I recently went to a spot where I could only lock onto 4 sats and not being familiar with Naza mode and lots of trees around, I ditched the idea. Now I would really like to go back to the spot and try again, but I need to know what to expect after takeoff. The spot is in a deep but narrow valley with tall trees around, that's probably why I can't get more satellites. Although I will be flying up so I expect that more will lock in within 3 minutes or so. Advice is much appreciated.
