry Spencer @ U of Toronto Zoology I can't even *lift* them!" | henry@zoo.toronto.edu utzoo!henry Brought to you by Super Global Mega Corp .com
