That's probably my favorite car design

It looks like you guys turn the DRFW away from the rail instead of towards it. This is unlike the multi million view online tutorial suggests. To me it makes more sense that none of your spinning wheels is touching the rail. Is there a thread somewhere on the forum I missed, would someone discuss here(not really wanting to hijack), or start a new thread discussing at least this technique as it appears dominant among forum members? Eagle...If I'm correct I think you're looking at the overhead view of Skywalkers car ?....If so, judging by how much of the air shield you can see protruding ,I suspect the FDW is simply not tuned in that photo. . Your rears should never touch the rails, your lifted wheel should never touch the rail, the FDW is the only thing that should ever contact the rail. It sounds counter intuitive to have a wheel rub the rail, but it empirically results in a faster car. Ideally a car could run straight down a track and never touch the center rail, but it's highly unlikely , and certainly unpredictable. All else being equal, if a car could run perfectly straight and never touch the rail, it would whip an equal car riding the rail....but is it a chance you would take?

Ember So, likely the same on Mr B... 4.75” thread and pics? I see the FDW turning into the rail as it should. Look at the top view that has the fenders lying next to the car. I believe it's the 11th photo.

I don't think I'd tuned the car yet - certainly not in that second picture.
If I could get these exact fenders with a notch, I'd pop these off and replace them and run the car again. But I don't want to spend any time rebuilding or reworking fenders to work.

Unfortunately, no. Joe had forgotten to notch the underside of these fenders (and I didn't think about modifying them), so they rubbed the rail the entire length of the track. I think he designed a replacement with notches (but not exactly the same), but I never got back around to messing with it. Enthusiasm kinda zapped out of me after the work I put into this car, so I moved on. Don't you own a track? Are you not able to keep it up for testing? I do, but I currently don't have anywhere to set it up. I have plans to build a shop and track area in my attic but it's a pretty big project and falls behind several other home projects in priority.

Maybe if you pointed out that with a dedicated shop you could get your builds done in a more timely fashion and then spend less on overnight fees.
