Is this a good product for someone who's new and going to be getting 4 new planes... it seems to be from the 80's and what's a fair price to offer?

It's a good radio, but not for multi models. It's not computerized and does not have multi model memory which means you will have to reset the reverse switches, trims and throw rates every time you fly a different model. At some point, the inevitable will happen and you will forget to set one of the many switches and will end up crashing a model.

I also noticed that both you and the person selling the radio on Ebay are in Colorado. I know it's a pretty good sized state but I hope you and he are not one in the same. Advertising Ebay items on this forum isn't exactly following the rules.

Thanks for info...

Yea, you're probably right about the switches etc. That would be something i'd do. But if i could pick it up for $50 bucks or so do you think that's a good deal?

No i'm not the same... i have no idea where evergreen co is

Also.. i have another question. I just bought four planes and a whole bunch of goodies. Inc. was a Futaba Conquest t6NFK 6ch. It's pretty old i suppose but it didn't have any instructions with it. What does the "trainer switch" do? Is that for hooking up one of those cable things and making it a trainer box? Also do you have to have same boxes to do the trainer/buddy box thing? Do all futaba's work together? If so should i get a Computer Futaba and use this as a trainer for my son?

For $50.00, yes it would be a good deal as long as you understand you will more than likely need to replace both the transmitter and receiver batteries due to age. Figure this to cost about $50.00-$60.00 on top of whatever you could buy the system for.

A trainer switch is used to electronically hand off the control of the aircraft to another transmitter connected to the primary transmitter through a cable. Yes, the two transmitters need to be of the same manufacturer. AM Futaba's work together, but not with FM Futaba's and vice versa. No, a Futaba transmitter will not work with the JR. They use a completely different style plug.

One other thing. Century 7 radios use lots of metal in their cases... they are sturdy (understatement!) but weigh a *ton* when compared with most of the newer offerings.

I had two of them. One died due to corrosion, the other one developed a short somewhere internally and stops transmitting RF when held at a certain angle. I used it as a buddy box for a while, but have shelved it as its too damn heavy!

You'd be better suited by getting one of the inexpensive 6-7 channel computer radios. You can save some $$ by picking up one here on RCU - there are always folks looking to sell off their old radios when they upgrade.

As mentioned above the C7 isn't a multi-model radio. Resetting switches and retrimming every time you fly another plane is a pain. At some point you'll probably end up purchasing another radio to replace (or supplement) the C7 - and where are the savings in that?

However. If you can get that package for around $50 bucks I'd take it. $25 bucks apiece for two brand-new 7-channel receivers is nothing to sneeze at
