Gimbal install. How to determine if your 1.1.1 has upgrade

[WorldWideCells]

Im installing a Standard version H3-3D Gimbal on my phantom 1, V.1.1.1 how do i tell if it has the upgraded board already and that i don't need to order the GCU and PMU? My controller has the gimbal lever on the back if that means anything? Let me know thanks!!

Look in the battery door at the main circuit board. If it has 5 big oval holes, it's not upgraded. If it has 2 big oval holes, it's upgraded.
