Hi to all users of Airmaster Constant Speed Propellers,

 

Aside from benefiting from other more experienced users feedback/tips, I would like to address what I see as an operational anomalie in my unit, namely the failure to maintain an Auto Cruise constant prop speed.

Whaaaat! No Airmaster users in the whole Forum????😈

The constant speed auto function is only functional while in Auto mode Hold selected between 5700max and 4000min on a 9XX motor.Pg47 POH.

 

Auto Hold will return to last Hold speed setting until power off reset to Cruise at next power on. Manual adjust of Auto Hold speed is only affected via manual pitch adjust switch while both Auto and Hold are selected simultaneously.

 

Section 9.2 Indications - LED signal colours and interpretations. Pg48/49

 

Section 9.3.8 Loss of Speed Signal - Failure of controller to drive pitch control. No LED fault indication at AC200. Pg 52

 

ANNEX B AC200 Controller, Sensor Brush Cable Pin Outs - Pin #1 Speed Signal Input, magnetic sensor. Orange/White. Pg70

 

Check you speed sensor circuit for loose or dirty connection.

Thanks Area - 51.

 

Problem (if its not the operator) is likly a tad more complex. May require controller be returned to Airmaster.😈
