We seem to have found out that the flatwire has better accelleration out of corners.
It would therefore seem to be better suited to small tracks.
Torque itself is pretty useless as a measure of power!!! (Oh my God, what have I said, I'll be skinned alive for those words.
) But why is torque useless yardstick? Because horsepower, the total power that the motor can put out, is Torque multiplied with RPM multiplied with 5252 (you could have different number, but 5252 is right for one measure of torque). You can have servo with 100 oz of of torque and nitro engine with 90 oz of torque. So if you used Torque as measure of power a car equipped with servo as motor would win over nitro equipped car. The nitro engine spins way faster than servo so car equipped with nitro engine would take the servo motored car and whip it. You have to consider RPM to see the real power a motor can put out.
The greatest hindrance to accelleration is inertia. It takes lot of power to get heavy things moving, less power to get lighter things moving. Armature with less wire is lighter so it spins up faster, it has greater accelleration (up to a point). To increase torque you need more wire which equals heavier armature which equals less accelleration (up to a point).
I'm quoting Big Jim from memory here. I confess in advance that my memory is not my strongest point. "Armatures with less mass of wire have higher rpm but less torque. They weigh less so they spin up faster wich gives more acceleration."
And here from
"Torque is what twists the tire, prop, or pump. Horsepower helps us understand an amount or quantity of torque. (Torque + time and distance)"
