Throttle & Pitch Curves

[Hover_X]

OK, I've finally got this thing set up and have a question...

What is a good throttle & pitch curve combination for non-3D flight? I currently have the following:

Throttle: 50 - INH - 50 - INH - 100
Pitch: 40 - INH - 40 - INH - 100

With this setup, I hover at about 85% stick. Is this normal? Good?

I am trying to keep all my stick movement in the upper half so I won't have to re-train myself whenever I get to the 3D phase of things (if that ever happens at all:arggg:). That's why the flat line up to teh 50% stick position. With this setup I get about -5 degrees to about +12 degrees.

Thanks

why the heck are you starting your throttle at 50 man? How do you land and stop the blade from turning? Throttle is definitely suppose to start at zero. I also hover around the 80 area with linear throttle curve and 50-100 mid-high pitch curve. I'm going to experiment tomorrow with setting the pitch to 60 at mid stick and see if I get a little more stick range for the hover.

I use the throttle hold to start and stop the throttle so starting at 50 makes sense since when I go to 3D my throttle curve will be 100 - INH - 50 - INH - 100 and I won't have to learn new stick positions for standard flight.

hey, good answer heh. But I don't think 0 - 50 - 100 is much better than 50 - 50 - 100 in terms of learning new stick positions. Have you flown the gaui in 3D? If so, how do she hover inverted, still in the 85 range or even higher needed?

thanks

I was given the 100 - 50 - 100 recommendation from the place I bought the radio. They recommended this so I won't have to re-train myself once I get good enough for 3D. I just decided to bump the throttle down to the 50 - 50 - 100 which gives the same result, but doesn't spool the head up so much at bottom stick.

What settngs do you use? I'll give that a try.

As far as inverted, I don't do that! I have mastered the hover, but still have challenges with nose-in hovering and basic maneuvers.

Your throttle curve is "crazy" :lol:
(Could you imagine the throttle in your car doing the same, and you would control "take off" with the ignition key?)

I use 0-50-65-75-85 in normal, 85-75-65-75-85 in idle-1 (because the "upper half, have to match the normal TC) and 95-85-75-85-95 in idle-2

i use about the same as peter. it's all a matter of personal preference. experiment, and see what fits your style of flying. buzz flies with 100 straight across the board!:shock:

[mjr_larkin]

58 pitch at mid stick is a sweet spot so far. Really like getting in to the hover early, and no extra throttle required for lift.

Peter,

How does your heli start up with the 85-75-65-75-85 in idle-1 or 95-85-75-85-95 in idle-2? Isn't this the same result as mine starting at 50? Maybe I didn't specify that the curve I listed is my Idle 1 curve. I'm just trying to figure this out, so any info will help.

Do you use this setting for 3D or normal flight?

[rotorhead58d]

i always start in normal mode, then when i start to feel it getting light on the skids, i back off just a bit, and switch to idle one. i don't do 3d yet, but as time goes by, i will try it out. i can do very basic stuff on my 450. i'm getting alot better on my orientations too. i figure another month or so, and i'll be able to smoke the szabos.<----sarcasm, for those who don't understand it.:lol:

I don't.

I always start up in normal mode, and flip to idle-1 before lift off
If I feel I need the extra head speed in flight, I flip to idle-2

[Hover_X]

I see. Actually the soft start works really well on the Gaui ESC so starting at 50, or even 100 for that matter isn't really an issue.

[Ade_Law]

its good practise to have a normal mode so that when you move on to bigger helis its the natural thing to do.

on the gaui i run +/-9 (ish) with zero in the middle in all flight modes if you can hover then you want to be using this pitch curve so you dont have to relearn later on.

throttle curve in normal is 0, 50, 100

i only use that for spool up

throttle curve in idle up 1 is 75%, 75% 75%
idle up 2 is 100, 100, 100

this gives a slightly lower headspeed for hovering and balls out for 3d. This is on 2s 800mah lipo, these figures will be different on 3s

Thanks Ade,

OK, so what I hear you saying is that I want to get in the habit of spooling up in Normal mode with a somewhat linear throttle curve starting at 0 and then flip to Idle 1 or 2 as appropriate for the type of flying I will be doing. The Idle 1 & 2 throttle curves will be flatlined at a speed that I am comfortable with.

I guess I was thrown off by the fact that when I was starting up in Idle 1, the soft start works so well that it was not presenting an issue that I was aware of. I do want to develop good habits now though so when I progress I will not have to 're-learn' things that should come matural by that time.

As far as the pitch curve goes, what I hear you saying there is to setup the curve as necessary to establish +9/-9 degrees on the collective.

Thanks for the help and please let me know if I have not interpreted something correctly.

Definitely watch finless' video on pitch curves. It's just what you need imo.

[psindrup]

I would like to add, that I find it easier to fly with lower head speed.

Peter

[crabfu]

Yeah at first I was going for higher head speeds, thinking it would be more stable but twitchy is ok. After trying some thorttle curves, I find it too much easier to fly with a lower throttle curve. Something like 0-57-80-80 And yeah like everyone else, I take off at normal and not rely on soft start. I have my idle 1 just like normal mode, same pitch @ -3 +10 but slightly higher head speed, so it's more like a normal 2. And my idle 2 at 90 flat throttle, +-10 pitch. Experiment and find what you like :) Soft start works, but if you don't come to a stop, you can still get it to spin up at full speed in a split second.

I am curious why some people run 3 point curves and others 5. Any advantages to either? Why leave curve points inhibited?

Some tx only allows 3 points and not 5. You can also leave it inh if it's linear or flat at that part, i.e. 0-50-100 is the same as 0-25-50-75-100 etc.

Thanks Crabfu, I learn something new everyday in this hobby.
