Silly me I posted the same question in (of all places) Radio and Electronics
. I got 3 responses, one of which was a copy and paste of the specs. Anyway, I'm glad someone else asked the question. It made my decision easier as well.
I think I'll go with the XBR and save some dough. I do this for fun and my driving and tuning skills aren't good enough to notice the difference in the 2 esc's.
Thanks guys for your input.
