The last two flights today out of 4 flights total my landing gear would not come down! I had to bring it down to a level I could hold onto the drone's feet as another person hit the power button on the ST16 controller. Both times the moment I powered off/on the drone reset with the feet coming down to the landed position no problem. Any ideas? While it was a preorder H before came out this drone has been barely used --Maybe 20 hours flying time tops.
