Brushless eliminates the need for a glitch buster as they use less current. My 1274 snapped a servo arm this weekend. I never realized how strong this is, till I watch it in a turn and it holds it's line without flinching. I am used to the 1258, and needed to upgrade for 4x4. I had enough speed, but needed more torque. I am running at 7.4 on it.
