RE: Water Float question?
Floats work very well for flying off snow and floats will work nicely on your trainer for water as well however floats always have an effect on how the airplane flys but the question here is what floats do you have? Exactly how long are they? and how are they mounted or will you be doing that? The installation and orientation is critical to how successful they are flying both off water and just snow pack.
When using floats for snow flying its best you remove the existing water rudder if any. Snow flying can be very rewarding except around here we get the chance rarely perhaps only every few years. Interesting looking out the window this morning its snowing first time in three years, Oh man I gotta get those floats set up now where did I hide them.
