I have seen many videos on youtube in gameplay with the F-104 taking off in full power and nice attitude
That should be enough to understand the problem as I've said, never happened to anyone else before.
I don't know what is the problem.Thank you.
If I knew what the problem on your system which is affecting the F104 in a way that nobody else reported before, I would already told you a solution. The one already mentioned are the only ones I can think of. Sorry, but it's nothing related to the product, otherwise we would have hundreds of reports by now, considering the F104 was released in 2005.
