My Titan is starting to burn out. the truck is starting to slow down, all the drivetrain and bearigns are still smooth and free. I can only assume its the motor starting to fail. cost aside what your experience with either the Kershaw single 700HO or dual 700HO. I have one Summit with the dewalt so that isn't a concern. I'm interested in a little more power/speed above the Titan with out going Brushless. I'm using SPC 8200 7.4v 50c LiPo's.
