hey tim2. i ran a factory team tc4 in vintage ta, 21.5 lipo. my fdr was 4.2. track was longer than yours but not as wide. after 8 minute main motor temped at 130 deg far, without motor fan. im not a pro at fdr but i would start at about a 4.5 and temp after every run. i don't like to get over about 160 tops. you can adjust from there. overheating these motors takes the life out of them and slows the down. gearchart.com has all the combo's.
again im not a pro, just what i have seen and heard in my 2 years of rcing.
