FLOAT FLYING BALANCE MOVE BALANCE POINT 1/4” TO 3/8” FORWARD

LAND FLYING BALANCE POINT

FOR FLAT BOTTOM WING

BOTTOM OF THE WING SHOULD BE PARALLEL TO TOP OF FLOAT.

THE FORMED STRUTS INCLUDED WITH YOUR FLOATS WILL SET

THE CUB WING PARALLEL

WE RECOMMEND THAT THE STEP BE AHEAD OF THE BALANCE POINT. THE STRUTS FUR-
NISHED WITH THE FLOATS WILL SET THE FLOATS AS DESCRIBED HERE

THE STEP SHOULD BE POSITIONED AT OR SLIGHTLY
AHEAD OF THE BALANCE POINT

Please note:
If your model has a semi - symmetrical or full - symmetrical airfoil, you will need additional positive
angle to be able to take off and land properly. also, the thicker the airfoil, generally the larger the
angle you will require. Some experimentation will be in order to fine - tune your particular model.
Float angles can be changed by the addition of plywood shims under the nylon bearings.

It is also important that the floats be positioned far enough away from the fuselage so the pro-

peller will be out of water spray. Keep these points in mind if you are making struts for your particular
model.

The angle at which the floats are mounted will affect how well your plane takes - off and lands

on the water. In our test, the cub flew best with the float top parallel to the wing bottom as shown in
the drawing above. The wire struts included with your floats are designed to set the floats parallel as
shown.
