Speed setting precautions

• When the speed setting channel travel (EPA, ATV, AFR) is set to 20%

or less, points 1 and 3 cannot be set.

• The engine maximum speed range limits the maximum speed setting.

• Test ﬂy the helicopter with the governor turned off and tach the main

rotor R.P.M. while in horizontal ﬂight. This is the maximum R.P.M. that

can be achieved with the engine and pitch setup that you are using.

Please set the governor maximum speed to approximately 50 R.P.M.’s

less than max R.P.M. (Example: If 1800 R.P.M.’s is max, then set gov-

ernor to 1750)

• The maximum speed can be veriﬁed at the MAX. speed display. How-

ever, this value could reflect an unlocked main rotor condition and

would thus be inaccurate.

WARNING

Always level the swashplate using the cyclic stick before applying

throttle and spooling the main rotor blades up. During takeoff small

corrections may be necessary. If you make large corrections while the

helicopter is on the ground, it may tip over since the helicopter is ﬁrmly

on the ground and the gyros are overcompensating due to the lack of

movement.

Some helicopters may have a tendency to resonate/shake during

spool up. Always leave the helicopter on the ground until this reso-

nance or shaking goes away. If this issue continues, it is recommend-

ed to try some rubber skid stops or take off from a softer surface such

as grass. Vibrations contribute to this ground resonance. Verify that

everything on your model is balanced correctly.

PERATION

WARNING

Safety reminder: Remember to conﬁgure your transmitter fail safe

settings for not only the throttle channel but also governor ON/OFF

channel to ensure the governor correctly disengages should the radio

enter fail safe.
