[TowerTalk] Prop Pitch Motors

[Rick Mainhart]

Check with your local motor rebuilding shop and have them cut the brushes
for you. Our local "Fleet Hardware" can handle this task on a walk-in
basis. It DOES help if you have the old brush and an approximate length
required.

Hmmm ... sideline business pushing prop pitch brushes? 

73,
