5s in slash?

[rootar]

anyone thought of running or has run 5s in a slash, i was looking at another motor for my slash and was thinking of going with a 36x50 medusa 1600kv on 5s 4000mah i was just thinking how of much runtime i would get over my 9L with 3s 5000 pack, i get 40-45 mintues with it how it is, so the more and effeicent and more powerful 5s setup should put me well into the hour+ runtime club, and by as a whole the 5s system only weighs 30 grams heavier so thats not even an issue since it basically weighs the same as a stock slash and 6cellnimh pack.

what the input guys? good idea or what? whats the rule we have at rcm no such thing as too much power right? i guess i could do a 1500kv 60mm verison, then id have a spare motor for my xray if ever needed?
