Ran Jilles setup yesterday at the Tamiya track again. Traction was less than that of the Reedy Race, yet was able to match the 13.5 fast lap of 12.6 Very promising. Also, a friend tested the setup as well, but with Xray springs of a *similar rate*...was frustrated and nearly kinked it on purpose to be done for the day. On the last run, he switched to HPI springs, which resulted in a quick, consistent, error free run, with a smile.
