AEROBATICS
So you are getting comfortable in fast forward flight? Well, now it’s time to slowly
progress into aerobatics. Your AXE100 SS/SSL is more than capable of full
aerobatic performance. Once you are in forward flight start using the idle up
switch. This switch raises the rotor RPM and allows the blades to progress into
negative pitch for aerobatics and inverted flight.
Chandelles: Your first 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. 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. This can cause the head speed to drop and
may cause the tail to drift.
Inverted Hovering: Keep in mind flying a helicopter inverted is difficult but
with practice it 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 flying. 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. Also, make sure you have plenty of altitude for recovery if needed.
