Well the Q2 has been a problem with intermittent stopping, I put my voltmeter on the track and the drivers on the oppisite side and there was no voltage. I had cleaned the wheels so I knew that wasn't the problem so after many hours of head scratching I finally dawned on me that the trailing truck and pilot were lifting the drivers just enough so they randomly lost contact. There are no electrical pickups on them, both wheels are insulated to stop other shorting problems I am guessing. I can adjust them so the weight is on the drivers and that should solve the problem. It runs great without the trailing truck so I have made a start on fixing the problem.
