because from what I have seen 70 amp isnt nearly big enough!! Randy from BBY racing recomends at least an 80 amp for the 540 size 8L feigao. but for 40 more dollars why not get the 125. plus i may want to use it in a bigger boat someday. I've seen way to many guys at the local electric boat club have problems with esc's shutting down and I dont want that aggravation!

and how much money am i really gonna save. i bought the barracuda 125 for 159.99 at my LHS. Its worth it to me to spend a bit extra and be safe
