Definitely a bad unit !
Shoot an email to [email protected] …the guys at powerbox are really helpful and friendly and they will take care your problem !

On the other hand my mate removed his Cortex from his Viper and showed up this weekend with an iGyro 3e .
There is such a noticeable deference on the feeling and the smoothness over the Cortex he is staying with the iGyro 3e.
I think its something to do with the deferent algorithm they use i guess since powerbox one was originally designed for airplane use .

Once powerbox service your iGyro 3e ,try give it one last chance … goodluck friend
