Set up issue

[herman munster]

I'm setting up my Trex 600 and Axon with a DX8. This is my first time dealing with a flybarless heli In the setup wizard, I'm up to step 7 Diagnose.
Aileron, elevator, and tail are fine they all go -76 to +76
The head gyro -76 to +76 , works off the left trim button.
Horizon -76 to +76, works off right trim button
Tail gyro -48 in normal flight mode (rate)
+63 in Idle 1 (HH)
+66 in Idle 2 (HH)
+82 in Throttle hold
The gyro is set at Normal -100%
Stunt 1 +45%
stunt 2 +50%
hold +70%

Collective pitch -38 to +110
Throttle/ESC I get nothing

I take it that collective pitch should be 110 in both directions and if so, how do I get it to go lower than the -38 I'm getting
I don't understand why I'm not getting anything with the Throttle ESC.

I may be misunderstanding something, are you changing your endpoints so you get to 100, 100 both directions on everything?

You need to change your endpoints on the collective channel so you get 100,100

What channel do you have throttle assigned to and does it match in the software? What are your endpoints in the tx for your throttle channel? What esc are you using? Are you using satellites or a full rx?

Im assuming as you go up in flight modes you are also increasing head speed, correct? Typically you want lower gains the higher the headspeed. There is a lot going on here and please dont take this the wring way, we are all here to help but with this being your first fbl unit I want to verify... did you thoroughly read through the manual?

I guess I failed to mention that I have the Axon hooked up with the included wire loom. The endpoints in the tx for the throttle are 100-100. esc is an Align RCE-BL 130A, and I am using a full rx.

I haven't even gotten to the point of spooling up the heli, I'm still trying the get the Axon set up.
Yes, I have thoroughly read the manual, several time through, and I do understand you are trying to help, so I won't take any questions the wrong way, I appreciate all the help I can get.

All my endpoint in the tx are at 100,100

The settings I have listed above are what the Axon is showing with the endpoints all at 100, 100

[AndrewJHawes]

Sorry, you have misunderstood the instructions a little, and reversed the logic.
You need to adjust the end points in the Tx, so that you attain -100 to +100 on the disgnose page (not the other way around).

[AndrewJHawes]

You probably need to make sure that you have your throttle assigned as Channel 3 and your collective pitch assigned as channel 6.
Look at the diagnose screen, and confirm that you have these signals working.
I am assuming that you have started with a fresh 'new' model, and have your throttle and collective pitch curves set in the model in Tx as linear 45 degree +ve curves.

Please adjust the endpoints in the tx til you get 100,100 in the Axon. For example my tx shows 109,110 but the Axon shows 100,100 .... this is what you want to have.

Alright, that cleared up most of my issues as I adjusted the endpoints in my radio and was able to get 100-100 in both directions for everything except collective pitch and throttle/esc, so we're making some headway.

With collective pitch I was able to get +100 with 81% in the radio but only get -77 with 150% in the radio.

As for the throttle, I think the issue might be with the esc. When I plug the esc in, the light that is next to the plug in for the asbox is flashing a repeating single red, which according to their manual means no throttle signal for over .25s. They offer no remedies for this. I have my throttle plugged into the rx, which is what the Axon instructions say to do

Andrew, I did start with a new model and the throttle and pitch curves are linear 45 degree

[herman munster]

Thank you very much for your help Chad , Andrew, and Danny.. Between what you guys told me and my phone conversation with Danny I was able to get my issues taken care of and get a better understanding on setting up the Axon.
The issue with the throttle/esc not showing anything on the diagnose page has to do with using the loom for hooking up the Axon. When the loom is used, the esc is plugged into the throttle channel on the rx and because of this the Axon doesn't see any throttle input, so the throttle/esc on the diagnose page isn't used.

[AndrewJHawes]

Glad to hear you have got this sorted out.
It is also very important to be aware of what your transmitted signal is doing by checking on what the transmitted signal looks like on the 'servo' screen, or equivalent, on your transmitter, in relation to the display on the diagnose screen. This is important if channel reversal is required (usually for throttle signal between radios), and awareness of different flight modes, for example, where curves have not been set to default.

I've never really paid much attention to the servo screen (monitor screen for spektrum) until I started setting up the Axon. like you stated It really does help to understand what a control is, or isn't doing

Like most fbl units, they are a bit of a pain the first time, but are pretty easy after that.
Coming from a fly-barred set-up for the first time is difficult, especially with all the new jargon, but most fbl units operate in essentially the same way, and the process of running through the required set-up steps is pretty much the same. Just slight variations in the jargon used, and meaning of terms.
Once most people have got to the grips with the basics, they are not too bad, and few then want to transition back to the old flybarred style.
Good luck! I am sure you will enjoy how the Axon flies.
