Do not charge the craft battery unless you will fly the same day. After the batteries are charged, remove them from the charger and place in fire-proof container until use.
Download the Operation Manual from a Yuneec website and take time to read and study it. Your first flights should be in an open area. To avoid dust and debris, use a landing pad or a clean, level spot to take off from and land. Always turn on the ST16 before the craft, and always turn craft off first at end of flight.
Typhoon H systems are shipped with the ST16 and craft already bound together. Before flying, remove props and perform Compass, Accelerometer, and Gimbal calibrations per the Manual instructions. The Compass calibration may require several tries to get correct, and if it continues to fail move to a different spot clear of metal or magnetic interference and retry. Many owners remove the camera first to avoid possible damage; others recommend it should be left on.
Accelerometer and Gimbal can be calibrated indoors on a level surface. Although Manual 1.2 mentions flying to calibrate the Accelerometer, it is best for new pilots to leave it stationary on a level surface.
Always handle the camera with care, being in an exposed bottom position it is subject to damage, or one or more of the 4 rubber shock supports may pull loose (an easy fix). Push up on the release lever and carefully pull the camera forward to slide it free to remove it from the craft. When you do have one or more rubber shocks pull loose, look here to fix it.
Go ahead and fly your new Typhoon H awhile to ensure correct operation and to familiarize yourself with flying the craft before performing any firmware updates. Fly in Angle Mode with GPS ON (default is ON), and only use slow speed (Turtle) to take off and land.
Place the craft facing away from you. Allow time for the craft to collect enough GPS satellites for a good position fix (the first flight of any day will require more time). Usually this will be more than 14, and the craft rear light will turn solid purple. The ST16 also collects GPS Satellites so that the craft will know where the controller is during the flight, even when the controller moves. As the ST16 collects 10 or more, the craft will add a white flash on top of the solid purple. Now you're good to fly. Your ST16 screen should resemble this: Typhoon-H-Startup-Screen
After you push the red button in Angle Mode to start the props spinning, a Green Arrow will appear onscreen. If the craft and controller are close together horizontally, the Green Arrow may point here and there, but after you fly the craft away, the Green Arrow will ALWAYS POINT in the direction you need to move the right stick to fly the craft back toward you. Here is the Green Arrow on screen: Typhoon-H-Screen-Green Arrow
Also when the props start, the indicated height is zeroed. Height is Barometer controlled, and may vary from actual height by several feet, especially with falling or rising barometric pressure.
Anytime you lose track of the craft, use the Green Arrow or the Return To Home Mode to fly back. But you must have GPS locks on both ST16 and craft and must be in Angle Mode. Always fly high enough to avoid trees, power lines, and structures.
Keep a watch on the craft battery voltage, when it drops below 14.8 volts, make sure the craft is not too far away. First low voltage warning is at 14.3, so plan to land before then. Never let flying voltage go below 14.0 (no-load voltage will be several tenths higher). While airborne, do not take the craft or the ST16 under obstructions that might cause them to lose GPS Satellites. Height is your friend, both in GPS coverage and in craft control and video signals.
Taking off is relatively easy, but landing needs close attention. First center the craft a foot or two above the landing spot, then using only the left stick, hold it all the way back and land, taking care to keep the stick centered. If you unknowingly have the stick slightly to the left or right the craft may bounce and turn over. See THIS video for landing info.
WARNING: Do not change or tamper with the Channel Settings unless instructed by a Yuneec Tech. Pay no attention to internet advice to change these settings. A Typhoon H that is or becomes erratic, hard to control in Angle Mode with GPS active, may have Compass and/or GPS problems. If several Compass re-calibrations and good (open area) GPS satellite acquisition do not correct this, contact Yuneec Customer Service and ask to speak with a technician.
