You think you hands are shaking now??? Wait till you have to explain to your wife/girlfriend/husband/spouse/parents that you just dropped $5,000 on a new plane and engine!!!!!
Welcome to the hobby. In all honesty, it sounds like your shakes are from normal nerves as you learn to fly. If you don't have an instructor you may want to find one as they will be able to help calm you down some as they can prevent a crash. But the shakes and nerves to get better as your skills improve. Hang in there!!!!
