Thank you for your feedback, I've had a chance to have a bit of a play now since I have set up a decent home track, about 16m Carrera Digital, and I must say out of the box the slot.it McLaren can set a faster lap time (4.8s) than then mosler due to the magnet set-up in each. I've since installed a carrera magnet under the rear of the motor pod of the Mosler and it's ridiculously fast and stable (4.2s), feels like cheating, but hey my track - my rules. I took that magnet back out to go back in the carrera it came out of and put a small round magnet under the rear of the motor pod, lined up with the centreline, but its been less effective (5.2s) and now I can't match the McLaren again, dropping almost a second of its lap time. So I've added another magnet to my shopping list. I just started looking at the Thunderslot Lola mkIII, they look like a quality car with some good tuning options. I've also added that to my shopping list with some gears and suspension and magnet to see how it stacks up against these 2. I'll keep playing with the magnet down force for a while yet, but eventually I might take all the magnets out and stack them all up against each other in that format. As mentioned in previous comments with the speed of the magnets set-ups comes high speed de-slots, they weren't wrong! But the mosler is a tough little car despite its light weight, less inertia I guess.
