I am wholly unqualified to comment on how a pilot license/certificate from one country translates to another governing body's regs. But, to specifically answer your question about an FAA Flight Review, this is an excerpt from Part 61.56:
(1) Accomplished a flight review given in an aircraft for which that pilot is rated by an authorized instructor and
In other words, if you're a plank pilot, you can do the review in a plank. Because I don't fly as a pro, and the R22 is all that is available to me for renting (SFH), and the regs require me to have an annual flight review in the R22 to fly the R22, I do the flight review in the rotary machine, and that also covers me for stuck-wing flight.
Now, that may or may not please the insurance company.
You may need the review in a heli to be insured in a heli, and maybe in a particular model. Too, a review in an airplane won't show up any rotary-specific flying faults you have, so you may be legal, but not necessarily safe.
