New user - to Phoenix

[sargan]

I am 'new' to trying to get to grips with a Heli simulator, could those that know help check my set up?

I have Phoenix ver 5.51
I have it connected to a Spektrum DX7

I would like to know if I have it set correctly.

I have selected Spektrum DX7, gone through calibration and also reversed some controls.

If I look at System>Controls
under edit profile ... if I move left joystick from bottom to top ... Engine bar graph shows as going from 0 up to about 100% but as I continue the stick past 3/4 position throttle then drops back to 50%

At same time Collective pitch bar goes linearly from 0 to 100% ........

Is the throttle & Collective relationship correct ? The throttle and pitch match each other to 50% stick .. then throttle increases faster until at 3/4 stick it is at 100% then it reverses and lowers to 50% ... while pitch goes on smoothly to 100%

Rudder is fine

Elevator/Cyclic at centre position bar is at 50% if I move joystick to top then bar smoothly moves to zero and smoothly to 100% if I bring stick down.

Aileron - centre is 50% - if I move stick to left bar goes to zero , and to 100% if I move to right.


Is this all correct ?

Throttle strange, what's it say in your Tx IE throttle curve rest sound okay. Does the heli fly apart

[sargan]

This is a default new install of Phoenix.
The curves on the simulator for both throttle & collective are linear ... bottom left to top right.

or did you mean on the DX7 ....

[waveydavey]

Yeah your transmitter. Make sure the throttle curve is right

[sargan]

Yeah your transmitter. Make sure the throttle curve is right

This is all new to me .. so unfamiliar with DX7 settings.

I created a new blank entry ...(as Phoenix advised) if I go to the Throttle curve screen it shows:

[waveydavey]

Set that to 0-100

[sargan]

Set that to 0-100

You couldn't give me a quick pointer on how to do that ... all new to me.

I did find that instead of 'norm' the next screen is 'ST1' and that is a linear curve .. so now that curve shows under 'throttle curve'
Though I still get the same response as described in initial post

[waveydavey]

Scroll through the points using the wheel and it will select the values on the left of the screen, change point 1 to 0,25,50,75,100 point 5 and you're good to go. Or start with a new model menu and it will be the default

Not sure what you mean ... 'wheel' I don't have any wheel.

Anyway the Throttle curve had the word 'norm' and it ... I used selection button and found a liner straight curve 'ST1' as this now shows when I select the settings assume this is now the 'working curve' ? or do I have to do something else to make this the active curve ?

On the Phoenix Sim

Still does not seem right for me .... using left stick only ....
Moving from bottom to top collective pitch alters smoothly 0-100%
Throttle behaves almost linearly for first 1/2 of travel ... response on screen is 0-50% (almost matching collective response) then ... from 1/2 to 3/4 position of travel it is logarithmic in response hitting 100% around the 3/4 travel then back down to 50% as you finish the last 1/4 of travel.

Curve on phoenix is set to linear

[sargan]

Anybody any other suggestions ?

[Mike Sanders]

Do what waveydavey suggests. Set your throttle curve in norm. so that it is a straight line with 0 at the bottom left and 100 at the top right. Read the DX7 manual as to how to do it. This should give you a linear throttle output.

Look at your pitch curve as well it should be similar.

[waveydavey]

Anybody any other suggestions ?

Sorry about the wheel reference, long time since I had a DX7 What happens in your channel/servo monitor, see what the throttle channel is doing. It should be going up and down with your collective. If it is then it's something in Phoenix itself. Let's establish where the problem lies first and we'll go from there.

[sargan]

OK made suggested changes and results have 'changed'
On DX7 I set for 'Norm'
L:0
1:25%
2:50%
3:75%
H:100%

Is this correct ?

Now with this setting on In Phoenix I go to:
System > Your controls
> Spektrum DX7 copy
> Edit Profile

If I look at Collective bar ... it goes smoothly form 0 - 100% as I move stick from bottom to full travel

The Throttle bar now is going from 0 at bottom of travel smoothly up to 50% when stick at full travel.

So getting somewhere now need it to get to 100%

Have you done the transmitter calibration in the phoenix software.

This teaches it the full travel of sticks and switches

[waveydavey]

It's the fact it comes back after 50% not sure the calibration would do this, even if it were calibrated with throttle at low stick and not in the middle. Unless it gets max at 50% and that's it. Worth a go though
