Aurora Tech Talk

I think next thing on my shopping list will have to be a gauss meter

Is it a big difference in strength?

Definitely X Traction, I took them out of an X Traction chassis

Fitted them into a MT chassis and gave it a spin around the CHORC track last night, and then my normal race car, there was no comparison

Here's a thought, although unlikely, I don't suppose the magnets are stronger in the 4 gear chassis and the Ultra G. I think it was magnets from an Ultra G that I used but I'm not sure.

I have my front as low as I can get it and the back jacked up quite high

I've just tried measuring the tyres but it isn't easy as the fronts are somewhere between the front wheel sizes and rear wheel sizes on the tyre gauge, and the rears are too big for any of the holes

I pretty good guestimate would be around .390 Front and about .480 rear

Mine are 385 front and 454 - 460 rear depends on the chassis

Wish I could find some that smaller for the front

OK I got another UG and 4G today, at first glance the magnets don't seem any stronger but I have a couple of ideas

On my normal race car the white magnet is at the front but on the two I've prepped ready for testing it's at the rear, not sure if this makes a difference or not as it just looks like they're painted wrong the polarity is the same on all three.

I've now fitted the wider AW pickups on the other two and my theory is this, not only is there more area to touch the track but there's more area near to the front magnets, in essence they act like a flux collector, a bigger flux collector than you'd get just using the narrow pickups, a bigger area for the magnetic pull to pass though!

Whether this is true or not I don't know, all I know is this; I can't get the grip from any other car than I can with the original that won the pancake cup and xmas do and that is the only car I've run wide pickups on so far. Maybe I just got lucky with the magnets, or maybe it is the pickups!

More testing needed
