Hi everyone. Just finished a hobbistar mk111 60 using a Futaba 6EXA. Just bought a Giant super sportster with a Spectrum DX7 and servos for this sportster. Then I got to thinking. Wouldn't I be better off just getting the servos, battery, and receiver and use the same Futaba on a different model channel? I know that the DX7 has the new 2.4 GHz but for now wouldn't the other way work???? All input is apperciated. Thanks.

You've already got the DX 7. I'd consider getting another 2.4ghz receiver for your hobbistar. Set up your dx with a model program for each plane. Be sure you've selected the right plane before flying!

Sell the futaba and it's receiver to fund the new 2.4 receiver. All your servos will still work with the new receiver.

The other way would work too, but you end up flying an obselete transmitter (I do fly a 6exa myself) and the DX7 either gets sold or sits on a shelf. Again, it'd just be a receiver purchase, batteries, servos and switch harnesses are interchangable.

Since you alrerady have the DSM radio you should keep with it in the new equipment you buy. My personal choice is to stick with my JR 8103 and FM/synth gear. With all the other guys at the field switching to DSM it frees up the airwaves and good cheap recievers are easy to find as the new DSM guys are selling off thier old stuff. I have never fallen victim to FM interference and feel no reason to upgrade, infact, I have every reson not too.

Ok, there is absolutely nothing obsolete about about the 6EXA radio. 72 Mhz radios still work perfectly well and there is no reason to think there is. I have 72 Mhz radios that are 10 years old that I use all the time. I also have 2.4 Ghz radios as well. But there is no reason to quit using something because it's not brand new.

mitchsnap,
There is nothing wrong with setting up each plane on the two radios. Keep your original plane on the Futaba and put the new one on the DX7. Or you can buy a new receiver for the DX7 and program both of the planes into the DX7. Also, with the DX7 you can't fly with the wrong model selected because of the ModelMatch feature that these radios have. If you don't have the proper model selected it won't work.

RCKen, I know it's not really obsolete, but compared to a new 2.4ghz, it is "last generation". If I had one of each, I'd choose the modern one to stick with. One less battery to charge, if all use the same transmitter.

I've also got old radios I use. I've got a 7uap (think tha's right, 7 channel computer, 1 model memory lol) from 1988 I'm using for my Pipe Dream. It needs the 7 channels, due to bomb drops and such, while my 6exa runs the rest of the fleet.

You have 3 choices.
1.get another receiver for the Futaba (cheaper than a Spektrum RX)
2.get another Spektrum receiver
3. leave each plane as they are on seperate radios
None of the choices are bad and completely up to you.

Just thought it would be more economical for now being at a beginner level. Plus using a futaba buddy box would work out well too for now and other planes down the road. Just get another battery, receiver and servos for the futaba and return the DX7. Use the difference to fund the fuji bt-32b engine that I would like to put in the Sportster. Can always upgrade the electronics later.

My opinion:
I think you should return the DX7; the Futaba 6EX is a great radio (I have it) and it will keep you occupied for several planes in the future. If you couldn't return the DX7 it would be a different story, but you can get your money back, get another FM/PCM receiver, and save some cash (or buy something else that's really cool).

Good luck!

Thanks FatOrangeCat. I'm glad someone responded within my thoughts. All responses were great. I did not realize I could use the same transmitter radio with multiple planes. The maiden flight of the Hobbistar 60 was yesterday. A instructor took it up and did loops, barrel rolls, went inverted, and finally landed safely. It was awesome. Still working with the simulator and looking to pickup a buddy box for the futaba. Hopefully to take it up this coming weekend with an instructor. The futaba worked great. No problems. That's why I was considering to just pick up what I needed to get another plane in the air with the 6EXA. Once again, thanks to all responses. If there are other thoughts........ bring it on.

That 6EX you have has the capability to store the information of up to 6 planes, which means you can set up 6 planes and set the trims, and it will remember them all, so all you have to do is name the plane on the receiver, then select it when you want to fly it, and not have to set any trims. It has plenty of mixing capabilities for when you advance, and has the option of having exponentials set on the throws, as well as two settings, (high and low?) for response.

It will keep you occupied for a long time. Enjoy it!

Thanks again FatOrangeKat. I guess I will be returning the DX7 and getting what I need for the Giant Sportster for electronics for the Futaba and ordering the Fuji Imvac BT-32B.

There you go! Take some pics.

Just remember to mark your planes as to what model number they are on your radio. I am terrible for forgetting what plane is what model so I started marking the planes.
I like the Hitec Supreme II receivers with my Futaba @ $40 each plus $8 for a crystal they are economical but work just as well as any other receiver I have ever owned, including the $100 Futaba PCM receivers.

Luckily, the 6exa allows you to actually put names in for your planes, 4 characters. Better than some radios that only allow Model 1, 2, 3 etc.

Mine's programed for SRAY, AQUA, P51D so far... Do double check each surface, before each flight tho!

I love my "NXTR"!
