It's a great boat...it sails real good, and it's Deep V hull is made to jump big wakes. I bought mine, the Cruise 2, off of ebay a few months ago. No problems at all, and a very good watertight boat. The build quality is pretty good. No speed controller, it just goes on/off. But it has reverse. Yes there is loads of space to work with in the hull. Very roomy. The standard battery pack runs for about 8 minutes. I bought an extra 3300mAh battery pack to go with it and that lasts for about 18 minutes. The standard battery pack that it comes with is a 7.2v 1700mAh stick pack. It rides really well over the water and goes about 10 miles an hour. It will flip back up if flipped over in the water. I placed it in the water upside down and it flipped back up, with not a drop on the electronics. It comes with a pistol grip transmitter, and has a 300 foot range It's a very good boat...I recommed it.
