My knees quit shaking some years ago when flying, even on maidens. I miss that feeling but can't seem to get it back even with big planes or long builds.
Wish I could, it's like something is missing.
Maybe you need to spend more money on your planes?

Have you tried a turbine jet? I imagine if that doesn't get your knees shaking you should be flying for the USAF.
But what the hey do I know, I only solo's 'a couple of weeks ago'.
