Mine takes off fine. I barely need to add any "nose up" trim and it takes off.

Also. Load the B-52 Cleared for takeoff (KNKX) flight and see how you go with that. Once the flight is loaded, you can move the B-52 to any airport you like. ;)

Note: B-52 Cleared for takeoff (KNKX) might actually show up in the list as Â-52 Cleared for takeoff (KNKX). I do believe I renamed of mine! ;)
