R66 fuel burn - usual gph

01-12-2016 10:38:36

I have been a R66 owner for some 6 months. But I have never obtained the 22 gph quoted by Robinson. At 70% torque and lightly loaded, I obtain 23 gph. At 80% torque and lightly loaded around 24 gph. The other day, when fully loaded at 80% torque it was up to 25.5 gph. Is this normal? Is there any type of adjustment to the engine that I need to consider? Antosh

Well I own oo61 since new in early 2012. I mostly do fly around Guatemala City which is 5,000 ft elevation. So mostly I fly from 5,500 to 9,000 ft ASL. I consistently get 18 gph and sometimes even 17.
So probably Robinson was averaging when quoting consumption.

At what % of torque do you get that?

Are you talking US Gallons or imperial? Seems on the low side at 17-18GPH.
Owned a Jet Ranger for 4 years and it was 25US GPH.

I have owned a 66 for 5 years and consistently get 85 likes (22.5 US G) per hour, thats heavy and at sea level (very flat in Oz) always pulling about 75%

That should be litres per hour
