application problem of NER-102 receiver
Hi everyone:
I have a radio car using PYTHON pistol transmitter and BEC NER-102 receiver which is wired to MC 210CB speed controller. Everything is running fine. Function port 1 of the receiver is used to the steering servo, function 2 port of the receiver is used to the speed controller which is wired to motor.
I tried to switch the wires of function 1 and function 2 ports. The effect is funny, but it works like what I expected. The gas trigger on the pistol transmitter controls the steering servo, the steering dial on the pistol transmitter controls the speed of the motor.
But the problem is that the steering servo just does not work whenever the speed controller is unplued(I mean function 2 port is empty).I am thinking a new application of the receiver, I actually only need this receiver to control one servo. That is why I need to unplug the speed controller.
Can anybody help me with my problem
Thank you very much
ok. Let me give a short version of my problem as followings:
It seems the steering servo
just stops working whenever the speed controlor is unplugged from the receiver.
Does that mean this particular receiver is designed to only control both steering servo and speed controler the same time.Whenever one of these two devices is unplgged, the receiver just stop working.

The speed control normally supplies power to the receiver and steering servo. You need a receiver battery for your situation. Radios typically come with a 4 cell AA battery holder, or you can buy a rechargeable receiver packs at any hobby shop. Nitro and gas powered vehicles use them for example.
4.8 to 6 Volts typically, 4 alkaline cells or 4 to 5 nimh rechargeable cells. Some people are now using 2s lipo, but not all receivers and/or servos cope well with the higher Voltage. Typically the receiver has a battery port, but they can go into any channel, just be sure to match up the position of the red/black wires.
The rechargeables come in a variety of capacities, the mAh rating, that just means how long they would last before needing recharging. You can use any size alkaline similarly, C or D size would just go longer for example.
Am curious, what is your project?
