For those of you who are not aware, this ESC will handle up to 8s. I have not tried any higher so I won't say that it can, I can only speak of what I know. So point is, if you don't want to spend the extra money, you can get 2 of these for close to the same as one swordfish. Granted I wouldn't run it as hard as a swordfish, longevity will surely be an issue, however if you are like me and only do a couple passes on 8s full throttle, then the rest just farting around, this is a solid contender for the budget minded...... just something to consider
