Test with the Ehang has been unbelievable. Even though there is lots of vibrations in the gimbal, i would think that the controls and the drone flying is unbeatable. So far the drone has landed hard on a few occasions but the blades are still intact. The gimbal has been really giving lots of problems, I'll be getting it repaired soon. Best way to test the Ehang customer service is to actually get my own drone serviced right? We hope to get more customers onboard the Ehang Ghost Drone, its really easy to fly and there is no complicated remote required. The drone is almost capable to fly itself.
