Ok, so the 66 is a lot lighter! That's going to save all those good things like power required, etc. That answers why they can get away with a smaller engine than a JR.
Soave, or Arrrj what is the fuel capacity of the 66, just curious regarding the 3/4 fuel comment, as I have a lot of discussion with 500 pilots who love to tell me that on full tanks a 500 will out lift a JR. My answer has always been fine, but if you are stuck 400 miles offshore on a sinking boat, I would rather have a JR with full tanks than a 500, as I can't swim 100 miles, maybe you can. Or, you know, bigger tanks, the thing is going to lift less when the tanks are full. It's the stupidest comparison you could have.
So is 3/4 fuel an hours worth, or nearly 3 hours worth? If it's got tanks like a JR then that is quite impressive. I still won't get one, but pretty good for a Robbie...
I think that RR are learning something from RHC. how to really make money!
