Mix for 4ch Helicopter

[solmer]

Hi, I've made a model profile for a 4Ch Helicopter (V911) and I've noticed that when the heli goes forward its needs a bit more throttle 'cause the main rotor speed goes down a bit, I've red that its normal so to compensate the effect I've added a mix to the channel 3 (TRH), when I press the ELV Switch (The one I've choose for the mix) if i push the right stick to go forward the throttle gets an increment of 10, thats works ok but if I pull the right stick to move the heli backwards the throttle looses 10 Its there a way to get it working only when pushing the stick to fly forward?.

Thanks in advance.

What was the mix you used?
Add the curve |x| to the mixer that adds ELE to your THR
This means take the absolute value of x, and so only positive values will be sent to the mixer.

Hi, this its my setup....

CH01
(+100%)Ail

* (+100%)CH06
CH02
(+100%)Ele

* (+100%)CH06
CH03
(+125%)Thr Switch(ID0) Curve(Curve 1)

(+10%)Ele Switch(ELE)

R (+125%)Thr Switch(!ID0) Curve(Curve 2)

R (-100%)MAX Switch(THR)
CH04
(+100%)Rud

* (+100%)CH05
CH05
R (+50%)P1 Offset (100%)
CH06
R (+50%)P3 Offset (100%)


Thx

Did you notice that your 10% ele only gets added in mode ID0 ? If you wanted it to work in the other modes also, you need to move that mixer line down one. So it would be like this:

Code: Select all

CH03
(+125%)Thr Switch(ID0) Curve(C1)
R(+125%)Thr Switch(!ID0) Curve(C2)
(+10%)Ele Switch(ELE)
R(-100%)Max Switch(THR)

I have to ask (now that I noticed), which version of Er9x are you using? Max was changed to half a long time ago.
Also I would change your throttle from 125% to 100% and just use the curves to control the throttle channel output. With them set to 125%, channel 3 output gets to the highest point on the curve before your throttle stick moves as far as it can.

Hi !

Thanks for the info, I don't noticed that the mix was only working for the ID0 mode Now I've changed it into the correct position
I'm on r788 , I'm gonna change the throttle from 125 to 100 also to get the full throttle at the end of the stick

Cheers
