I need advice on be best way to operate an Mt electric prop in order to avoid over speeds. Referencing the manual...
For go arounds high airspeeds should be avoided because an overspeed may occur. The rate of pitch change is only 1°/sec and therefore slower than with hydraulic constant speed propellers. It is recommended to reduce airspeed to the best rate of climb speed before take off power is set.
The same thing will happen in a loop. If I have full throttle set and 2500 rpm in auto mode, as the airspeed decreases over the top the blades adjust to hold that rpm, so as the airspeed increases on the backside it can quickly over speed unless i keep the power all the way back at idle. It is difficult to do another maneuver back to back because I have to wait for the pitch to change back in order to push the throttle up.
Would it be better to just switch to manual at the loop entry airspeed 140-160 at 2500 rpm? Does it just act like a fixed blade prop at that point? What would happen over the top as the airspeed decreases to 70 kts?
