Re: Positive or Negative Camber for DFW
Hi, recently on a test track, thought I had ourcar pretty wll tuned. Our car was significantly louder than faster cars on the track regardless of toe-in adjustments. What could this be? Run Cambered rears, and DFW, 3 wheels, smooth axles, krytox blend with teflon spray. Has anybody fiddled with plac...

Re: RA car questions - Side rail design
And what happens in the box at the end if the track? Is it full of foam, looks like an abrupt stop.

Re: Rail rider pulling opposite way? How to fix it?
Thank you guys we have districts today. Problem: rear wheels aligned with negative camber (bent axles). DFW positive camber with perfect toe-in. DFW inset at least 1/16th inch. Non dominant rear wheel still rides rail lightly. this can be overcome by adjusting dominant rear wheel to steer the car. D...

Re: Rail rider pulling opposite way? How to fix it?
i think that possibly the toe out issue on the right rear may be whats pulling the left rear into the rail? The confusing thing is that when doing the thumb tack front wheels off thing the car goes straight as an arrow for 5 feet, the car has even weight distribution.

Re: Rail rider pulling opposite way? How to fix it?
Thanks!, they are bent axles, so maybe, i will try to tweak. Race is tomorrow. I use a level tuning board and an 8 foot track. The axles are grooved so it is diificult to adjust the angle without bending within the groove which would obviously be bad, maybe i will swap out axles, and start over. The...

Re: Positive camber on DFW
Thanks thought maybe speed would push it out, maybe the rail Your description of seeming to "encourage" the DFW was actually right on. If the DFW hits a defect in the rail, it will slide a bit outward on the lubricated nail before it hits the nail head and jars the front of the car body. ...
