Racing brushless 1/8 scale

I see, that's good, cutting CF wet.

from what i experienced with my lightweight e-maxx, lighter isn't always better.

It helps with getting a more agile acceleration, but it makes the truck less predictable in corners, (if there is a small bump, the light truck respons more to that than a heavier) and more nervous. too light isn't too good either IMO.

It works less hard, since its larger.. it's got a lower kv as well, which helps it too.. 8L is one hot motor compared to the 7XL. you can't do anything with the 'max amps' numbers. they are useless, it depends on what vehicle it's used in, and what gearing is used.

I agree with Serum, the xl motors are more efficient. The L cans seem to run hot and can't take as much as far as current. As serum said though, the xl works LESS hard, if that makes sense.

makes perfect sence.
lets see:
needed power to move car or truck to 60 kmh in 2.5sec's:
1100watts (not exact, just a guess)
L can motor more maxx power:
1200 watt (again, its an example.)
XL can motor max power:
1500watts.
so L can is working at: 91%
xL can is doing: 73%
of there maximum power.

thas is about right.....

that's good, i got it about right.
saweet.

Yeah, I've gotta tell ya, all of this trial and experimentation is starting to get expensive. I don't know what possessed me to get the 8L. I was thinking, "parking lot" racer.

Oh well, live and learn. When I went back to the 7XL, I didn't loose any speed on the track, temps went down, and I got better runtimes. Go figure. I'm just going to stop thinking about it and stick with the XL motors. The Feigao XL line is enough to satisfy me for now. The only thing I'm waiting for is the MM firmware update. When that comes out, I'm going to grab a Neu 1515 1Y, then that'll be that as far as my motor goes. The only reason I'm considering that is because of the efficiency and cooler running. One less thing to worry about.
