Yes, your observation about torque is correct. What you can look at for torque is the rollout number also. This ratio is the number of inches the wheels turn for each revolution of the motor. So with your gearing the tires are turning 0.85 in. for each revolution of the motor. This is actually a very high torque setup. If you had a rollout of 3:1 this would be a high speed but very low torque setup because each revolution of the motor is turning the wheels 3 inches. I try to keep my setups between 1:1 and 1.5:1 and they have worked out well that way, with a good balance of low-end torque and good top speed.

If you haven't already purchased your lipos you might consider going with 5S, because on 6S your RPM are pushing towards 50k which is pretty high, I would suggest trying to keep them in the 30-40k range. Even on 5S you will still be able to gear for 35-40mph and still have plenty of torque.
