1. This product is only designed for use with radio control models. Use of the product described in this instruction manual is
limited to radio control models.
2. Modification, adjustment, and parts replacement:
Futaba is not responsible for unauthorized modification, adjustment, or replacement of parts on this product.
3.Your Sky Leaf should not be considered a toy, but rather a sophisticated, working model that functions very much like a full-
size airplane. Because of its performance capabilities, this airplane, if not assembled and operated correctly, could possibly
cause injury to yourself or spectators and damage to property.
4.You must assemble the model according to the instructions. Do not alter or modify the model, as doing so may result in an
unsafe or unflyable model. In a few cases the instructions may differ slightly from the figures. In those instances the written
instructions should be considered as correct.
5.You must take time to build straight, true and strong.
6.You must use an R/C radio system that is in good condition, a correctly sized engine, and other components as specified in
this instruction manual. All components must be correctly installed so that the model operates correctly on the ground and
in the air.You must check the operation of the model and all components before every flight.
7. If you are not an experienced pilot or have not flown this type of model before, we recommend that you get the assistance
of an experienced pilot in your R/C club for your first flights. If you're not a member of a club, your local hobby shop has
information about clubs in your area whose membership includes experienced pilots.
8. While this kit has been flight tested to exceed normal use, if the plane will be used for extremely high stress flying, such
as racing, or if a engine larger then one in the recommended range is used, the modeler is responsible for taking steps to
reinforce the high stress points and/or substituting hardware more suitable for the increased stress.
