Rolling straight off power.
What to do??
- Wrong diff setting(too loose or thight)?
- Wrong weight balance sideways?
- How check tweak? Turning on the spring retainers?. Searced the net, but can not figure out how to de-tweak car
Tweak is unbalance or something I think
Also got some springs for center(gold, blue silver), side(blue, silver, green) and front(.18 &.20) if the problem is there. Also got crc magenta front/pink rears, not tested yet. Track is carpet.
Hard to figure out stuff, the rest of the club runs Corally or Crcs.
Set up: Lrp Sxx v2, Novak Ballistic 5.5, Airtronics 94819, Reedy 6500, inline config. 20 wt side 30 wt center. Gold center/blue side springs. Xceed Ennetti carbon carpet medium front and rear. CS tire sauce.
Could you post a few pics of your car ?
Most of the time when a 12th scale car doesn't go where you point it, it is due to a bound up pod, that doesn't articulate smoothly, the wrong tires/sauce technique, or diff issues.
This is not unique to the R5, it is true with all pan cars.
Springs and oil will fine tune a setup, as will balancing electronics on the chassis.
A proper diff should always be locked, smooth and free, providing there is a decent amount of grip available.
When everything is right, it's on rails.
