When the drop Colson is engaged, the entire chassis tips backwards onto the back Colson, or at least that's the idea behind 624's system. It uses the chassis geometry to avoid adding 2 more drop modules.

There is no versadrop for the back part of the chassis... am I missing something??? Can it still strafe?

The link is to 624's grassHopper drivetrain, by which the OP's drivetrain is inspired.
