I find I can get the tank in and out very easily without a hatch. I glued a plastic strip to the front of the tank, and it sticks out so I can just pull and slide the tank out.

I don't have any problems with floating on landing. I found the key was adjusting the engine so it can idle low, and using a low pitch prop. I also find the roll rate with full span wings is very fast, whether in regular aileron rolls or snap rolls.
