This was the second one, it's not hard. Much easier than the previous model ES-kape. Mine is set up the same way, just the left side flotation. I doubt the gas tank bow conversion I did on mine would provide much flotation, one reason I'm not recommending anyone else do that, and keeping it a DIY at your own risk mod. Adding a larger plastic tank in leu of the stock aluminum tank, in the forward section of the cockpit, will help with balance enough to be worth the effort.
