we talk about UAV technology on the foremost standard RC on the shop that have all the most recent drone advanced. Most Drones can have terribly similar systems incorporated.

This could be an airleak after the airflow meter, any freshen dragged in here isn t seen by the ECU and correspondingly not compensated for and can thin the engine out and can then permit the engine to rev up in imitation of not desired causing rasping running. As its a mechanical fault it tends not to perspective on the deviation well-ventilated and you can sometimes hear a hissing noise taking into consideration the engine running.
Might after that be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can get a quick anomaly find if you unplug the meter and manage the engine without it. if the engine condition is the thesame after that chances are the meter or the connection to it is faulty.

Use some admission cleaner or brake cleaner to spray onto the wires to separate the dirt upon no account touch the wires following anything as they are categorically fragile
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you happening to date upon every maintenance; spark plugs fuel filter pcv vlave etc? have you performed a visual inspection and listened to engine as it warms taking place and is warmed up? oftentimes in engine play in many factors may cause the same symptom(s)
