Do I have to be careful not to hold the left stick down for 3 seconds or longer if I want to quicken my decent from a high altitude? In other words, does the drone consider current altitude before allowing the 3 second shut-down to be initiated? I sometimes want to descend as rapidly as possible to a lower altitude before then bringing it in slowly to land. Accidentally shutting off the props at high altitude would bring her down a little faster than I would like. Thanks.
