I am a new beee, and have 2 raptor 50's and 3 trex's a 120 sr, a dx6I and a futaba 9tchp, what do I need to fly the trex's with the futaba t9chp which is 72 mhz. and the trex's are 2.4g. Which transmitter is better? I got all this stuff and a lot more( hell of a lot)on ebay. It was all in a storage bin the seller said.Thanks for the help.

DXi and the futaba are not compatable even if the Futaba is converted to 2.4. Might be worth selling off the DXi and getting the 2.4 module to convert the Futaba. What DXi do you have 5, 6 channel etc.

Re: Fuitaba 72 to 2.$ ghz convert?

"Better" is a very subjective term. The DX6i is 2.4ghz which means no interference, and you don't need to worry about shooting other people down when you turn your radio on if you fly at a club.

The Futaba is otherwise a nicer radio that'll have more features.

You probably want at least a 7 channel radio for the larger nitro helis - particularly if they use governors. 6 channels will be used up by the usual heli stuff, and you'll need a 7th to run the gov.

If you want to switch the trexes over to use the Futaba radio, then you'll need some 72mhz receivers and crystals to go with 'em. The crystal would need to be for the same channel as your radio.

Re: Fuitaba 72 to 2.$ ghz convert?

Tough call, but I would side with the 9C. It is a great transmitter.

Cost and your intended use will be the most important factors.

To go 2.4Ghz with the 9C, you will need a new module that plugs into the back in place of the 72 Mhz one.

Choices of Module/Receiver sets are many.....

Futaba uses the FASST system. It is a very solid link. You can get Futaba FASST or Orange FASST receivers. A 2.4Ghz module for your 9C will cost about $180 at a hobby shop, but I've seen them on eBay for as little as $90 brand new. Yes they work fine; I currently use an eBay acquired one. Typical genuine FASST receivers are $60 and up. No satellite receivers are required. A FASST compatible Orange receiver from Hobby King is about $28 and works fine in my 48" WS combat airplane for as far as I can see.

There are also other makers of 2.4Ghz systems such as Corona. Cost for complete systems are in the $40 range; maybe more or less...

Spektrum made a DSM2 module for Futaba transmitters but I haven't seen one available for a long time so I won't go there. Besides, DSM2 is on it's way to becoming obsolete, so maybe that's not a good path to pursue for your 9C.

Like most 2.4Ghz, The systems are usually matched. You cannot mix manufacturers like you could with 72Mhz.

I would suggest looking at your options. If you don't care and don't use BNF aircraft, there are cheap and reliable 2.4Ghz systems.

If you care a lot and don't do BNF than FASST is very good. It's a little pricey to get into but you won't ever regret it.

Unfortunately, Futaba, Hitec and Airtronics, etc have really missed the boat on equipment for small indoor type aircraft.

If you want to use BNF aircraft often or you already have many Spektrum receivers, you might find that a new Spektrum system is most affordable and versatile. Spektrum has really dominated the market for relatively inexpensive and feature rich 2.4 Ghz systems.

There is a healthy market for used 9C's.

Hope this helps a bit.

If you want to go 2.4 and be able to use BnF this is what you need for your radio Tx...


I have been using one since they came out and never had a problem.
