our district rules read
A15. Wheels can be sanded to remove surface imperfections; however 1/4” of the tread width must remain flat, and
parallel to the track surface.
Can i Still make a railrider? And what is your defintion of parallel?
(just trying to find a grey area)

That rule is a little strange, but I have seen similar rules that say something like 80% of the wheel tread must remain flat...
Yes! You can build a Rail Rider! Put a light cant on the rears and on the FDW and (if legal) lift the other front wheel. If you use a light 1 or 1-1/2" degree cant then the wheel tread will lay flat when static and will migrate when rolling.

In answer to your question about anyone else doing this, 5Kidsracing is right on with the cant for the wheels. Not sure how they are going to be measuring exactly 1/4" of the tread not being flat though. LOL If you have the rail rider tool, it has a 1.5 degree side which you could use for front and rear wheels. It will basically give you a sliver of daylight under the up side of the wheel but that could put you a little closer to the rule limit than you want to go. Otherwise, you can perform similar with a manual bend of the axles. A very slight bend will get the rear wheels at the axle head and away from the center guide rail but yet it can still leave the wheels appearing flat on the track. A slight angle to the front wheel may not be enough to get the inner edge off the track but will still allow you to get the drift for the rail rider. I would guess by the rule that you cannot run either of the front wheels up. Run the non dominant front wheel straight. You would still perform the 1/16" cut in on the dominant wheel side. I always check alignment on the block right after drilling axle holes and I would certainly recommend that here. Such a slight bend in the axles will not be enough to overcome poor initial alignment.

Does that mean you can make your wheels 1/4 " wide if it's flat ? And yes you can make a RR
