GWS EM300H

Comments

This is a Mabuchi RK370SD with a 45 turn armature. Brushes are timed for forward (CCW) rotation. Relatively low Kv makes it suitable for driving small props on 6 to 8 Nicads or 2 lithium cells. It can also be geared for use with large props on 3 lithiums cells (note: timing should be adjusted if motor is to be run in reverse).
