I Must agree with 407 DRIVER,
we aslo run a 206 for general charter which serves its purpose well and i have just come out of an endorsement on the 407 with only about 6 hrs so far on it but its an incredible performer, the one we have in our hangar is owned privately as well, but its a clean skin acft with no S&*t hanging off it and at sea level we cruise around 125-130 at 76-78% tQ.
Fuel Load with the Aux tank is 559lt or about 900lbs and burns around 300lb an hour.
you cannot replace your 206 for ease of maintenace and reliability but its horses for courses, the 206 serves its market well, upgrade to the 407,130 or 350B3 and be prepared to part with alot of the folding stuff to cover cost, especially if a LCD guage dies!!!
Having said that....the 407 is a real performer you wont be dissapointed, only quarm i have is the cabin layout, not much different from the L4 i prefer the open cabin in the 350's but hey beggers cant be choosers!!
