They help a bunch...nice to hold an object with both hands while looking at it..

The Tamiya Brushless ESC 05SR is an electronic speed controller designed exclusively for Tamiya sensored brushless motors.
Dedicated brushless motor connectors provide an efficient power connection. Its parallel FET arrangement improves resistance to high current loads.
The motor connectors plug directly into the motor. A black-anodized aluminum housing dissipates heat and accepts a 25mm square cooling fan. Maximum RPM performance matches the TBLE-04SR.
The reinforced receiver-switch housing protects its cables. Its setup button adjusts battery cut-off, reverse, braking, soft start and neutral braking, with LED and audible feedback. Overheat and overload protection are built in.
