The heat sink is glued on the ESC, and I am really not sure how well it would take the anodizing... But as for motor/esc combo goes, this one is done for now. I want the new E-Revo.
I just have to say this is the nicest Rustler I've seen... it's going to be a shame to see it sliding on it's roof with that Mamba setup powering it. If you find out if your friend is willing to make more of those carbon plates, will you let me know. I'd really like a set.
