As we were assembling the GoPiGo2 my 11 year old broke one of the leads to one of the two motors off. They are somewhat flimsy I must say compared to the rest of the design. I see you have replacement units in the shop bit with shipping to Norway being $35 for a $10 item I thought I’d ask if it can be soldered back on. I have a good iron, I just want to know if there are important considerations I have to make. It was the black lead that broke.
