For my 2cents worth, The mini fuses for the controler first. They will help save the 3-in-1 or a 4-in-1 with a blade strike and overload of the electrics. It has already saved mine once. I added it to my BCP after I saw it work at the field on a very experienced fliers CP, then did mine.

ZENCHAL26 , good pictures. Where did you get that double mini fuse mount? TIA, Andy
