SECTION 17: FLYING THE ULTIMATE BIPE EP
The Ultimate Bipe EP is designed for those pilots who are experienced at flying sport models. It is not a trainer. If you do
not feel comfortable about test-flying the airplane, don't hesitate to ask someone more experienced for help.
When set up for test-flying, the Ultimate Bipe EP is much like flying any other sport aerobatic airplane and because it has
a relatively low wing loading, the airplane is predictable during low-speed flight and landing. You should find your first few
test flights enjoyable.
TAKING OFF FROM THE GROUND
It is important to let the airplane get up to flying speed before lifting off the ground. Lifting the airplane off the ground too
fast will cause the airplane to stall and crash. You should allow the airplane to roll out until the tail is completely off the
ground and flying. Allow the airplane to roll out on its main wheels about 50 feet more and then gently pull it off the ground
and into a shallow climb. Because of the torque of the motor, the airplane will have a natural tendency to pull to the left
when it is accelerating down the runway. You will need to compensate for this by applying and holding right rudder during
the takeoff roll. Once the airplane lifts off the ground, you can release the right rudder.
IN THE AIR
In the air the Ultimate Bipe EP is smooth and predictable. At full power, the motor and propeller combination produce
enough torque to pull the airplane through just about any maneuver you want. You'll find that the airplane is responsive
to control inputs and handles light winds with ease. When trimmed and set up properly, the airplane goes where you put
it and tracks like it's on rails. With the C/G set toward the back of the range, snap rolls are crisp and very little elevator
input is necessary for inverted flight. And because of the generous fuselage side area and highly effective rudder, knife
edge flight is very easy. All this results in an airplane that's easier to fly during more difficult maneuvers like 4-point rolls,
rolling circles and slow rolls.
LANDING
Like take-off, landing should always be done into the wind.
Prepare for landing by reducing power and making a shallow turn into the wind. (With power off we strongly suggest
avoiding high-banked turns.) With the airplane on final approach it will begin to slow down and descend. With the
airplane descending, apply small amounts of up elevator to slow the airplane's speed. Just before touch-down, turn the
motor off and let the airplane settle near the ground. Flair just before touch-down and you will be rewarded with a soft
landing. As always, when landing, be careful not to over-control. Over-controlling leads to excessive oscillations which
don't make for good landings. You may find that the airplane lands easier if you come in slightly faster and land on the
main gear rather than trying to slow down to do a three point landing.
