we talk about UAV technology on the foremost common RC on the shop that have all newest drone technology. Most RC can have terribly similar systems incorporated. Pilotless aerial vehicle technology covers everything from the mechanics of the RC, materials within the manufacture of the physical UAV, to the circuit boards, chipset and software package that area unit the brains of the drone. One in every of the foremostcommon drones on the market is DJI Phantom 3. This drone was very popular with professional aerial cinematographers.
This could be an airleak after the airflow meter, any expose dragged in here isn t seen by the ECU and in view of that not compensated for and can thin the engine out and can then permit the engine to rev taking place similar to not desired causing rude running. As its a mechanical oddity it tends not to tilt on the defect buoyant and you can sometimes hear a hissing noise past the engine running.
I did re-check them tho. The master tech did extensive tests upon the ventilate flow meter and said it was good. subsequent to I unplug it and govern the motor, the car runs severe and at 850ish. I can deserted guess that my extra rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of every this. I don't think the tps has that much manage in the alternating of rpm though? I think it only adjusts it approaching 1k..
I'm reviewing your question now, and will herald incite subsequently your answer ASAP. Rgds Greg. What fault codes reach you have. Does the engine control later than the MAF disconnected. past the noisy hissing sealed this could be your problem. This could be a large vacuum leak ,with the MAF amalgamated it is deserted measuring the expose that is getting as soon as the MAF, in view of that if the intake manifold is sucking in air the ventilate to fuel ratio will be completely out and cause the engine to stal
