Ultimate RC Setup Troubleshooting Guide

Tips for using this guide:

• Start at the top: Recommendation are grouped by impact, so pick things to try from the top of the list first. Every car is different, so some cars will react differently to some changes.
• Test everything: This guide is directionally correct, but racing physics are complicated, and factors like weather and track surface and can combine to do surprising things. Remember to do your own testing to see what works for your situation.
• You have options! Our goal is to give you options to address any handling problem. Some approaches won't be possible due to your setup or parts on hand, so we offer several options.
• One change at a time! To truly learn how your car reacts in a given situation, make one change, test, and record the results. The So Dialed RC Setup App & Race Log is ideal for this!
• Check your baseline: Before trying these solutions, Make sure you don't have any settings wildly different from the kit setup. If you do, set those to the default first before trying anything new.
• Ask around: Folks at your track may already have solved the problem, and racers are (generally) happy to share knowledge, so feel free to ask!
• See a mistake?  Let us know!
