Re: Testing cars for USD compliance

Guys,

Hope all is well. Sorry for being out so long, but you know how construction dictates your pace. Every thing get push back a week or two maybe three. lol.

Last night was the first on the forum since I actually started my work. This was possible while looking at the US Election results.
I see we still have healthy discussions on the board and exciting things ongoing. I have looked at the new rule and i think it is a good sugestion.

The car you choose is by preference. That is a non issue. Case Closed. That should not even be in the discussion.

The only thing is see is that the car that is checked last is at a very slight dissadvantage, since the magnetism is a little stronger. By how much, that is yet to be determined.

If you paint arrows in either direction and check it in one direction and it does not drop away. You check it in the other direction if it does not drop away the car fails inspection.
Case closed.

This gives you and everyone an equal opportunity and fairplay.

My 2 cents.

Arden

Hi all,
Now reading all the responses to this topic which certainly seems to have gotten some attention. I'm defininitely in agreement with enforcing the rule as written. I agree that the test strip may very well be slightly more magnetized than one at home but I'm sure that if so, the difference in downforce generated would be very small. It would be the same for all however, and as Gordon said, a standard for all must be established. I think that a workable approach would be to prepare one's cars so that they are not at the absolute limit when tested at home, in other words, leave a little leeway. The other point mentioned by Ramesh is (if I understand correctly) that some cars would be inherently better at generating downforce due to the differing fulcrum effects based on their chassis/motor layouts. I think that while this may be so, there should be no change in the rule because of this. Just as in real 1:1 racing, some layouts may be better than others (eg. front wheel drive vs. rear wheel drive) at different tracks, or even at the same track in different conditions, the rules are, in most cases, consistent . Let's not make something difficult out of something simple. The alternative to this would be Magnet Marshal testing which would be so much more inconvenient.

Arden I think that this is a perfect suggestion. It gives every car two chances for each test. If a car fails both it can be adjusted (see this post: viewtopic.php?f=8&t=1095) and then tested again.

I've adjusted the testing procedure to include Arden's suggestion to test the car in two directions if necessary.

Gordon,

In a sense ~ too many heads "didn't" spoil the broth ..!

Replies from all directions made the simple USD rule ~ turnout even simpler.

It's a neat easy going adjustment for all ~ from such user friendly feedback :)
