Numbering on motor command is wrong (or strange), so wrong motors spin

* Deal with missing parameters on Solo

Temporarily disable MAVLink version check as the QGC settings have no effect and it will mess with the upgrade from v1 to v2 and has no real value

During tests, if the airframe was configured to be an 'X' type
we showed just 'X' on the airframe type. It's correct but a
single letter - specially an X - made users think that it was
a error code, not the airframe name. So, because of that, also
show the vehicle type - a wrong value, but elucidative for users.
