Upcoming Castle Outrunner Motors

[SunnyHouTX]

You are correct, with a CC 770Kv outrunner, the theoretical top speed will be about 66mph without any losses factored in. At 30% loss, top speed will be about 45mph. Of course I can set throttle EPA lower if it gets to be too uncontrollable. To me that point where I lose control comes in at around 60mph for a 1/8 scale. I am worried more about overheating and demagging the motor. I really don't want that to happen.

Now, when you say that outrunners don't make the same power as inrunners, does it mean that the motor will tend to overheat piddling around in my truggy? Or will the outrunner generate enough torque for a lower amp value (lower power) to move the truck satisfactorily?

Thanks MetalMan.

This is a hard comparison to make, considering the use of outrunners in cars is still relatively new and untested. However, for the same weight as an inrunner, outrunners generally are rated for less power. They do produce a lot of torque, as noted above, but I can't make a direct comparison to inrunners.

Just remember that your truck will require a certain level of power to move/accelerate, which won't necessarily be dependent on the motor.
