I'd get a Funtanna 90, put at least a 100 four stroke in it and have some fun. It's a great flyer, lands slow and easy and can make you look like an expert. Built stock it needs a lot of weight in the nose, Balance it well forward of the suggested CG point. My first one I had to add 11 ozs. of lead to the nose. Second one I mounted the rudder on a pull pull and both evervator servos, with carbon fibre pushrods, 2/3's of the way back in the radio compartment. Balance was perfect and plane flew great and still is after 2 years of pretty hard use. You won't beleive how gentle it is landing and how well it performs.
Yeah this thing floats in by itself...
One problem though... It's discontinued and has been unavailable for months.
An alternative would be the Funtana 100X.
