Guys

I have discovered a new tool needed for flying a large BRUSHED motor plane. A commuter cleaner (four bucks). I thought my motor was going bad or that I needed new brushes. I talked to a CAR/Boat guy and he told me to get the commuter cleaner. One end is shaped to go down the hole where the bushes set. Push it in and spin the prop. The commuter, which makes contact with the brushes is shinny new. The other end is shaded to clean the C shaped brushes. My commuter was so dirty that the Speed control would not boot up. No complete circuit. I thought it was bad. Thanks pmpjohn for the advice.
