Help!
Which radio shall I get for a quadcopter?

Hi! It looks like we're just about to get our first quad, probably the Gaui 330x. I'm trying to figure out whether it's cheaper to get a full kit, including radio, on Ebay, like this one:
http://cgi.ebay.com/GAUI-330X-S-Quad...item33660c16bd

Or whether to get the kit alone and get my own radio.

I'm somewhat dazed by all the different Tx/Rx kits out there; just looking for "Futaba 2.4GHz," Buy It Now, brings up a price range from 90 to 300 USD, and different labels--mode 2, mode 1, airplane, heli, indoor, sport, Fassst...will all of them work with the Gaui?

I'd appreciate your help greatly!

Nathan

If you are serious about quadchoppers and someday want to get one with GPS navigation you will need 8 or more channels.

The Futaba 8FGH that has a free firmware upgrade to 14-channels is my favorite best deal. The Hitech 9-channel and DX8 are also very popular. If you get the DX8 make sure it’s the DSMX version and not the obsolete DSM2 version.

You want mode 2 so that the stick represents the movement of your quadchopper. Be sure and get a helicopter version as it had a smooth throttle that’s required for hovering. The throttle ratchet on airplane transmitters makes it almost impossible to fly a chopper.

All receivers have the same servo interface so compatibility is not a problem. The only restriction is that the receiver has to be compatible with the transmitter. That usually means it has to be the same brand but there are a few exceptions.

All DX8s are DSMX compatible. I think the very very early production units need to be sent in to the factory for the upgrade, but anything you find on shelves today is most likely upgradeable yourself via the SD card--if it doesn't have the new firmware in it already.

Thanks to both of you for answering such a newb-y question. Some of the terms are still obscure to me (Fasst [or is it fassst?] vs fhss for example) but in general I think I have an idea of what to get now.
As far as I know the Gaui 330x I'm planning isn't upgradable to GPS yet; do you still think it would be better to invest in an 8CH radio rather than a 6? I'm trying to save wherever I can, but maybe this wouldn't be saving in the long run if I get a better quad later...I don't know.

Nathan,

Always buy as much radio as you can afford. Eventually you'll need it and you won't be sorry if you buy something that you can grow into rather than grow out of. If you decide to get out of the hobby, higher-end products hold their value better. Either way, you are better off for buying the better product.

It applies to more than just radios - always get the best you can.

The transmitter is potentially a long term investment. If you are not sure about staying with the hobby you might limit your risk by going for something like a DX6i. But if you stay with it, you'll be wishing in a couple of years that you had gone for the added flexibility of the DX8 or similar. It's not just a matter of number of channels. The programming flexibility is far greater for the DX8 than for the DX6i and it has essentially unlimited numbers of model memories instead of just 10.

But in the end only you can assess the respective risks of underbuying and overbuying.

Well thanks, Andy, Daedalus--I'm convinced. Now I just have to convince my fellow investors
I heard Futaba has an 8 channel upgradeable to a 14? Do either of you know anything about that model?

I have an 8FGH that I upgraded to 14 channels about a month ago. I use it for multi rotor (Quad and Y6), airplanes and helicopters. All the new 8FG series of radios will have the 14-channel upgrade installed and they will be called the 8FG Super transmitters. If you find an old one in stock all you have to do is download the upgrade to your PC. Copy a few files to a SD card (instructions on Futaba web sight) and put the SD card in the transmitter. You flip the upgrade switch and turn on power and it does the upgrade for free. That’s definitely the best deal on the market today.
