Orca Vritra set up problems
 

I have an Orca Vritra pro2 which I bought to have as a spare and i cant get it to set the throttle and brake properly.It has the lcd set up box as well and i can use it to change all settings etc, but when i try to set the radio end points it sometimes stores them and then i turn the esc off and go to turn it on again and nothing.
I have gone through all the usual stuff and tried 3 different radios and receivers with different results from all 3, but none would hold the settings. Bought off here but didnt check it for a while and now its just a paperweight, looks as new.( possibly a software update but i cant find any relevant info on them)
Any ideas who would know about these.
Thanks:confused::confused:

Sorted
Tried a different receiver ,same as, then tried another handset and problem cured.Weird as the first handset works fine with everthing else.:confused::confused:
