I like my first flight in a while. 4 or 5 minutes flights, don't mean a thing to me, well unless I go inverted for a bit but even then it's just a quick "Whoa Nelley" and then were back to stable. But that first flight, I land regardless of what I was doing and I'm great, till I lean over to put the handle down and stand back up. Then I can't walk a straight line for NOTHING. The next flight and we're back in shape. You were 17 when I was born so, I have noticed it getting worse the older I get. best bet is to keep flying I guess. Oh, and I got dehydrated about 10 years ago and I had at least one of those crystals that are on the hairs in your inner ear you use to balance came loose. Man, 1st 6 months it was kinda iffy for me to lay down. The bed would start spinning so hard I'd fly off. They give you these exercises to take care of it but what it really does I think is teach you how to ignore the messed up ear and do your balance from the other one. It still gets me from time to time, I'll turn a corner and wow I'm drunk for a second or two.
And it is flying for the pilot alone. However, if you've ever been up with another person. Not necesarily racing or combat but just flying around with another. Well that's flying together like my RC guys don't quite understand. My biggest group fly was 26 people. We had a big orbit around the center for a demonstration group fly. That was nuts and fun.
