Modified Hovership MHQ2 for 7in props (338mm)

Modified upper and lower base to use with 7in props. Also the extended arm. All inspired by this project here.

Only these 3 parts are needed. Everything else comes from the original MHQ2 project.

I modified the lower clean section slightly to help snake wires and components through.
