I am running a TC4 but not sure if I will get enough gear into if for 21.5/LiPo combo. I am on the high side of the FDR right now with no way of getting lower unless someone has a 64p spur smaller than 88t. Maybe won't need but we Will see.

You can get up to a 40t 48p pinion from SpeedtechRC

That combo will get you to 4.31 FDR. I'm not sure how much lower you want to go.
I will be running the 21.5 in my TC3 and plan to start with a FDR of ~4.54 (69/38) and go from there.

FDR = Final Drive Ratio, the combination of all ratios from pinion/spur to final drive. High/low is referred to numerically 4.5 being higher than 4.3, it's sorta backwards from traditional 1:1 car gearing lingo where a numerically high ratio is considered a low gearing.

Kimbrough makes a 48p 69t spur gear that should fit a TC4, it fits my TC3.
