The Panic Button
When you’re learning acro mode and new freestyle tricks, or occasionally when racing, it’s all too easy to get disoriented and start heading for trouble. Wouldn’t it be great to have a “panic” button that would immediately set your quad upright, then let you get back to flying? Today we’re going to set up a momentary switch on the radio to do that.
A momentary switch is one that won’t hold its position; it will reset itself when you let go instead of staying in place. Most hobby-grade radios have one in an easy-to-reach location, which is perfect for this purpose. We’re going to make it so that as long as you are holding this switch, your quad will use auto-level mode. If you’re already flying in an auto-level mode like ANGLE, the switch won’t do anything—but if you’re flying in acro/rate mode, it provides immediate (but temporary) access to the auto-level feature. This can be very valuable when you’re still getting comfortable learning to fly in acro.
