Thank you . The floats extend about a inch in front of the spinner ,,, They figure out to be 63.5 % instead of 75% . I have a float for the tail of the plane if I need it ! I am going to fly it off the snow tomorrow the way I have it set up now .. I will Remember what you tell me ,, I will Check incedence . and assemble a set of new floats to the proper length ! I will post tomorrow and let you know how it works ! Billy T.
