ENGINE GOVERNOR SETTING
引擎及定速器設定
3.“ Lock ” on condition“鎖定模式”啟動條件
The governor function will be on when the throttle stick is at 25%+ position, as well as the actual RPM of engine reaches
80% of the setting RPM. The LED indicator lights steadily on in red when the actual RPM is /-1% inaccuracy. The
LED indicator starts to flash if the inaccuracy e/-1%.
定速鎖定模式僅會在油門撥桿大於25%或引擎RPM達到設定轉速值的80%以上時啟用。啟用後，RPM會維持在誤差+/-1%以下，此
時LED指示燈為紅燈恆亮。當RPM超過1%誤差時，則LED指示燈會呈現閃爍狀態。
4. Throttle curve setting 油門曲線設定
If the Zero α II fails, it will give control back to the throttle curve. Therefore, it is recommended to setup a backup
throttle curve. The simple linear line can be used for normal flight. However, a V curve is needed for idle up mode and
the valley must be higher than 25%. The throttle curves in right are
recommended in case the governor malfunctions.
若定速器失效時，油門將直接對應油門曲線，因此建議您仍需設定油門曲
線。一般正常飛行使用時，可簡單地設定為一直線，若為特技模式，則建
議設為V曲線，但最低點仍應高於25%。右側油門曲線範例提供您參考。
5. Pitch curve setting 螺距曲線設定
The pitch curve setting is similar to without the governor. The difference is that the maximum pitch must be calculated
to maximize the governor effect. To get the max pitch, fly the helicopter in the lock mode and max. throttle. If the LED
light steadily illuminates, increase the pitch setting angle until the LED temporarily extinguishes. Reduce the pitch setting
a little bit from this point; this will be the max. pitch setting for the max. engine power output.
螺距曲線設定與未安裝定速器時大約相同，唯一不同的是最大螺距必需配合定速器的效能。請先在鎖定模式下將以最大油門飛行，
來決定最大螺距。若LED指示燈持續恆亮，請加大螺距設定直至LED短暫熄滅，以此時的螺距值再減低一些，就是符合最大引擎動
力輸出的最佳螺距設定。
6. Gain Setting 感度設定
The governor gain controls the response time. If the user feels that the response is too
slow or if the engine overspeeds, a clockwise turn of the gain adjuster will speed up the
governor’s response. On the other hand, if an unstable or hunting situation is found, a
counter-clockwise turn of the gain is necessary to reduce the control response.
定速器感度值可改變反應時間。如感覺定速器反應略為緩慢，或引擎有超轉現象，可順時針旋轉
感度值設定鈕來提高定速器反應速度。相反地，若定速器穩定性略差或發生不斷修正的現象，可
逆時針旋轉感度設定值鈕至所適當的位置來獲得改善。
■ Flight test 飛行測試
For the first flight after installing the governor, be sure to start the engine in the Unlock mode. After lift-off under
control and without any abnormal conditions, switch the governor into Lock mode. The flights will be similar to without
the governor. The only difference is that the engine will be locked at the recommended RPM setting in the Lock mode. If
there are any abnormal conditions, switch back to Unlock mode immediately and land the helicopter. Please check all the
governor setting procedures and do the flight test again. After a successful flight test, the helicopter can take off in
either Lock or Unlock mode. This mode can be switched back and forth between Lock either or Unlock during flight.
When Lock mode is engaged, the LED will become a steady red from the flashing red after a short period. The steady
red light indicates that the governor already has maintained the engine RPM within 1% error of the setting RPM. During
normal maneuvers, the LED will be steady red. The LED may temporarily flash then return to steady red during violent
maneuvers. It is normal for the engine to require time to respond to the control command.
安裝定速器後首次飛行時，請務必在非鎖定模式下啟動引擎。起飛後，若操作一切正常且無任何異常現象，再啟用鎖定模式。所有的
飛行操作方法與未安裝定速器前一樣，唯一差異僅在當啟用鎖定定速模式時，引擎轉速將被控制在所設定的RPM值。此時，若有發
現任何異常，請立即撥切至非鎖定模式並停止飛行，並依前述“操作模式設定及調整”重新確認所有設定步驟後，再進行飛行測試。
成功完成飛行測試後，直昇機才可以鎖定或非鎖定模式進行起飛，飛行時可自由撥切設定開關為鎖定或非鎖定模式。當啟用鎖定模式
時，LED會在一段時間的短暫閃爍狀態變成恆亮，此時表示定速器已將引擎維持控制在所設定RPM值的1%誤差以內。一般正常飛行
時，LED指示燈為紅燈恆亮；當執行極限特技飛行時，有時LED指示燈會短暫出現閃樂紅燈後再恢復為紅燈恆亮，這是因為引擎需要
時間來反應定速器控制指令而出現的正常現象。

CAUTION /
警告
To start the engine to do flight tests is necessary. Therefore, it is strongly recommended to seek helps and
guidance from accomplished pilots if you were a newcomer to the RC helicopters!
進行飛行測試必需啟動引擎，如果您是剛接觸模型直昇機的初學者，我們強烈建議您尋求有經驗的玩家給予協助及指導！
