personally i would sacrifice just a little of the scale of the cc01 and go for the scx10, its much more capable. and scince it has sealed bearings and comes with an electroincs box alls you would have to do to take it in water would be to put your electronics in the box and seal it with some silicon!

the sealed bearings and supperior axles will make a big difference and scince the bearings are sealed they dont need any oil, and the internaly of the bearings wont rust
