Features

The Pro-120 has double 9.5mm motor tabs, for one
or two motors and single 9.5mm battery tabs. Also
fitted on the battery terminals is a set of 6.3mm
blades, to connect a charger or for similar purpose.

These are illustrated below.

Also available is an expansion connector option as

shown above, see section 12.
There are several on board options which can be
altered by removable jumpers:
