It really depends on what is your FW flying background, over here we have a situation in which 90% of airline pilots went straight from their 180 Piper/Cessna hours into the cockpits of airliners. They have been flying by pushing buttons to go up, down or where ever, the little hand flying they have done has been in a easy to fly, stable acft. and their biggest handicap is that they want a checklist for everything, they need someone to tell them which way to land and where the wind is from, their decision making criteria is very unexercised.
And now they want to climb onto a helicopter, and sure teaching them to learn to manipulate the controls is difficult but not impossible, they eventually learn to solo and land by themselves, but the really hard part comes when you try to make them understand their enviorement, limitations, capabilities and the need for them to make serious operational decisions based on those factors. Their "old fashioned" airmanship skills are really low and they just choose to hover around the airport on nice days, and stay out of any spot that becomes a challenge.
But if your previous FW experience is more like Crop Duster then I am sure it will be an easy task.
