Hi guys, I don't know why, but I keep getting strange ideas to try a helicopter , (even though they are inherently unsafe as the wing travels faster than the fuselage!!

)

, I already have a PPL (A) , and have just over 75 hours. \if I want to do my PPL(H), how much previous flight time can I use as credit, and how much is it going to cost roughly?
I take it there will be a few more exams as well, A/C heli general and Flight performance and planning, anything else?
Also, can anyone reccomend a good place for time to cash value for a helicopter trial lesson please, in the West Midlands or Swindon area?

cheers
