BrianG, point taken on the 1515, I too think probably a wise choice, not to mention more cost effective than the 1521s and probably as well a better fit for the chassis.
AAngel, you right, the Fiegaos are pretty much all I've experienced in an XL. I've ran a few Ls, still Fiegaos, but certainly no comparison to the XLs and I've run a few Novaks, again no comparison to an XL. So on that note, your right, I probably have no idea what I'm in for from a quality motor, but I sure looking forward to finding out

Any idea what your 8ight T weighs in at?
aqwut, interesting thought and does make some since. Hum, wonder if that's true or if it really just comes down to quality of the windings, mags, etc???
