If you are thinking about a possible career in the future... I'd learn on the R22 first
Rather bizarrely, I was given exactly the opposite advice; if I had any inkling that I might wish to pursue a commercial licence, learn on the S300 (no governer, proper cyclic) and get an R22 rating later.
After all, what self respecting female would be caught dating a robbie driver!
Reminds me of spoof lonely hearts ad my so-called mates put in the paper on my behalf:
"Wanted: helicopter pilot for nights of passion. Send picture of helicopter"
Ground effect - it's a fair point, well made
Cheers
