I find this to be very interesting. I also wonder where the silver can falls into all of this, as it's commonly run in reverse on the clods and I have never had one burn out prematurely, compared to the front, that is to say, when staying whithin it's range of tolerable voltage (3S).taz11 wrote:I can shed some light on this part. I found out some interesting stuff about motors back when I was modding Power wheels. The power Wheels motors also have zero timing but the one spinning backwards almost always burned up first.andymac0035 wrote:They make a reverse-rotation titan monster 550 for use in the e-revo. This seems odd, as these monster 550's are supposed to have nuetral timing, but I have found in my personal expreience, that the reverse motor DOES run better on the rear axle than the normal rotation motor.
In reality zero timed motors are not truly set at zero. When a motor runs the magnetic field inside deflects with the rotation of the motor. The timing of the motor is adjusted so that it is timed at zero at its peak efficiency. However, when it runs in reverse the magnetic field deflects in the opposite direction throwing the timing out X2 (deflection plus the original correction).
If you want more info you can google "armature reaction" or "commutation correction" and you'll find some more detail on it.
It's also begs the question of how the HPI 15t firebolts fare (also neutral timing), as I know many of the brushed guys run these, and I kinda' want to try them out eventually myself. I like the e-revo titans, but between the length of the can, and adding to it with adjustable motor mounts, it sure is a lot to have hanging off of these gearboxes.
