I can't believe that I'm about to write, what I am about to write but, these are extenuating circumstances!
We have someone with an Exec who lives round our parts. I don't know what the normal flight rpm is supposed to be for this heli but you can hear this chap's engine from miles away, screaming and humming across the distance and seeming to linger in the air (the noise that is) forever. Even as a heli-aficionado I find it objectionable!
To be honest I would rather you buy a Robbie - OMG I've actually said it
may God forgive me!
Rotorways for sale here
Same priced Robbie for sale here
And if you had the budget, this is what you should really buy
Happy flying.
