FEATURES:
Hand-Wound Armature – Our pro-level armatures feature a 1-3 pattern hand-wound wind with specific wire sizes developed to take all that your high power electronics can dish out. We optimize copper fill for best power and torque. Wind termination is reinforced using high-temp silver alloys, with state of the art epoxy resin impregnated coils. All armatures are then dynamically balanced with epoxy and the commutator is diamond trued. All armatures are stamped with wind. One cannot build a finer or more precise armature!

OPTIONS:
6 degrees of timing advance is popular and will not adversely affect motor life. When advanced timing is requested, it is our choice unless otherwise requested. With no timing requested we time motors at zero for no risk of improper installation
Brushes are bolted on with standard construction. If you prefer a soldered brush we will do this at no charge.
Custom winds are available upon request, and this option can be used to secure out of stock winds before they become available. If you have any questions regarding how we can fill your need, just contact us!
