WT-01 Add rear steering

[-=Jeff=-]

I am thinking about adding rear steering to my WT-01..  While adding it would be straight-forward I do want to add options and curious how I would to that

Here is what I would like

-Rear steering as normal..

-Switch between, Normal, Crab or No steer in the rear from the remote

I have a Hacked Flysky GT3B so I have up to 8 channels if needed, just need a new Receiver

 

Thoughts?
