To match the other racers 2.8 fdr gearing, you can use the Robinson 49tooth(48p) spur gear with their 47tooth(48p) pinion gear for a higher 2.60 fdr... Make sure you have other pinions from 40tooth(48p) up to 47tooth(48p) to cover all the possible gearing from 2.6 fdr to 3.06fdr... The tc4 easily matches their gearing, and then some!!!....

The Second track is
Anything goes its a Huge outdoor asphalt 200+ ' strait that is where My Tc4 has the most trouble ( the FDR's they Run are from 3.0 - 2.8) Can't match their gearing with the Tc4's 2.5:1 trans. ( Yes I did dremel out the bracing under the pinion gear
)
The third and forth ones are Hobby shop Parking lot tracks, which I found on RC Tech .
One of them has good racers with good equipment .(A Tc4 challenge) . and the last has good racers on a lower budget, VTA always a lot of fun there (a Tc4 Nirvana
).
