Hello,

I am using Futaba T14SG with R7008SB receiver and the DJI assitant recognizes the SBUS but when it comes to showing the gradual increase in stick values, it shows only endpoint either 10000 or -10000.

Can DJI staff please help me resolve this issue.

I think we are coming back to times, when DJI knows some serious bugs, but they will stay and watch with no answers... Same issue with A3 Pro FC. No help from dji...

I'm assuming the Futaba is already calibrated on its end and everything is updated firmware wise, correct?  Do you have the receiver connected to the N3 via SBus or SBus2 port? Could you verify the firmware and Assistant 2 versions you're running?

I guess you talking to Normap? I have a Futaba T8FG and as mention earlier a Frsky TFR8Sb reciver
I have only one sbus port on the Frsky tfr8sb reciver.And using assistant v1.1.2 and firmware 1.7.1.5
I uninstall the earlier verion of assistan 2 before I install the latest(v1.1.2

I saw this video clip:http://forum.dji.com/thread-79918-1-1.html .Were you link the N3 with a
futaba R7008SB2 Must I do that to? On my Futaba T8Fg I can only chose 3 modes:MLT2(that's what I'm using now), MULT or7CH.I have fly with the copter using a Naza earlier and that was no problem.
Whats worries me is that as I can see it this would not affect the problem I have with motor test,
Because the calibration of esc is done in assistant.But maybe it somehow it's linked to the
"endpoint 10000 or -10000" problem wich I have to Or should it be like that??

That is correct. Futaba was updated to the most recent software change listed here: http://www.futabarc.com/software-updates.html

The same device even before the update was working fine with S900 A3 setup that I have.

I managed to fix the rc calibration,I get a respond from support and it here it is: "About the remote control calibration, it should be the incorrect steps performed.
Please center the remote sticks, after the "Complete" button goes blue on the right bottom, you can please calibrate the RC.
If you calibrate the RC before the button goes blue, it will show this error. "

I tested some different ways to do this and suddenly I got it to work,now I have gradual increase in stick values! But I can't remeber how I did.
I think I centered the sticks waited to see the button go blue and then moved the sticks(now I had gradual increase value) to the endpoints and then centerd the stick again and then
pressed the blue button. I think I did it this way. test if it works.I have little time .

I also got motor test to work but it was after some clicking back and forth between motor speed
and idle speed so it is feels a bit "bugish"

Now I have problem to fly in assistanc simulator when I stops the simulator I get a IMU error  it is as follow: "IMU-altitude exception   please ask technical assistance for help"
I have replied to support will se when they resond back.

You can see motortest "bug" and simulator problem in this video:

In the video above I can't arm and fly in simulator.It work's now! It was my fault I had not check if elevator was going in the right direction...
It was now acting reversed as it should,so I revesed it in assistans and now I can arm and fly in assistan. So it was my fault sorry for that....

But I still get the"IMU-altitude exception   please ask technical assistance for help" after I stop the simulator.I can start the simultor and fly
again despite the IMU error. So dare I fly?

I am not able to solve this problem at all.
I should've listened to advises found all over internet about DJI services.

I'll be returning the units.
