Hey Bill,
I have just finished my KF. Many thanks to Kevin R. I have a post in "seaplanes" [link=http://www.rcuniverse.com/forum/m_2341739/anchors_8201618/mpage_15/key_/anchor/tm.htm#8201618]Anderson Kingfisher[/link]. I have an old Pilot Report on the KF that was helpful during the build. (see below)
Jerry Nelson of Nelson Hobbies has plans for a quarter scale Kingfisher that is more scale than Dennis' plane. Jerry uses some standard aircraft parts for the engine mount and retracts also. For a 120 to fly this plane I would think you would have to eliminate the fiberglass and shrink wrap it.
Chip, Knowing that the tail had to be kept light, I was very careful to use the lightest materials I had for the rear of the plane. I used .75oz glass and epoxy resin on the entire fuse and still managed to keep it under 16.5 lbs. It can be done.
