BRmini dual with GT3C hacked : dig issue

[Bergm@n]

hi guys

I've an issue with my BRmini dual from Holmes Hobbies and a Flysky GT3C hacked to manage dual esc.
I've setted up few BRmini dual with GT3 hacked for friends and never run in this kind of issue.

Issue is : when I dig the radio, one of the motor goes full throttle, when I dig the other way, it's the other
motor that goes full throttle.

What I've tried to resolve this issue :
- both esc are correctly calibrated with the radio : chanels are reversed, when I apply throttle : green light, reverse : red light
- radio has been flashed in 0.4 and 0.6 firmware, same results
- I've tried the radio on a rig with 2 castle esc : DIG is working as expected

I'm wondering if it's the brmini dual settings? but I don't know which parameter can act like this ?

Any idea guys ?

All I can think to suggest is to try and see what the servo signals are really doing when you are using dig.
A way to do that would be to plug a servo into each ESC channel. Probably have an arm on each servo to make it easier to see what is happening. Then use the throttle in normal and the dig modes. If you see the servos moving properly, then you know there is something strange happening inside the ESCs.

I tried a 4pl with both esc : all is ok so you will say it's radio or radio settings. I tried the gt3 with 2 mambamax, all is ok, gonna be crazy!!

I tried what you suggested to me and the result is that the issue is still here :
when I dig front one servo is moving to epoint, dig rear : the other servo is moving to epoint :roll:

More infos about my testing :
- I tried a 4PL on this set of esc : no problem all is working good even the dig
- I tried the GT3 on another set of HH brmini dual : same issue with dig :
if I push the dig display is " d 100 %" rear wheels spins full throttle forward
if I push the dig rear, display is " d -100 %" front wheels spins full throttle forward
- I flashed again the radio, reset, program it : same issue

Last firmware I tried is : 0.6.1.s.19
I programmed it like this :
Long Epoint : d - 3 - 0%
Long Rev : 3 - DIG - BMO - RE0 - PV1

That's strange.
When you select dig, one servo should move to the center. Would you agree?

Problem solved by Losikid : calibrate the GT3...
