Hello, I bought Happymodel - 4 in 1 FLIGHT CONTROLLER for ELRS X1 AIO Drone. FC defective. Engine 3 does not turn well. with minimal power, the engine spins, when I give more power it stops spinning. I thought that the problem was in the engine, but after changing another one, the problem remains. and No. 3 engine is very hot. all others do not heat up. My friend has two flying drones with the same FC. We install the firmware as his. The problem hasn't gone away. I think this is a problem with the ESC mosfet.
A szállítással minden rendben volt. A kamera szerelési minősége jó, a videó színe és minősége teljesen rendben van. A kamera súlyát a 4 drónom meg se érzi, annyira könnyű. Ajánlott vétel, de GoPro minőséget ne várj tőle.
VTX gets warm over 90 degrees uncooled, when the VTX starts to get warm it rapidly regulates the power down. Passive as well as active cooling is necessary here to get the performance that is promised.
