2009 National Rule Changes

[Mikey B]

It doesn't seem to be posted anywhere about the rule changes that we discussed at the 2009 Nationals during the 'General Meeting'. I coudn't remember where to find the '2009 Rules' so I've copied the '2008 Rules' from the Mr Slotcar forum and made the necessary adjustments, thay are highlighted in red.
As far as I can remember, this is what they were:

Super 16D

5. Oilite axle bushes only, may be soldered or glued in place.
6. Front wheel retainers may be soldered in place.

6. Magnets may be “zapped” and glued by applying super glue. They must also be the original type and located with original magnet retainers.
7. The can may not be modified except for the following:
a. Notching for axle clearance.

Wing Car Ground Clearance
It was also agreed that all cars have a minimum ground clearance of .047" under the rear of the chassis. All sedans were already like this but now all Wing cars have joined the club.

There was also one other ruling that I can remember but I didn't put in in the GTP 12 rules because I wasn't sure. This was to allow the O/S Ultimate Caddy into the list of GTP 12 bodies, but I'm not 100% sure on this one, so correct me if I'm wrong.

Thanks, Mike.
