what kind of floats
 

What kind of floats would you guys put on a avistar 40 thanx again coop . wood or plastic ?

you can put on pretty much any floats on a trainer ...as long as they are approx 3/4 the length of the fuselage. If you want sorta scale, and don't mind building, Goldberg makes a good set that are very popular, but there are others as well. If you ever get to a swap meet you may find some available....
