Mini Titan - Beginner's throttle, pitch and ESC

[Bunter]

Hi folks

I've looked through here and Runryder and have set the following up on my Mini Titan,

Throttle curve
Normal mode
In 0, 25, 50, 75, 100
Out 0, 70, 85, 85, 85

Idle 1
In 0, 25, 50, 75, 100
Out 90 flat

Pitch curve
Normal mode
In 0, 25, 50, 75, 100
Out 40, 45, 50, 75, 100
Pitch -3, X, 0, Y, +10 (not sure what X and Y equal)

Idle 1 mode
In 0, 25, 50, 75, 100
Out 0, 25, 50, 75, 100
Pitch -10, X, 0, Y, +10 (not sure what X and Y equal)

ESC
No discharge protection
Standard timing
No brake
Standard throttle response
Govenor mode on

Does that look about right please?

Many thanks in advance.

Hello, I'm also a rather beginner (have been flying heli for 2 months)

But I used a fixed flat throttle curve instead of the variable one you use.
and I don't do any 3D flying yet.

NORMAL MODE
THROTTLE:75%
PITCH: 40 - 70 - 95

IDLE-1 MODE
THROTTLE:95%
PITCH: 20 - 70 - 95

I might be wrong, so please correct. But isn't governor mode only usefull with a fixed throttle settings. The purpose of the governor is to maintain the same RPM speed with different pitch settings. So when you use a none fixed throttle settings, it kind of makes life real hard for the governor function.
Or am I totally wrong here?

I flew with variable throttle in the beginning, but the result was less flight time, due to the constant and uncontrolled power changes to the motor.

I also feel, that the heli flies much better with a fixed throttle and is more controlable, although it is more agile.

The settings are as such so when I switch between idle and normal mode, the heli remains stable, when switching during hovering because the change in RPM is compensated with the difference in pitch setting at hovering stick position.
Like this, I can easily switch from normal to idle and vice-versa without big changes in the flight behaviour during the switch.

Although this setup didn't work properly with the standard ESC. I changed the ES to a kontronic JAZZ ESC which in my humble opinion has a governor mode that really works very well, compared to the standard ESC. The standard ESC suddenly dropped RPM unexpected and did not recover resulting in bouncing of the heli.

But again, I'm only a beginner and this just my personal experience....but it feels good for me like this. Question is however, do I make sense here or not?

Some people like a bit of a throttle curve in normal even with the governor so they can stop the motor with the stick. Or like me where my radio complains if I turn it on with throttle hold on. So I turn it off and sometimes forget to turn it back on again...

Exactly that. I assumed that you can still use a partial curve with the ESC in governed mode without causing the ESC problems. Is this correct?

Above centre stick the curve is flat and so the governed mode will still be active in flight on the normal curve as well as idle 1 which is completely flat. I will have to wait and see how transitions between normal and idle 1 work out but as I'm a beginner normal mode will be fine for a while.

Thanks for the replies all.

Yes perfect sense, thanks for the reply. What I don't know is whether you can safely use a partial curve with the ESC in governor mode and still get the benefit of the governor when you reach the flat part of the curve? It would expect it to work OK but don't know for sure and am a newbie at this sort of thing. :)
