RE: why should down mean up?
Welcome to the best hobby sport in the world. I can understand your rather 'strange feeling' as it's somthing many of us had to go through in our early days, but our desire to succeed saw us through.
Believe what the previous posters have told you and enjoy this hobby as we all do rather than trying to reinvent the wheel. As you travel along your learning curve and your flying skills improve this will simply fade away just like a bad dream.
