transitions. This will allow you to practice nose-in and still
give you a chance to get out of trouble. As you improve you’ll
remain nose-in for longer periods of time.
Forward Flight: Now it’s time to work into basic forward
fl ight. Just take the basic hovering maneuvers listed above
and slowly fl y out farther and faster and always bring the
helicopter back after one pass. Practice controlled slow fl ight
in close as well. The more time you spend practicing here the
easier things will be later on.
AEROBATICS
So you are getting comfortable in fast forward fl ight? Well,
now it’s time to slowly progress into aerobatics. Once you are
in forward fl ight start using the idle up switch which raises
the rotor RPM for aerobatics and allows the AXE CP V3 RTF
to fl y inverted. Also, in wind it may be diffi cult to descend to
land without the idle up on.
Chandelles: Your fi rst step is chandelles. Fly straight across
in front of you and pull up to a 45° angle. Now at the top, when
the helicopter slows down to a stop, apply left or right tail
rotor to bring the nose around 180° and continue back down
the 45° angle. As you progress with the maneuver you can
pull a greater angle than 45°, but 90° would be considered
a stall turn.
Loops: Once you become comfortable with the chandelles
and stall turns it’s time to move onto the loop. The key to the
loop is to enter with plenty of speed. Start pulling aft cyclic
to enter the loop and as the model transitions to inverted at
the top of the loop pull back on the throttle (towards negative
(–) collective) this will help maintain altitude. As the model
returns back to vertical add some positive (+) collective to
maintain the speed. One of the most common mistakes made
on loops is using too much negative (–) collective at the top.
Flips: Be certain to start with plenty of altitude. From an
upright hover slowly add in full forward cyclic and as the
model approaches vertical bring the collective stick back to
center. Now as the model continues to inverted you will need
to start adding in negative (–) collective (or pull the collective
stick back towards yourself). As the model transitions back to
vertical again bring the collective stick back to the middle and
start adding in positive (+) collective as the model returns back
to upright. It’s simply a matter of timing. The most important
thing is, do not throw the sticks around as this can cause the
head speed to drop and may cause the tail to drift.
Inverted Hovering: Keep in mind fl ying a helicopter inverted
is very diffi cult but can be learned. One of the main problems
is 3 out of 4 of the controls are reversed (forward/aft cyclic,
collective and tail rotor). You have to mentally reverse these
while fl ying. It will take some practice.
Take the loop you learned above and just hold the inverted
portion for short periods of time. As you become accustomed
to the reversed controls, you will extend the time inverted. It
is very diffi cult and will take some practice. Also, make sure
you have plenty of altitude for recovery if needed.
MAINTENANCE & REPAIRS
E-BOARD ADJUSTMENTS
Note: All of the e-board adjustments are pre-set and test
fl own at the factory. If you replace the e-board with a new
one or need to re-adjust it for any reason, please follow the
guidelines below. Never turn these adjustments more than
180° and only use a plastic non-conductive screwdriver to
make the adjustment.
Tip: If you need to make adjustments consider using a
felt-tip marker and place a mark on the adjusters so you
can always return them back to the factory defaults.
Left/Right Bias: Is used to obtain a balanced feel between
left and right tail rotor inputs. The adjustment is very sensitive
so only make small changes. Turn clockwise to increase the
left tail rotor bias.
Gyro Gain: Turn clockwise to increase gain. Typically too
little gyro gain causes the tail to slowly move around and
drift. With the gyro gain too high, you will notice a very fast
oscillation in the tail known as “wag.” This adjustment is not
very critical so please don’t spend a lot of time trying to get
”the best” setting possible.
Tail Rotor Trim: If the helicopter wants to drift one direction in
a stable hover then try using this adjustment. The adjustment
is very sensitive so only make small changes. Turn clockwise
to add right tail rotor trim.
