hey buddy pay careful attention to my posts, as they'll let you know what NOT to do.
The finned can 1521 will fit just fine, and is probably the way to go. I wanted my muggy to go 60+ also, that was until I realized just how fast that is, and how hard it is to keep the front wheels on the ground! Also, get LOTS of tire glue!!! You WILL need it! Can't say much about controllers, as the MMM is all I know, but Zippy batteries are supposed to be real good anc cheap too. FORGET the Road Rages for street use; they're WAAAAYYY too soft. You'll shred them up very quickly. Unfortunately, your only choice for street tires with this setup is really the HPI phaltlines, but as bdebde said, DO NOT(!!!!) buy the pre glued version!!!! Glue them yourself, and make sure you do a VERY VERY VERY good job!!! Also, I would avoid the chrome next time, because it just flakes off, and then they look very ugly.
Also, I bought the XTM 40 series wheels to mount dirt tires on, because they're the only other 17mm hub 40 series wheel, making it easy to use the hpi phaltlines for street. DO NOT buy these pieces of crap; I completely destroyed one the other day!! I have NEVER in all my years in this hobby, destroyed a rim. Just get used to changing hexes too.
BTW, I sure do love my muggy!! IMO, it's the perfect RC platform, though others may disagree.
