Can anyone direct me to a resource on connectors used in electric RC? There seem to be so many that it's difficult to keep track of and know what exactly is compatible with what. For example, will any servo connect to my Futaba receiver? Will any battery pack?

Thanks!

Most connectors do fit,,be careful though, some of them will fit if you trim the tiny trim piece off, but if you do that you need to mark them as they will also fit backwards...and it takes about 1 second to fry an ESC on an electric plane...yes I did it....I've always heard of Deans conectors but I have no idea why people use them as opposed to the stock connectors?...Rog

Deans Ultra allow more amps... If you're running alot of amps you can fry some stock conectors (ask me how I know).

However, I have no idea why you would use a Deans conector for a reciever pack....

Good luck, Laggard. Trying to sort out the confusing variety of electrical connectors used by various manufacturers will keep you busy for some time.

A lot of manufacturers ship batteries and speed controllers without any connectors at all. You're expected to be able to choose the appropriate connectors, solder them in place, and protect the solder joints with heat-shrink film before you can run your aircraft.

I have a bad habit of using Electrifly setups as recommended by Tower Hobbies. I know there's better equipment available, but if I buy an Electrifly motor, speed controller, and battery, they'll all come with the necessary connectors to hook up to one another.

Virtually any servo/battery/wiring/switch will connect to the Futaba RX. It is in fact the Futaba plugs that have the little tab mentioned above which may need to be removed if used with OTHER brands. You do want to watch wiring polarity on SOME servos.

As to the connections for servos there are a few little differences. Most any servo will work with any receiver, it's just a matter of making sure the plug and wiring are correct. Refer to the attached diagram to see what you need to do to connect to your Futaba.

On both Futaba and JR servos, the "hot" wire is in the center so if you put the plug in backwards, the hot wire is still connected to the correct terminal, only the signal and ground are interchanged which does no damage. The servo just doesn't do anything. It's Airtronic servos that you have to be carful with. They insist on haveing the hot (+) wire on an outside terminal. These have to be rewired before using them on a Futaba or JR RX. High Tech and most others use the JR system.

As far as battery connectors are concerned, I personally have standardized on Dean's Ultra Plugs on all my e-planes, even though they are overkill for park flyers. That way one charger can handle everything. I think they are good for up to about 100 amps.

Thanks for all the helpful info. One thing I don't understand are these type receivers:



I only see what appears to be one or two pins for each channel. How does that work?

I don't know about the others but I can't see your link/picture. What RX is it?

Can you see it now Bruce??

No, just a small square with a red X in it. This has happened before and I was able to see them at home so I'm sure it's something in (or not in) my computer here.

One of these? I see three pins per servo.

you can go to cheapbatterypacks dot com and build your own pack, and the last part of the build is what connectors they have available in pics ..if you just want to see what different ones look like...Rog
