I am around 6ft 8" and a weight to suit!!!
I did some of my training in a Schwizer 300Cbi and then moved to a R44.
The 300Cbi is a fab heli room wize, i even fely as if there was enough room in it for comfort!!!!
The R44 was really nice to fly and after flying the "sky tractor" it was really easy!!!!
The one thing that enabled me to fly the two aircrafts was a did an Faa Ppl(H) in which you can fly multiple helis.
I think flying the 300Cbi has made me a better pilot as its so basic, and then as a result the R44 is so refined to fly.
Dont let your size put you off or stop you flying.....
