rudder to maintain Knife Edge, not climbing or diving. Perform
one full right negative Tumble by maintaining your rudder
setting while applying full throttle, full down elevator, and full
right aileron, releasing in time to end again flying Knife Edge to
the right. Note that you may need to use some positive elevator
and/or left aileron to stop the Tumble at exactly Knife Edge.
This maneuver is easier to the right because torque helps stop
the Tumble and it can be done at varied airspeeds with proper
throttle and rudder modulation.
VERTICAL HOVER
Fly a straight pass across the field at 75ft high and 100ft out
and pull the model vertical. Roll the model until the top of it is
facing you and slowly begin to reduce power. As the model
begins to slow down to 10mph or so, slowly add a little bit of
power back in. You will have to adjust the throttle as needed,
but make your adjustments smooth. Some right aileron may
be needed to keep the model from torque rolling. Use the
rudder and elevator to keep the nose pointing straight up. Be
patient as this maneuver will take a while to learn.
TORQUE ROLL
This is the same as the vertical hover but without the use of
right aileron to keep the model from rolling. If needed, you
can use a little left aileron to speed the roll up. As the model
rotates around, the controls will appear to be reversed to
you but only the orientation of the model has changed.
HARRIER
The harrier is nothing more than a high angle of attack flying
stall. Check the stall characteristics of your plane before
proceeding with this maneuver. Bring your plane across the
field at 75 ft high and 100 ft out away from yourself. Slowly pull
back on the elevator while reducing throttle. The nose of the
plane should come up. Depending on the plane/setup, you
may have to make constant aileron (wing walking) and rudder
corrections for this maneuver. As the nose of the plane comes
up, start adding in a little bit of power to help maintain
airspeed. The rudder is now used to turn the model. This
maneuver will take some practice as there are a lot of small
corrections made to keep most planes in the maneuver.
This is one maneuver where less control is needed. Too
much elevator and the model goes into an uncontrollable
stall. The C.G. of the plane will have a large effect on the
stability of the model during this maneuver. Some planes
perform better with more elevator deflection and a farther
forward C.G. while other planes prefer a further aft C.G. and
less elevator deflection. Elevator to flap mixing can be used
on airplanes with marginal wing area, and some planes
won't stall so elevator to spolieron mixing will be needed.
ROLLING HARRIER
Once you get comfortable with the up-right harrier, it's time
to work rolls into the mix. From an up-right harrier, add in left
aileron and change from up elevator to down elevator when
inverted. If you are comfortable with four point rolls and slow
rolls, inputting rudder on the knife edges can improve the
maneuver considerably. To turn the model, simply input the
elevator or rudder a little sooner or later in the rotation. It's
all a matter of timing.
PINWHEEL
Climb vertically and bring the model to a vertical hover, but do
not stop long enough to let the torque pull the model around
(climbing or sliding slightly will not be noticeable to spectators
but will keep air flowing over the ailerons and provide you roll
authority to stop the torque). When the model is hanging, rock
the plane left with rudder, then apply full throttle and full right
rudder and hold both, completing 3/4s of a VERY tight Knife
Edge Loop and flying out Knife Edge. When done correctly,
the plane pivots around the wingtip in a very small area. This
maneuver can be done either direction.
