When I am flying question

[Streetluge Chris]

Ive noticed when I fly my raptor 30 in a hover and move around a bit going up is fine but when I back off a bit just below 3/4 and around 1/2stick in Idle up the stick seems a bit dead i can feel the movement in the stick but have to push up a long way to get lift again.Its bit weird for a novice.
Is this down to expo?
the head speed is ok 1950rpm and pitch apears ok.

I was luck enough to get an hour today but its bl##dy cold.

Are you in idle up running +/-11 ish I take it?

Expo will only relate to the elevator, rudder and ailerons.
To liven up the collective response you will need to adjust the pitch curve.

It's not possible to tell what may be happening in your TX without knowing your pitch and throttle curves but one phenomenon when flying a heli is that if you descend into your own rotor downwash you will find that even when you get back on the throttle / pitch you may still be descending.

This is because your own rotor has created a descending column of air. This is particularly noticeable on a really calm day.

Full size helis always keep some forward movement when landing (until they have arrive close enough to the ground for a slow hover to touchdown) for this very reason.

In pitch curve I am only using -4 0 +10 I also fly very slow so the column air answer may hold true.Here are the pitch and throttle curves.
ST1
Thro
L=30%
1=30.5%
2=43%
3=65%
H=99.5%

Pitch
L=43.5%
1=59%
2=76.5%
3=87%
H=100%
DX7 more I ask the more I will understand I hope

My guess is your headspeed is all over the place.

I have found I need around 70% throttle at zero degrees to keep the headspeed equal to 100% at 10 degrees.

Looking at your curves you likely haven't even got 30% throttle at zero degrees (50%?), so as you raise the collective, the rotor will need to speed up before its generating a good amount of lift.

If you are flying with idle up there should be no need to adjust the throttle curve for what you are describing.

If it were me, I would try increasing the value of the pitch curve at position 3 slightly. You may find you need to experiment a bit to get the response your happy with.

Pitch
L=43.5%
1=59%
2=76.5%
3=87% <<<<<< Increase this slightly
H=100%

All that I can go on is that I am learning,
I now start to feel what the heli is doing. The old set up they put in at the club which was 3d I was flying this for a bit but it was to quick as it was
-10 +10 I think that why I notice its a bit dead around half to 3/4 stick coming down just don't seem right.
I can see what your saying, the rpm was checked at just below half stick and it was 1950rpm not checked above half stick.
I suppose this is where a governor comes into play?

I have a head speed monitor on mine - bought back when governors werent invented. Simple LED digits which displays the headspeed attached near the gyro.

Cant remember where I got it from though...poss Midland heli's about £5

Used to use these curves before i fitted a gov, they are still in there just in case the gov fails.... Maybe try them to see if they are any good for you. 1950 seems quite high, Way too high for woodies max 1700 for them. If your not doing 3d or idle up yet then 1500 should be plenty.

Normal
Throttle , 0,,,, 30,,,,,57.5,,,,,,,,61,,,,,,,,63
Pitch ,,,,,,30.5,,,,inh,,,,,50,,,,,,inh,,,,,100 (If you cant set inh then set a value to half way between the two values)
Idle up 1
Throttle 85,,,,,73,,,,,60,,,,,,80,,,,,,100
Pitch ,,,,0,,,,25,,,,50,,,,,75,,,,,100


The HS increases slightly from normal to Idle 1, but thers is not jump and its a smooth transisiton.

Hope this helps,
Simon

Apologies, ignore my comment. For some reason I thought you were flying electric; I've never fiddled with throttle curves on a nitro enough to offer any useful advice!
