I don't have a SD but I have WM Nemesis that I am converting to electric. I will be using a Hyperion 4035-500kv which is good for WOT 130A @ about 4500watts. I plan of using a 12 or 13 size prop possibly on 10s. Have any of you used this esc. http://www.hobbyking.com/hobbyking/s...hless_ESC.html
I have used there non hv version on 6s and worked out perfect.
