I just got my boat and there is alot of foam in it so there will be no sinking plus it has a custom sealed sub hatch made from clear lexan that's pretty neat...I will be running it on 4s instead of 5s cause it was shipped with a 1515 2d (2050kv) motor. My boat guy tells me it will hit 50-60 no sweat and the speedo works flawlessly. Here's a link to my photobucket if you guy's want to see the set up shots.http://s283.photobucket.com/albums/k...riedfatnhorny/
