There is no way to know definitively if a given setup will work ok, be fast enough, or be perfect, etc... it may come down to how you drive and what the track is like. The same setup might work great in one situation but overheat in another with the exact same car.

Let me add to the total confusion :) I have not run a 10L and I only testran the 9L. What I have run the most is a frankenstein motor... that is part Hacker and part Feigao. It's a 12L but it may not run like a normal 12L, but I have no idea. It seems to be faster than it should be... in fact the 9L felt pretty similar when I ran it.

Anyway, I raced the "12L" hybrid and it was fast at 11/46... and easily thte fastest car on the track at 13/46. It was retarded fast as I was told a couple of times. I think the MM could handle this motor esp if I put a fan on the MM. But this motor would thermal a MGM 120 and Mtroniks Truck, which I ran with the built-in bec. That could have been the problem with the Mtroniks.

Hope this helps.... I guess if you keep the buggy as light as possible I can understand going with the L over the XL. You should be able to get it under 7.5lbs with a 4000 pack. Both my cars are right at 8 lbs.. the Kyosho on 6000mah and the 8ight on 8000mah.
