If it's a 2-channel reciever there is only one place to plug it in. If it's a 3-channel RX like what most of the FM RX's are nowadays you can either plug it into the regular receptacle which will be at one end but a tip if it is a 3-channel RX with BEC. Plug the battery pack into the open servo plug and you can pump more than the 5 or 6 volts that the BEC will limit it to.

Alex, I'm not an Airtronics expert, but from your description it sounds like you have a 7 channel airplane receiver that was shipped with a channel 52 crystal. Does the little fuse like thing (probably the crystal) with the number 52 on it happen to have 72.830 somewhere on it? If not, what number does it have?

You should look for a similar thing on the transmitter and look for a number on it too. The crystal number on the transmitter and receiver need to match. However, the crystal also needs to be in the proper range for the equipment it is installed in. It appears your receiver is for the 72 Mhz FM range. Your transmitter is for the 75 Mhz range. The 75.850 number corresponds to surface frequency 83. Since crystal swapping is common among some groups you need to find the transmitter crystal and see what number it has.

To answer your original question, the battery can go in the 7/b slot, but unfortunately, that's not going to do much good.

I suggest contracting the seller and asking for the correct receiver.

It sounds like you've got a mixed package there! If it doesn't work, I can see why! A Futaba transmitter, much less an AM one, shouldn't work with an Airtronics 7-channel FM aircraft reciever. One is a positive shift system, the other is a negative shift system. Somebody unloaded the completely wrong radio setup for the boat.
You can spend another $50-75.00 and get a complete radio system that will work in the boat.
That little fuse looking thing is the reciever crystal. There is another one on the transmitter too, it may be under a tiny cover.
I hope that you didn't leave that person positive feedback!

The problem with a lot of the radio manufacturers is that the reciever alone costs almost as much as buying a complete Attack radio system! Shocking but true. I looked into this myself when I was thinking of adding a matching reciever with servos, crystal and battery switch for my multi-memory transmitter.

I suggest creating auctions for them, set the starting price at $.99, offer a fixed shipping price that lets you make a couple $, and take whatever you get. After all, you didn't pay much for them, so anything is better than nothing. Keep in mind that since you don't have a matching transmitter, you can't test anything. This means the buyer is taking a big risk. It may work, but it may not. The servos, switch, and battery should be fine with a Futaba receiver.

You could check with Tower to see if something like this receiver:
http://www2.towerhobbies.com/cgi-bin...I=LXJB51**&P=0
is compatable with your transmitter. I've seen posts here that many of the Tower radio components are actually made by Futaba. The price $24 for receiver plus crystal isn't bad.

However, having said this, you still may be better off auctioning off everything and starting with a completely new radio. This way you will be sure that it's all working properly. In case you can't tell, I'm not big on second hand radio equipment unless I know the person I'm buying from.
