Back to the Odyssey Magnetic ring .. recalling before the engine went totally ballistic (launch at full speed) and before I saw the ring fall below the flywheel. The engine at slow speeds was a little erratic in that it would crawl along nicely, then all of a sudden jump up at 2 or 3 times the speed it was set at for about a foot of track length, them settle back down .. it would do it on and off at a crawl speed.. if I bump the speed up a little, this characteristic disappeared. When I took the shell off, I did see a hairline crack in the magnetic ring. .. I was touching the crack to see it was truly a crack or a mark and it was a crack,, I then put it back together ran it and that was when it lost speed control .. full speed or nothing, Taking off the shell a second time, that was when I saw the ring down or out place and when I touched it, it broke into 3 pieces .. So I am thinking the erratic speed was caused by the hairline crack until it finally failed and dropped out of place.
But when it runs, the Odyssey with the can motors crawls nicely and very quiet.
