Yes, every day is important! Even if you only have 15 minutes, it will help. One flight per day will help more than 4 hours of flying only on the weekends. Keep in mind that every heli is different, so once you get it right for one heli, try it with another. Eventually you get the instinct to take off straight during the lift off. It just takes practice.
Note: I say this because your real heli will likely be a little different from the sim, and a given amount of control input may not have the same effect, so you need to learn to adjust "on the fly"
