2 Switches 1 TX channel
6 Flight Modes
You don’t need to sacrifice 1 RX channel to mix 6 Flight Modes out of two switches.
Just mix Aux2 to itself in 3 different ways depending on the position of the
F Mode switch. You need to have Flight Mode enabled with the F Mode switch.
First go to Servo Setup and set Aux2 Travel to 85%
Then go to Mixing and select Mix 3, 4 and 5 und set it up as shown in the following pictures.
You will then get the Flight Modes a pictured below.
The good thing is, if the Flap/Gyro switch is in the middle (pos1) you always get
APM Flight Mode 4, which you could assign to Stabilize.
So you have still the channel Rud and Aux3 free for other useful things.
Comments
Manfred - Thank you so much for the additional info. I am looking forward to trying out the new instructions this weekend...
RE: !!!! And don’t forget to calibrate the APM channel 5 for the max and min PW !!!!
Apologies for asking but how is this done? Can you point me to additional info on how this is done?
I cannot express my thanks enough that all of you have taken the time to clarify things that must seem so obvious when you already know the proper procedures.
Peter
!!!! And don’t forget to calibrate the APM channel 5 for the max and min PW !!!!
Hi Peter
It’s actually dead easy, just be concerned about the AUX you like to have the flight modes assigned to, so let’s call it AUXx.
If you have your RC flight mode at AUXx and use the Gear and the F Mode switch to select your Flight Modes ,
do the following:
1. Go to “Switch Select” and link the Gear switch to AUXx
Have F Mode Inhibited.
2. Then go to Servo setup and set AUXx to 85% , 80% travel. (With this you can can then fine trim to fit the PW)
!!! Check with the RC Monitor if AUXx is going from -85 to 80 when toggling the
Gear switch. If yes, Good!
3. Then go to Mixing Mix2.
4. Then go to Mixing Mix3.
Check again with the RC Monitor if AUXx is moving if you toggle the F Mode switch. It should move on the left site from neutral if the Gear switch is down and on the right, if the Gear switch is up. If yes, Good, it should work.
!!! At Servo setup AUXx Travel you can then fine trim to fit the required PW readings for each of the 6 APM Flight Modes.
You will get 6 Flight Modes. If your Gear switch is 0 then you will get the first 3 when switching F Mode switch from 0 to 1 to 2, and if the Gear switch is 1 then you will get the second 3 when switching F Mode switch from 0 to 1 to 2.
Regarding your question: should I use Airplane or Heli for my DX8.
It doesn’t matter, use Heli, then you will be fine.
An explanation why I use Airplane, you will find in this link on the end.
Manfred, are these settings affected by which channels are assigned to Gear, AUX 1, AUX 2 and AUX3 on the receiver? I know I have followed these suggestions but I still can only get 3 positions working? Obviously I must be missing something? Is it possible I need to tweak the percentages in the mixes?
How do I go about changing the PW readings if these settings do not work? I think I understand I need to change the percentages for the rates? Is this correct? If not please clarify so I can get a better handle on how these adjustments need to be made?
BTW - It seems that neither of these suggestions worked for my DX8 settings? I must be missing something here but I just cannot figure out what...
Can someone please clarify whether I should use Airplane or Heli for my DX8 and Hexa-B hexacopter from 3DR? There seems to be differing opinions on this and it would be most helpful why someone would choose one or the other? My research seems to find that the majority of comments I have seen indicate that I should use Airplane.
Unfortunately this decision plays an important part as to which of the suggestions I should use for setting up the 6 position toggle switch for the various flight mode selections. I am having a difficult time getting my DX8 to work using the current examples because the information seems to be spread across several responses on this subject. It would be immensely helpful if someone could possibly take the time and post a brief step by step guide that starts by noting whether the settings are for Airplane or Heli and then guide the user to the relevant screens. Please keep in mind that new users like myself do not fully grasp how the Mixing settings will affect how the toggle switches behave so if any step is omitted from your instructions it would not be noticed by someone like myself.
Again I would like to thank those of you that have contributed to this discussion! Please bear with us who are new to the various ways that a DX8 can be configured. Eventually we will grasp how the various pieces fit together...
Manfred - can you clarify this, should I set the switch positions to match this example or were you referring to the Flap settings only? If so it would be most helpful if I could see an an example showing exactly what each of these settings should be.
Go to switch select and set it up like this: (don’t worry about my AUX3, AUX1 and Gear)
Gustavo - Manfred:
Thanks for your input. I will try your suggestions and post my results.
Manfred - The configuration file you posted is that for more than one model or a single model? Also is this for Heli or Airplane?
Hey Peter,
I have one hexa APM2.5 with the same tx/rx as you do. In order to achieve what you want (reducing the sensitivity for yaw and pitch control) you can do either two things or both:
Peter
I would turn down the sensitivity with the parameters of the APM in the MP
STB_PIT_P,4
STB_RLL_P,4.5
STB_YAW_P,3.5
and not with the RC Expo settings.
