One good thing on 5s would be lower amp draw, easier on batteries, more consistent power delivery as a result as the battery voltage should hold a bit better. I imagine that might be very important depending on your flying style.
But even on 4s at about 1200 watts this only pulls around 82 amps or so. The 57"SC that I had with the Motrolfly 3625-800 was making around 1200 watts and flew with a lot of power. The Hacker A40-10s on my 55" Edge is a bit less, maybe 1100 watts, about 75 amps. I'm currently running Hyperion 4s4200 35c packs which weigh 449 grams. (My Edge needed a bit more nose weight than the 4s4000 25c Hyperion had).
Rodney is running these: http://www.valuehobby.com/product_de...=9&item_id=236
in his 57" SC, they weigh more than the Hyperion and are only 30c 4000s.
Guy is running Hyperion 25c 5s3300's in his 57" SC, they weigh about 455 grams. So the weights are pretty comparable from 4s to 5s.
I don't think 75-80 amps is too bad out of a 4000 pack, around 20c, and I like the flexibility of being able to double up for 8s someday maybe so I stuck with 4s personally.
