EXCELLENT write up by Paul! Lots of good info.
Desert Fox 4 suggested earlier that I contact Paul for amphib info, I sent him a private message but apparently he isn’t logging in lately, probably busy building something or flying .
My plans are to purchase an already built model 5,6 or 7 which should give me a gross weight of 1550 lbs., I fly solo 95% of the time so weight shouldn’t be an issue.

Thank you for pointing me to this write up, very informative and helpful.
Hope you put floats on your Fox, water flying is lots of fun.
