Connecting my futaba controll system to hotshot

[will04 0]

I'm trying to connect my Futaba radio controll system (FP-2GS) to my vintage Hotshot mechanical speed controller. On step 23 of the original instruction manual it says to cut off receiver connector as shown and connect the receiver connector to the speed controller switch wires (red to red and black to black) the problem that I'm having is my futaba reciever has a red,black,and white wire so what do I do with the white wire? ( the speed controller has a red and black wire and the reciever connector has a red,black,and white wire)

I don't have a vintage HS manual around, but rather than cutting, can't you just plug the switch into the receiver? I assume from your description that the FP-2GS Rx is one with wire bundles coming out of it rather than sockets on the Rx body? If that is the case, the sockets on the end of the wires should be regular Futaba type. There should be three bundles total, two of them with a white wire as well as the red and black, along with one which only has red and black. If you can post a picture of the Rx that will help a lot! If you can see my picture, the MSC is plugged directly into the Rx, however that Rx has sockets not wire bundles.

Where your connector is plugged into the battery slot on your receiver, my plug has a white wire as well and I have to use the original connector as the little metal prongs are on the connector not the reciever ill try and post some pics

The red/black wire should be connected to the BATT connector of the receiver. This can have a switch in the circuit, or without. Without means the receiver is on when the battery is connected.

This 2 pin reb/black lead from the ESC is there to power the receiver (vintage style BEC so you don't need 4x 'AA' cells to power the receiver). You need to plug a servo for the steering into CH1, and connect a servo in CH2 for the MSC position arm. The servos have 3 wires. Red is +ve, black is -ve and white is signal.

If the receiver is the one I think it is, I cut the 'backwards' connectors off the end of mine and soldered on some modern ones so I could use more modern servos and BEC connector for the BATT.
