Valuable experience

1. If you have the simulator, we recommend you to practice with the FMS before you try the Diamond Glider.
This will be very helpful for your real flight.
2. Check and make sure all the control surfaces work normally and move towards right direction before
flying.
3. We recommend you make the glider climb up to 100m height and hover with 30% power. This will be
helpful for you to get familiar with the performance.
4. Users should control the airplane genteelly to reduce the risk of crash, and to prolong the working time of
the airplane.
5. The turning radius should not be too short or the airplane will be out of control more easily and this may
cause more crash incidents.
6. This airplane is not suitable for flying in low attitude with full speed or for nose-diving.
7. It is normal the aileron servo works in low efficiency when the airplane flies with full speed.
8. Please make sure to take off and land against the wind. The beginners had better fly in breeze and up
wing area.
9. Please fly your Diamond Glider in the upper front of your head, but not above your head as this will
increase the difficulty.
10.If you want to fly it for a long time, please buy more batteries from the dealer.
