I have heard of guys asking if there are any 300a ESC's that will fit in a 41" boat, specifically the Fantasm. The swordfish was the popular choice, but due its size, it would not. Well for those that are still looking I happen to get a smoking deal on some Flier 300a HV esc's. These are mush smaller and lighter than the swordfish. They are NOT encapsulated in a heavy aluminum box. They are "splash" resistant which means nothing. I soaked them in the 3m electronics epoxy and slapped them in my Fantasm for *!***!***!***!**s and giggles. I haven't ran them yet, thats tomorrow, but here is how they fit. Snug as a bug forsure, but comfortable.IMG_20140121_215133.jpg
