AIRTRONICS RDS8000 2.4 - THE ONLY WAY TO FLY!!

[jetjockey69]

I fly both large 3D gassers and all carbon/kevlar molded gliders. I've been following threads on a lot of the glider sites regarding the trials and tribulations of using the JR / Spektrum stuff, and reading up on the experiences of the jet crowd.

Well, after a ton of reading and research, I've decided that Futaba and Airtronics is the way to go for me, because I think that freq hopping seems a bit more reliable (just my humble opinion), and having to deal with extra little Rx's is a hassle to me. I like that I can also extend the antennas on the Futaba and Airtronics Rx's, and only have to make sure that the little bare ends are clear of any carbon or metal and oriented 90 deg to each other. With the new 10C, I think Futaba may finally have something to compete with the JR9303 for those of us who like to fly gliders! The programming on the Futaba radios has always been my complaint, but I think I'm going to go for it with the 10C, and I'm also going to pick up at least one Airtronics RDS8000. Man, that has got to be the most radio you can buy for that price, hands down!

Now, my big question is: is Airtronics going to offer some smaller Rx's (fewer channels) that will work with the RDS8000? And second, what Rx's are compatible with Futaba's new 10C and 12FGA?

I only wish that Multiplex still manufactured and supported the Profi 4000 radio and offered it as a dedicated FHSS system. I would be in hog heaven then, cause that radio is still the most versatile and capable radio I've ever had the pleasure to use.

I trust/like Spektrum over FASST

[DC Gayhart]

How do Faast and Airtronics handle the Multipath issue? I have read many tech docs and that seems to be one of the biggest problems in the higher frequencys. With such a short wave lenght you need multiple antennas spaced more the a wave lenght apart. The wave length on 2.4GHZ is just over 4 inch.

REDUNDANCY! REDUNDANCY! We all load our planes up with dual rx's dual batt's etc... i love the idea of several remote rx's in function together. i love the idea that line of sight is covered by all angles. i use the jr 9303 and fly specktrum 9000 and 9100 rx's. i am COMPLETELY satisfied. i used the spektrum DX-7 for a while and really enjoyed that radio but needed the flight mode capabilities that come with the JR. my father flies FASST (long time futaba guy) and he is completely satisfied with that. their one rx is working fine in dad's 30% stuff. i fly 42% ers and i want as much rx redundancy as i can get just to protect the thousands of $$$$$$$ in the air!

Ok Spectrum 2.4 guru's I have a question to post. Today had a good first flight,non eventfull.Second preflight ,I turn on TX,turn on RX, do my surface checks,all OK,flip the engine to choke,turn off choke,ign. on ,fire the engine ,do a short run-up,still OK,then throttle goes to full and I have ZERO control,did not even go to fail safe,which is ign. off,choke on throttle at idle.We get the plane shut down,every thing is booted up,but do not have a bind.We do a battery check,6.9v with a 3amp load on both batteries,do a rebind and everything seems to be ok,WHAT THE HECK WAS THE CAUSE for this ,need help and imputs please,thanks Donnie

Here is how I bind my JR Spektrum receivers. I have not had a problem since doing it this way.

1. Bind the receiver
- Insert bind plug into receiver
- power on receiver
- turn on transmitter with bind button pressed on back
- remove the bind plug and power off everything
2. Set the servos, throws and everything else like you would fly the plane.
3. Rebind the receiver (see step 1)
4. I do one more rebind except ..
- after I power up the receiver I pull the bind plug out.
- Then I turn on the receiver with the bind button pushed.
5. I power everything off..turn it back on and test fail safe
6. Turn it all on..hold all sticks at full deflection and turn off the transmitter with everything fully deflected. If you did this right as soon as you turn off the tranmitter all surfaces should return to neutral and throttle should be fully closed.
7. Range check
8. Go fly

Pepa, I will do you're re-boot today.
Thank You

its simple really,
Your old bind had the throttle reversed, it will always go to where it was bound. the throttle channel is the only one that does that besides the gear will initialize in its bound state.

you probably had the transmitter too close to the model. set it behind you a few feet away.

You probably did not have a power issue on this one, its likely a swamping issue. I have several posts on the issue. I have seen holds cause this. It is possible you didnt even link it fully. You need to get into the habit of checking for full system connect before firing up.

tx on, wait 10 sec. Rx on. wait......let it link. check the receiver if you can for a solid light. check the controls and go.

When you bind it the next time, just do it by the book, and make sure the throttle is in idle setting you want.

When you are all done binding, power up everything and go full throttle. turn off transmitter and it will go to idle. If it does not, then you didnt have a successful bind.

Binding is so simple. just put the plug in, power the rx, it blinks
hold the bind button and power the transmitter and hold until lights go steady on ALL receivers. Pull the plug and power down. you are done. dont do all that other stuff its a waste. If it wont bind like that, something is wrong.

When you bind, move away from the model about 10 feet or so to do it so to get a clean signal.

Spoke to a technician today at Horizon ,was told to send the RX back,there is definitely something wrong in the RX.

goose f22...

i was having a problem getting all of my remotes to stay bound at the nall and a gentleman helped me from horizon. he actually had me power on the rx (bind plug in) then remove plug as rx's flashed and THEN power on the tx and hold til steady lights... he called it smart binding. make any sense to you? i use the 9303 and this particular rx was a spektrum 9000 with 2 remotes..... it worked great and has held each time like that since... just wondering about your input....

that is smart failsafe programming. that allows you to pre program the other controls other than the throttle to low. Yes that works too. Its described in the manual.

sometimes that works when nothing else will. I havent experienced that first hand before but have heard of it. Usually if one antenna wont bind, its a software compatiability according to my experiences and the ones at the lab.

thats the way to program it if: lets say you want your gear to come down if it goes into failsafe, and maybe a little rudder to make it circle or something like that.

Im going to do my jet that way this week after I finish reprogramming it.

Any news of any such on the horizon? I have been waiting for this technology to appear commercially and to mature enough so that it's useful for my turbine jet projects! Keith

The Multiplex 4000 is also my favorite radio but also probably the best radio of all time and you can look here for a 2.4 module
