No solder on solder Tabs on Mamba Monster Extreme
 

Made one Mamba Monster Extreme waterproof yesterday. Today I opened the second and noticed that in contrast to the first one there is no solder on the underside of the PCB where the motorcables go. The same for the small extra capacitor PCB. On the other ESC there is solder like on the battery wire tabs. Both ESCs are from an XO-1.

Is this is some kind of production flaw? Or just a 'design change' because it turned out that the solder on the underside is not needed?

What do you guys think, shall I add solder myself? Can it be done with a cheap unregulated 60w soldering iron?
