There was beautiful weather during weekend and I decided to perform the most important tests. They were related Manual Drone control thru LTE connection.

Saturday morning I did remove completely receiver from drone frame and I did setup Qground Control to support Virtual Joistick only.

In there theory everything should works fine. I did test LTE communication in-house several time and everytime it was fine. I took my copter and went outside to check hout it will work outside the home.

Virtual joysticks were enabled and ready flight and I was very curious their results.
When I pressed throttle copter flew up for a secound and then it fould down hitting ground. Everthing happened in just secound and I didn`t have a time to stop it.

My first manual drone control test using LTE failed. I need to analize it step by step now and to understand what happened. Is this something wrong with UAV configuration or software setup.
Summarizing I cannot fly using Virtual Joystick and I dont`t know why.I need to work more to enable this feature and to understand what happened saturday. :(
