I used RIT Scarlet Red and Black. They came out like this-

I was hoping for a brighter red and solid black. They came out kind of lavender and really dark purple. So, I just went with it on the decals. It's not what I planned for, but I'm happy with it.

I just dyed some propellers the other day. Went with a nice black and they turned out a medium dark Blue...lol... I like your color scheme though, looks great.

Thanks. I considered using spray paint, but I was concerned about the possibility of adding weight, and inadvertently throwing off calibrations. I'm not sure if these are legitimate concerns, but it definitely caused me to go the dye route.
