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

* Deal with missing parameters on Solo

* Fix trigger set

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.
