Spektrum Serial Receiver with PPM, SRXL, Remote Rx (SPMAR7700): Spektrum
Simply choose two batteries of the same size and capacity with two switches.
When you get your speed controller it will not have all the connectors necessary to hook everything up so you will need to pull out your soldering iron and heat shrink and get to work! You can 'half plug' the two connectors together and make sure that the red and black wires match.
Could you please suggest what should I select in the receiver type for Flysky i6, many thanks in advance.
Regardless FrSky has a gamut of different sensors and you can program the radio to do different things with the information.
Holds: In the rare occurrence your system encounters 45 consecutive frame losses, a hold will be triggered.
That will affect the threshold and might cause it not to work, so try the software serial for your input and so use another pin.
