Since the R1 subframe is aluminum, and the Bandit frame is steel, there was no way to weld it on. I had to fabricate tabs, weld them to the frame, and bolt the subframe on. This was by far the hardest part of the project.
The battery wasnt much of a problem. Since I used the entire R1 tail(including the battery box), I just decided it would make sense to use an R1 battery as well.
