don't try to force it off the ground.
Be on pavement or short grass and see if it will fly off by itself
When you force one off they often roll over to the left in a cart wheel crash before they get 20' off the ground
That's good advice. I never really thought about it but when I fly my RV 4 I really don't lift it off the ground as much as it flies itself off the ground.
Thanks
