We're talking some explosive High Geared Torque coming from an Outrunner here. So Yes, the lack of a slipper is partially to blame for the problems. If there were a slipper, it could have been utilized with the setup. Inrunners don't have this type of Torque Period.

-IMO, I don't think that would matter would it? I mean if it's an inrunner of equal power is geared for the same speed, then the torque to the diffs would be the same, as all brushless motors have to the same torque curve (straight line)... and yah, it's too bad that any type of slipper can't be used with a setup like this.

There's a difference in the "flyboy" rating and our Land Vehicles. The Most Major one is airflow. The ability to shed heat is one thing that affects ratings alot.

-Completely agree with you on this one, cooling is basically the limitation to the continuous wattage rating (to a point), the better the cooling the closer the continuous rating will be to the peak rating. But still, that said, 2400watts for 440g is huge, so maybe the rating is taking into account that the components they use can handle high temperatures? However, that does not mean the efficiency would be very good at that output, if anything below average, maybe 85% or lower, whereas a Neu, IIRC, is roughly almost 90% efficient at it's rated output.


Another thought... I was just moving stuff around on the truck and was tilting the transmission 45 degrees one way and putting the motor centered in the chassis. Now if only I could make it work that way without heavily modifying the chassis to make room for it. If it could be done, then the motor would be centered, trans tilted to the left with steering servo on left as well, with Rx/rx batt on right side, and then twin packs on each side, should be 99% balanced then. Still thinkin on the ideas though.
