I can tell you that helicopters are as different to fixed wing as bikes are to cars.
There are a whole host of things which apply to rotary over and above everything which applies to fixed. The licence is different and requires many more hours. You will also need much deeper pockets for every aspect of rotary wing flying. If a small Cessna can be hired for £80/hour dry, you will probably be looking at something like £200/hour for a Robinson R22 or similar. Then there's the maintenance/service/insurance costs to account for, which are out of all proportion to fixed wing equivalents. It all adds up to making helos v.expensive toys to play with.
Now if you just fancy a couple of hours experience of flying a helo, then that is a different prospect altogether.
My only experience of actually flying a helo was over in FL - and a Bell 47 'Sioux' to boot. Brilliant!!!! The best fun I have ever had with my trousers on. You won't believe just how sensitive and responsive the controls are. I found it much more exhilarating than a Cessna, so the fun quotient is way higher - in my opinion. You pays your money and takes your choice.
If you want my opinion, you should take a day out and have a trip over to your local aerodrome and go and have a chat. I have done this in several places and always found the people to be exceedingly welcoming and happy to chat. I have never found anyone to be snobish in the slightest. On the contrary - they are like-minded people who like to have some fun. Talking with them will give you a much better idea of what you are thinking of getting into.
What you must do, is do something. I.e. don't prevaricate - get out and do the research and then get started. If you really do have 'the bug', then you will regret never doing anything in later life.
As soon as I have got my business up and running to a sustainable state, then I am doing exactly the same thing. See you up there!
