Medusa 60mm 2000kv in a Rustler??

[Raze ST Truggy]

Any reason this won't work well? With the revo 40 tooth spur gear, a 24 tooth pinion, on 3S lipo. The speed calulator says it will be about 54mph. Are there any other problems that I'm not seeing? My Rustler is a little heavy with the FLM chassis and as much as 4S lipo (so far), so I'm thinking of taking the 60mm medusa out of my revo to put in the rustler and buying an 80mm for the revo. Any thoughts?
