Parasite Drag,
I think that when Troch says he wants to "hours build", he is not refering to how long it will take to construct a working, flyable helicopter.
In the case of a Rotorway that will be a lot of hours indeed.
(there's another thread for this, so nuff said).
As for Hughes 300 being as good, or better than a R22 I'll moderate what I said previously to:
"If you are under 14 stone, and/or under the age of 50 and/or less than 6ft tall, and the running costs of he helicopter are of paramount importance, then the R22 is the only aircraft to consider."
If you are of a bigger build, or coming to flying later in life, then the Hughes 300 and Enstrom 280 are excellent machines, especially for training, low-houred pilots and aerobatics.
But they will always cost more than a R22 to run."
