Yep, those tiny little blade fuses (Mini-Blade) available at almost any auto parts store, I got mine at a NAPA. I just found a good location for the main motor fuse (18 amp on stock motor), under the belly mid-way between the ESC and the motor. I cut the (+) wire (mine was red), soldered the 12ga wire to each side of the fuse, be sure to slide the heat-shrink tubing on first[:@]! Then heat shrink the tubing over the stub ends of the fuse, covering any exposed wire/solder. I used a small zip-tie to secure the fuse under the battery tray.
I did the same thing with the tail motor (5 to 8 amps on stock motor), just mounted it under the canopy near the tail's ESC, same procedure just a smaller amperage fuse with smaller wire. You could buy the holders for the fuses, but I thought they were kinda bulky, and would add unnessasary weight.
I got my new Castle Creations Pegasus 35-P in tonight, overload protection or not it's gonna get the same treatment, as the POS that's on there now, the Evoflight 20. I'm thinking of smashing it with my sledge hammer, that may help reduce my (frustration/anger/rage) with trying to get that darn thing to arm!
