I'm experimenting. I've got my Stunt throttle curve set at 85% across the board, and my Stunt Pitch curve is linear. I guess what I'm looking for is stability (lower head speed), but full control over pitch. What are some good pitch curves to use?

If this your blade 400 you are asking about, I have found that running linear from 85 and above always works the best for me. I run a older motor, so I am kinda forced to run 100, 100, 100, 100, 100.

I have also noticed only 5% increases shows a difference. So If I go from 85 across the board to 87, no differenced is noticed on my end. But when I adjust from 85 to 90 across the board, I do see differences.

If your not doing any hard snappy 3D manouvers, I se no reason to adjust the actual pitch of your blades at the top and bottom of NO MORE then 9 degrees. This will also help your management of prolonged flights, with a snappy feeling, all around.

may i ask why you are looking for stability at lower headspeed? i always run throttle curve @ 100%.

I would say he is looking for longer flight times, with exact stability/manouvers, while having the lowest HS.
I think This is a miss conception, as a efficient set up runs at a proper HS, weather it be high or low.

more efficient + lower headspeed = smaller pinion gear + 90-100% throttle "curve". speed control most efficient between 90-100. if you wanna lower headspeed, drop down a tooth on the pinion. should give you what your lookin for.

To be honest I like the way the heli flys in normal mode, but I don't like the motor speeding up and slowing down as I adjust pitch. When I fly stunt mode stock setup, the heli is very twitchy. I know it comes with a 450 size heli, but I still like the slower flight charactistics of normal mode.

ok, now i understand. your best bet then is to drop a tooth on the pinion gear, and set your speed controller to higher values. that will give you the efficiency of being 90%+, and the slower flight characteristics you want. best of both worlds with 1 part change.
