pitch curve and throttle curve for beginner

[ongbenghui]

Can you advise a pitch curve and throttle curve for beginner ?

is -2, +5, +10 reasonable or ?

[Adrianli]

Pitch :

-5
0
+10

Throttle :

0
50
100


Key point is to use correct pinion + motor to optimise esc.

hi hi,

I am trying to understand. at 0 degree 50% throttle, it wouldn't take off.

Am I correct to assume 50~60% is the hovering throttle and hence, hovering pitch ?

what model is your heli?

I would say

-3 at lowest
0 at mid
+11 at highest

throttle
0
50
85
93
100

You normally hover at around 80 or 90% of motor power. Hovering at low power is not efficient.

Or rather you should keep your motor spinning at almost constant RPM.

And yes, its not gonna lift off at half stick, it will start yo get off at above 60% stick. This is almost the norm for collective pitch helis nowadays.

my setup for all my helis for norm mode is always:

+12
+5
-5

Throttle curve i just adjust the mid point till i get good headspeed during hovering.

I am using a Trex 450 clone. The KDS450B that come with a 3500KV motor and 13t pinion.

Ok i know how to explain

There are 2 types of setup.

1. Able to hover at mid stick
2. Hover at about 60-70% stick

The reason why some ppl wants to hover at 60-70% stick is because when you change to idle-up modes, which grants you the ability to do inverted stuff, your mid stick becomes 0 pitch. This is because you want symmetrical response.

If you are hovering at mid-stick and you suddenly change to idle-up, you are going to fall.

Idle-up -
pitch -11 low,0 mid, +11 high
throttle 100% all the way or a almost flat V-curve.

Actually, i should find a website that explains all this in detail, kinda confusing explaining bit by bit.

yes my setup is same as yours.

mid-stick hover for scale and normal
60-70% stick for 3D helis so the transition is smooth between modes
