The aerodynamic drag, friction, power loss thru the drivetrain are three of the biggest factors that affect the top speed (assuming power is constant).
So assuming your TC is a 4WD, and the TC shell usually has a much higher aerodynamic drag than the 12th scale cars.. so the top speed of the TC will be lower if both car has the same motor, same battery and same rollout.
Yeah it is a 4wd TC with a rollout of 45.126mm. I was hoping that as a starting point I would try that number on my 1/12th but if as you say the lower voltage of the battery (yes it is 4 cells x 3700mah) will not be countered by the lower weight of the car.
Then I just guess I'll have to take a stab at a suitable rollout. Somewhere on these forums someone suggested a 38/100 spur combo but that would give a rollout of 59.6 which seems rather high for a 540 considering the hightest I've run was 50.8 at the nationals and that was rather hot lol.
