Whether you're just learning to do basic aerobatics or are
looking for a quick practice plane as a backup to your
$10,000 Unlimited aerobatic machine, U-CAN-DO 3D is just
the bird you're looking for.
Large control surfaces, light wing loading and an all around
performance design work together to put a fun-to-fly do-it-all
3D aerobatic machine in your hands. With the U-CAN-DO
3D on low rates, it is a perfect choice for learning to do basic
aerobatics or for great Sunday fun flying. With a powerful,
high torque 4-stroke such as an OS .91, the U-CAN-DO 3D
provides exceptional slow speed and below-stall-speed
(3D) aerobatic performance.
For the latest technical updates or manual corrections to the
U-CAN-DO 3D, visit the web site listed below and select the
Great Planes U-CAN-DO 3D ARF. If there is new technical
information or changes to this model, a “tech notice” box will
appear in the upper left corner of the page.

1. Your U-CAN-DO 3D 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, the U-CAN-DO 3D 60, if not assembled and
operated correctly, could possibly cause injury to yourself or
spectators and damage to property.
2. 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 photos. In those instances the written
instructions should be considered as correct.
3. You must take time to build straight, true and strong.
4. You must use an R/C radio system that is in first-class
condition and a correctly sized engine and components (fuel
tank, wheels, etc.) throughout the building process.
5. You must correctly install all R/C and other components so
that the model operates correctly on the ground and in the air.
6. You must check the operation of the model before every
flight to insure that all equipment is operating and that the
model has remained structurally sound. Be sure to check
clevises or other connectors often and replace them if they
show any signs of wear or fatigue.
