It helps a great deal, especially in being able to fly at yourself. It will not help much with landings.
The plane flies nice, slow, and gentle, and... to you, it will seem way to fast, overly sensitive and out of control the first couple of flights.

Then, after a little stick time with an instructor, you will realize you actually have some input into where it is going.
LOL, don't let the adrenalin get too out of control, or let your legs shake too badly. The shaking is the giveaway of a beginner. Something you will never forget. I think most of us have a wonderful memory of our first flights. Oh, and don't get to far from a potty. Hehe.
Be sure to post your impressions after those first flights.
