Ok, i was told i would find them on this site but cant seem to come across them. I was told obviously they were different for the regular 18" BTL. Thanks in advance for any direction of help...

what do u mean by specs, do u mean parameters? all the specs are on FI website, and also at the top of the technical section there is the BTL page.

yes the specs are different for the fully loaded motors.

i THINK they posted the specs up for fully loaded btl's a long time ago. im not sure however, and cant find them anyways lol

Yes, specs was posted once upon a time.

I remember teh thread.

But I dont know, if it made teh transaction when SSA, moved severs.

here are the old ones. i know that they have the new cooling thing, so they might even be different from these but here is what scott posted

Here are the specs for the current fully loaded BTLs (3rd magnet, high Xmax coil, and full cooling).
