Devo 7E - Switch Mode 2 to Mode 1

Hi, I've got a noobish question.

I am planing to purchase a Devo 7E.

After I put Deviation on it, will I be able to switch from mode 2 to mode 1?

I am asking because Banggood only sells mode 2 but I am used to mode 1.

Thanks in advance!

You can do this with and without installing deviation. The process is described in the manual I think. All it involves is opening it up and transferring a few things from one gimbal to another.
TLDR: yes it is possible and very easy
Also I think in deviation you have to choose what mode your transmitter is in once and then you are set (Y)
All the best and enjoy deviation !
