we discuss UAV technology on the foremost widespread Drones on the shop that have all the most recent drone advanced. Most RC can have terribly similar systems incorporated. Pilotless aerial vehicle technology covers everything from the aeromechanics of the RC, materials within the manufacture of the physical UAV, to the circuit boards, chipset and software system that area unit the brains of the drone. One in every of the foremostcommon drones on the market is the DJI Phantom 3. This drone was very fashionable with skilled aerial cinematographers.
This could be an airleak after the airflow meter, any air dragged in here isn t seen by the ECU and fittingly not compensated for and can lean the engine out and can as well as permit the engine to rev in the works when not desired causing brusque running. As its a mechanical deviation it tends not to slant upon the fault well-ventilated and you can sometimes listen a hissing noise bearing in mind 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 do a fast oddity find if you unplug the meter and govern the engine without it. if the engine condition is the same next chances are the meter or the attachment to it is faulty. Its furthermore worth cleaning the MAF sensor wires, as they can get coated afterward dirt on top of grow old which after that offsets the reading. Use some entry cleaner or brake cleaner to spray onto the wires to cut off the dirt upon no account touch the wires in the manner of whatever as they are completely fragile
This could be a large vacuum leak ,with the MAF amalgamated it is unaccompanied measuring the air that is getting gone the MAF, thus if the intake manifold is sucking in air the let breathe to fuel ratio will be unquestionably out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. subsequent to carb cleaner spray can spray in the area of the hissing like the engine doling out and with you hear the engine stall or rev unconventional there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
