Busy making money so I can buy the groceries..... vhpy

John is right..........6500 rpm continuous
and
6800 rpm max for 3 mins (normally on take-off, if required)
Airspeed, altitude, or brains....you always need at least two

Greg is busy with a serious project which is demanding a lot of his time. Note that he does keep an eye on the forum behind the scenes though. His infinite wisdom is however missed in so many avenues. I don't want to speak on his behalf though.....

In short, we DO MISS HIS PRESENCE, POSTS & PARTICIPATION!
