The Walkera Master CP helicopter has an unsafe flaw in the receiver firmware. When the throttle stick is lowered quickly or when the throttle hold switch is activated, there is greater than a one-second delay for the receiver's throttle signal to turn the motor off. This is a concern about safety andminimizingdamage to the helicopter in a crash.
We the undersigned Master CP owners understand the great helicoptersthatengineers at Walkera design sometimes have problems in the released versions. Upgradeable receivers in recent models is a very bold step in the right direction and we customers applaud this feature. Next, issuingtimely upgrade firmware for your products would take Walkera aheadof the competition. Please fix firmware bugs soon after they are discovered. Thank you.
