Well lots of good info,
I get this way exspecly when I fly at a new site.
1. Always fly my cheap and easy Rifle 1M, its fast and cheap and helps me get a feel of the area.
2. Always get a spoter, one that is cable of flying my jet if needed.
3. I do get realy nervous some times and my leg shakes, and I try to control my breathing like I do when I run, and it helps me calm down.
4. DONT give up, I have been nervous and felt all kinds of odd, and thought I was going to crash, I gave up in my head, then snaped out in time to save my jet.
But I guess practice is it, I have only been flying for 4.5 years so I need more practice I guess.
