I appreciate the input. I originally set up the airplane with an OS 45FSR engine. I decided to drop down to the .030 after reviewing the instructions again. Primarily because with the 45 I was going to have to add weight to the tail to get balance. I built a seaplane years ago that failed for that same reason. I painted that plane and once I got it balanced it sat too low in the water. Another issue with swinging a bigger prop is that the 9" prop on the 35 is already chewing spray coming off the floats. Another reason that I am so interested in not adding weight.


OS.045FSR changed to OS 45FSR by moderator....
