I remember my first solo, a while back like!
The R22 gets quite twitchy, so as a previous post said just relax and keep that arm rested on your leg.
It will be very quick at getting off the ground! TIP:- Raise the lever so slowly and you can't go wrong!
Remember too it will be very nose up in the hover and on lifting, so put the cyclic forward a bit before you lift to reduce the chance of moving backwards, it's ok if you slide forwards remember!
After a while of solo flights you'll be able to "feel" the aircraft off the ground and bring it up nicely!
Last but not least, enjoy the experience!
