...Ti was on for that one - only one green light when I activated it. I only ever get one green light, the Ti sensors seem to be working, although a bit bent, when I wave my hand in front of them I get both greens....
Well, the reason you had one LED is because of those trees in the back yard. That area is too confined for good Ti. I had that happen in an area 100 yards in every direction but it was encircled by trees. I guess they trapped a certain temperature in that circle which confuses Ti's calibration. It will fly better once you clear the tree tops but you will have to adjust the trims again once up there because it was calibrated at ground level.
