The MG Hi-Nu's V-Fins are thin and a tad sensitive, and it broke during handling without me noticing it. So, with a knife, cement and 1.0mm plaplates, I crafted for it a new one.
The original V-Fin was made of two separate pieces. I simplified the new one by cementing a couple of smaller plates like so. Then I used a file to shape the fins sharp and added
I also made the new one slightly bigger. The overall effect seems to make the Hi-Nu's head bigger than it actually is.
