Connecting Servos

Recommended Posts

Hey,

I was wondering if you folks have ever had the problem of having only 6 channels on your reciever, and only 2 channels spare with about 7 things you want to control?

Well I was wondering if it is possible to hook up two or three servos together into one slot, aka hooking them up so that one channel controls those servos. Basically at the moment I want one of my channels to drop my flaps and tail hook together at the same time.

I am sure you have hooked up more than one electrical applicance to one plug, because you only have one wall plug in your room.

Can it be done, any side effects etc?

Well, that's why Y-cables exist! You can connect multiple servos to the same output, the only thing is that they will all move the same! :)

Often used for aileron pairs, flaps,...

Hey,

Thanks for your replies, I was wondering where you could buy the Y cables, preferably in the UK or if a UK link can't be found or known, could you pass along the link of the US site that supplies, I apologise for the rather stupid question.

Any model shop in the UK will have them but they are pricey for what they are !

You can also buy the components i.e. connector shells and contacts for e.g. Futaba plugs and sockets. If you can drive a soldering iron you can then make bespoke cables to suit your needs.

With regard to connections to detachable items like wings. I normally always use two servos for ailerons and if flaps were to be fitted another pair as my aircraft tend to be on the larger size e.g. 80" span. In these cases I actually cut the servo cables off with approximately 3" left on the servo. I then extend the cables sleeving each wire with heat shrink at the joint. For the connection between the wing and fuselage I use a male 9 pin D connector again carefully sleeving each pin. The servo connectors removed from the servos are then wired to a female 9 pin D connector which is mounted at a convienent point in the fuselage to enable the connections to the receiver to be made. When the model is assembled you the only have one easy connection to make rather than two or four and you can't connect the wrong cables together. If you adopt this idea I recommend that you set up a wiring convention and then use it for all of your models.
