just asking for some ideas here...

Is there such a standard setup? (i bet is user preference)

for Normal pitch settings
and the so called 3D setting curves?

here is my issue. I want to get used to flying Normal mode
hovering at 3/4 stick, so when I change to 3D idle up, flying around at 3/4 stick wont feel weird.

Flying idle up mode +10 0 -10 I have no problem.
but when in Normal mode, if i set curve to hover at 3/4 stick
then half stick and below feels like allot of dead space
because in Normal pitch curve I have -3 at full down stick.

I know the cause of the dead area is, Its because of -3 instead of -10 at bottom stick.

When using normal (hover @ 1/2 stick) I hate transitioning to idle up by compensating with more collective. I havent found a smooth consistent way of me doing this.

Are people just living with this (dealing with the jump or gap)

by the way I have a 9C futaba.

thanks!
Joe

Most people are setting up the heli to hover at 3/4 stick in "Normal", as it eliminates the jump. I am one of the holdouts for the old way of hovering at 1/2 stick and the way I get around the jump is to always switch into Hi Idle #2, the only one I use 3/4 stick and 1/4 stick hovering, is to always switch at full stick, where it is the same. I know it's weird, but that's the way I chose to do it.

Thanks, I agree...


I guess Since I dont have a 1000.00 radio 9Z or 10X radio, I will have to deal with it.. My only gripe is in normal mode midstick to low stick resolution. Ex:


Normal Mode:

stick high: +9
3/4 stick +5 (hover)
half stick 0
Low stick -3.5


See. from midstick to low stick theres alot of stick movement compared to top half..

That's exactly why I use the old method of hovering at 1/2 stick.
Normal: +9 deg full
+5 deg 1/2
-3 deg back stick

Hi Idle #1: +9 deg full stick
+5 deg 1/2
-5 deg back stick

Hi Idle #2: +9 deg full stick
+5 deg 3/4
0 deg 1/2
-5 deg 1/4
-9 deg back stick

Hold is identical to Hi Idle 1

Hope this helps.

the defacto standard for most pilots in the US flying 3d

is to have all the pitch curves the same.

normal
idle 1
idle 2
hold

now what yer heli/motor will pull determines what the curve is, but approx -10 0 10 is a good place to start.

I read that somewhere...

but darn -10 on normal mode bottom stick?
I have never tried that... but your right, that should resolve that!


I see this applies to Th. hold as well?
doing autos with -10 on bottom stick doesnt sound healthy...

what is one to do, limit down stick to somewhere approx -3 -4? on Th.
hold curve that has -10 on full down stick?


thanks guys...

ya learn to fly the stick, not the stops.

and ifn ya wana do any aerobatic autos at all, ya need -10 available to pull some of it off.

besides which, do ya really wana learn to fly a "diferent" heli fer each mode?

No i dont want to learn different flight modes! Your right! Thats why i posted this question originaly...


hey guys speaking of autos, Do you guys use +10 for autos, I assume so since all curves are the same...

Im talking regular old school autos not those 3D autos

i don't recall ever hitting +10 in a regular auto, -10 either.
i have hit the stops in aerobatic autos.

thats cause your effissient with the collective (you know your stuff)
for the beginers I hit the top stop with the collective!

One last question.... running same curves: normal flight mode will be -10 0 +10, how are you guys setting your Normal Thr curve?


thanks

Here is what I do,

I have all modes set to -10/+10 pitch. Then for normal mode I put the pitch gauge on and find the low pitch setting that I want, say -4. At this spot on the radio I set a point in my pitch curve. Then I go to full low stick and bring that up to the same setting.

Example: Say my pitch curve goes from -10 to +10 at 0-100 on my stick movement. At say 35 on my stick the pitch is about -4 degrees which is what I want to limit low pitch to in normal mode, I set a point in the radio at that level (35). I drop the stick to full negative and bring the low end point up to 35 so that from low stick to 35 I have a flat line. To verify that you have the same setup in all modes just switch between your flight modes while you have the pitch curve displayed, the line from 35-100 should not move at all between the different modes, the only change you should see is the flat line from 0-35 when in normal.

What this does for me is to give me the same feel for the collective from 35-100 as the other modes have and it limits the low pitch in normal mode to something reasonable for spool down.

Throttle curves are basic v curves in idle 1/2, I use a GV-1 to control the RPM.

Hope this makes sense.
