Default Upgraded xp3A now motor wont arm help please

Hi

I cant believe this, i just upgraded the firmware on my xp3a and now the motor wont arm. What am i doing wrong? Is there a new setting in the latest suite that needs to be adjusted?

Here is my blheli set up



My throttle curves are flat 75 iu0, 80 in IU1 and 86 in IU2

I used to just apply th take it off and add it again and I would get the arming tiones on the esc now nothing!?

The tail is working on both brushless tail and none brushless tail versions.Main motors wont arm on either. Could it be my brushless tail also needs to be upgraded and this conflict is casuing the arming issues? That would be down in 9. something version... But what of the stock tail then?

Any ideas appreciated.

I wonder if it might help to rebind the heli to the Transmitter?
Or what about calibrating the throttle?

Does throttle calibration have to be done with a liner 0-100 throttle curve or just bind at zero throttle?
What if it can't for some reason see zero throttle?

I've never fooled with the software that communicates with these ESC's, looks pretty nice.

Hi

I reflashed the esc with software version 12.2 an it now arms must be a bug in the later versions that makes it incompatible with the xp3A. 12.2 was the highest I could go and it worked. 13 is where it starts not to arm.

Confirming the same, last workable for my XP-3A is blheli 12.2. Odd but for other latest firmware (14.9) works https://www.rccanada.ca/rccforum/sho...19#post3828019
