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 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.
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.
WHEN FLYING
If the tail wants to drift slowly due to wind gusts, your gain may be set too low.
Increase the gain a small amount and see if performance improves. If the tail has
a tendency to oscillate from left to right, your gain may be set too high. Reduce
the gain and see if performance improves.
