only 2700kv? Big G...the CRT may be a tank, but that 1.5D is a monster of a motor.
Using the TP 40c 3S on it is almost useless speed. The motor gets hot not from trying to power the truggy, but from all the wheel spin that's going on.
On 4S, that motor is absolutely ridiculous. The tires'll get almost as big as a paper plate from all the power. Run it more than three times and the foam inside the fronts is torn into three different sections. The duct tape I put on the inside of the tires ends up tearing.
That's not to mention all the damage it's done to the drive train. I've blown out an o-ring on the center diff, had to replace the center diff gears once already, rear diff gears are about to give up the ghost, blew the bearings on the front right wheel, bent the center universal drive shafts about 6 times already, bent the front three times and bent the CVD's at least twice.
I love the speed I have with this motor...but damnit if she isn't making me pay for my avarice.
