Default RE: Heinkel 31 Float Plane

Photos of our nearly finished Danish HM II (Heinkel He-8) float plane from RCM plans.

Power: Thunder Tiger .46 Pro. A muffler extension was needed to clear the fuselage & wing.

The plane is finished in red-orange as they were painted for the 6-year, Greenland photo-mapping endeavor. The bottom is silver gray. Fire red Ultracote covering and paint was used.

The floats are scale, squared off on front, flat bottom forward of the step, wide V rear of the step. The floats are built up from balsa, covered with fiberglass cloth and polyurethane and finished with fire red (top) and silver (bottom) Ultracote paint. The struts are close to scale. The inner sections are wire, silver soldered and covered with balsa. The outer struts from the floats to the outboard section of the wing are not load bearing and are made from streamlined tubing painted silver.

We had planned on pilots and a dummy radial engine, but have found that our usual source, Williams Brothers, have retired and closed up. My buddy, who built the plane, says he will get on making dummy cylinders in the future.

Next weekend, if the winds are nice, we'll test.

WW II & Korean war Marine aviator, Carl "Flaps" Laffert in the photo is the builder.
