Another one of those "personal preference" sort of things, but I like 1850.

The government cannot give you anything without first taking it from someone else.

FenderBean,
Century fliers of the Falcon/Ravens are running headspeeds anywhere from 1800 to 2000 for 3D. Of course maintaining that rpm at full collective will require tweaking of the max pitch depending on how much power you have to work with. Meaning you may only be able to carry that speed with +/-9 degrees with a 46, whereas any 50 should handle +/-10, and the Hyper 50 pretty much whatever you want and still need a governor to tame it.

You said Falcon 46, is this an older falcon?

FenderBean,

Don't know if you are using a tach or a governor, but my opinion is 1850 gives the power needed in the rotor for 3D flying while not overstressing the system. Kind of a "middle of the road" sort of thing. I know a lot of the hard core 3D guys run a lot more, but i'm not that agressive a pilot. Additionally, I watched Curtis Youngblood fly at the Corpus Christ funfly a while back, and he did his entire flight at 1850. Now I'm by no stretch of the imagination anything like Curis Youngblood, but I figure if it's good enough for Curtis...........

I use 1500~1550 on normal and 1800~1850 on idle-up.

I would not recommend speeds over 1900 rpm, though I know people that fly on the 2000+ range. To me that's crazy...

If you are going to speed up your rotor be prepared for a very fast and twitchy cyclic. Also you may want to reinforce the angel screws.

The thrust bearings inside the grips are not bullet proof either...

It's easy to find an excuse to do wrong. Hard is not to find an excuse to do right.

I try to be right at 1675 when hovering and flying around slower in normal mode, 1700 is the max for me in normal mode, I find hovering at 1650 or lower my Falcon just will not respond to the cyclic as I like it too and she is not as stable as she is at 1675/1700,,

in idle-up 1 all I do is loop and roll so I try for 1750 to 1775 because with the Hyper and Weston tuned-pipe I have quite enough power, in idle-up 2 I try for 1850...

""2000+ range. To me that's crazy"",,, me too..

note, my Falcon is now a Raven and I have only 1 hovering flight on it, as a Raven I may find my needs to be different..

yeah i tried 1850 its perfect, i have a 50 engine on the way since my 46 is damaged, so i may be able to drop down to 1800 or 1750 if its strong enough.............i had it up to 1920 just checking it wayyyyyy to much rotor speed
