Status: offline 		I'm way behind on radio technology and need everyone's opinion. Here is my situation. I have 7 planes all .40-.60 size and 4 of them have 72mhz rx and the other 3 have spektrum rx. I have an old Futaba 9CHP 72mhz radio that has the spektrum module in it so I can switch over with ease. That way I can fly all my planes. Well my New Years Resolution is I want to totally convert everything to 2.4. Lot's of things factor in. I've always been with Futaba and never ever had any problems. If I get a new 2.4 Futaba radio would it be compatible with my spektrum rx's? I was also thinking about going with the Hitec Aurora 9 but I don't know if that one is compatible to spektrum either. I looked everywhere on the web and can't find a definite answer.

If you don't want to start buying Chinese clones, you pretty much have to stay brand specific.

Ok, I will keep you in mind. Probably not going to purchase a radio for another 2-3 weeks or so. I will PM you when I'm ready. Thanks

I'm way behind on radio technology and need everyone's opinion. Here is my situation. I have 7 planes all .40-.60 size and 4 of them have 72mhz rx and the other 3 have spektrum rx.

I looked everywhere on the web and can't find a definite answer.


Sounds about like the route I was on years ago.9C with a SPM module.I had some Rxs and Bind and Fly was taking off.The "other brands" didnt even have a 2.4 system on the market.I bought a used heli that came with a DX7(original) that was basically new 6 months from being released.Holy cow.I immediately noticed a huge in that "connected feeling".I had a little learning curve to modify my power supply schemes to keep enough voltage at the Rx bus so everything stayed happy.
I had already had some experience with failures on 72 from low battery packs.Never a loss of control long enough to cause a crash luckily but it made me look into it more and know how to test for it.So when I crossed over to 2.4 I understood that it was more power hungry in a way and even more critical to maintain voltage because a brownout didnt just cause everything to get glitchy or slow it would cause a Rx to reboot and the timeframe for a reboot was a long enough loss of control that a crash would be likely.We basically had AR6100s and AR7000s for basic Rxs.As we got digital servos that were even hungrier it was even more difficult to maintain an adequate power supply.The basic single AA pack with a tiny lead and switch just wasnt doing it anymore for the most part.We ran dual packs or a pack that could provide more current(amps) and larger gauge leads.Then we ran into the limitation of the servo type connector and sometimes had to use even if the pack and lead was adequate.
Unlike many that just plugged stuff in and expected it to work I (knock on wood) have never had an inflight brownout or loss of control.
I have stayed with SPM and enjoy alot of the BNF stuff also now.
Other systems have come along and unlike when we used 72 with its minor incompatibility problems with 2.4 we have pretty much zero compatibiity across different brands.About the only thing left that is would be servos and other accessory items like gyros and govs etc.

All the systems are good but I chose to stay with SPM.They have been at it longer than anyone else in the RC industry.The selection of equipment is more flexible IMO.Compatibility with BNF is another big plus IMO.The other thing to think about is how many others around if your in a club or just other modelers in general have the same system.If/when you need help with something how many others are around that are familiar with what you have.Everyones situation is different.There are choices to be made.Unless you are going to have multiple radios of different brands the decision you make pretty much locks you into having all the same equip most notably Rxs.
I had a chance to use an Aurora A9.Its a nice radio.Very little learning curve to the programming.
I tryed helping a guy with an 8FG at the field and I had to fumble through the programming.Im sure it would be fine once I learned it but it just didnt seem intuitive to me.
My Spektrum radios since I retired my DX7(original) are all brain dead easy to program.And so much easier to explain to others how to do things.
Just my 42 cents worth.

Whilst Hitec do not make a module to match the Spektrum requirements, there are aftermarket methods of providing a link between an Aurora 9 and Spektrum receivers:

. Spectra 2.4GHz module - Spektrum DIY Conversion Fly BNF's. with DM8 for MZ and DC/DC converter. Original article post #59

. Spectra 2.4GHz module - Spektrum DSM2-DSMX transmitter modules for Hitec Aurora 9/Optic 6/ Eclipse 7

Modules are always a good option for having access to BNF models.Generally if thats a large determining factor is choosing a system to commit to a module does have its distinct disadvantages to a native system.Ive flown most other systems with an SPM module and the "connected feeling" just isnt there compared side to side with my native SPM Txs.Thats neither here or there.IMO it is what it is.You also wont be using DSMX with a module.
I did finally get to fly and play with the programming on an A9 just last week.Its really a nice radio.Feels good.Flies good.IIRC I saw it has multiple temp and volt channels.I didnt get to play with the telemetry much as the guy who had it hasnt figured out its worth yet I guess.If I was starting off cold going into 2.4 it would be a hard choice between all of the brands.
The debate over which is better has kind of gone to the wayside for the most part IMO.They are all good.Price is pretty competitive between them all for the most part.
Support is there unless you decide to go the China/HK route and initially spend less.They seem to be trying to catch up on support.Ill leave it at that.

So to judsterky.
Sorry we kind of went off track but it was a loaded question.You can gain compatibility with SPM using a module but its not the same as a native system.If your going to commit to one system for the most part you will need to stay with like brand Rxs.You may decide to use something other than SPM primarily and have a module to use BNF and other SPM stuff but you lose DSMX availability.
Im hesitant to say there is noticeable latency but IMO for me I can immediately tell a lack of crisp connection feel.Its a Whatever you do will probably be a good choice.
Lots of factors to get what will be right for you.Thats the tough part.We are all different for different reasons.

The module makes absolutely no discernable difference in latency or whatever between a fixed or removable module type
of transmitter, except perhaps the "fixed" Tx is a little thinner and fractionally lighter.
The module can not have any possible bearing on the menu nor how the sticks feel.
To avoid a lengthy response late at night, suggest you read the Q&A of the most recent similar threads, the
decisions reached and why at end of the following:
(There have been no recent threads there where the OP ended up buying the other brand.)

. Hitec Aurora 9 vs. Spektrum DX8
. Help Me Decide Aurora 9 or DX-8
. Aurora 9 or DX8 ?

Compatibility with BNF is another big plus IMO -
a number of local stores sell more receiver ready versions or swap the rx out for another brand.

Status: offline 		I bought a Hitec module for my Futaba 8u and a bunch of receivers. When the 8U stared to go I just bought a Tx only Aurora 9 kit. The question for you how many of each receiver do you have? I would suggest buying the brand of Tx you have the most receivers for. Both Hitec and Spectrum receivers are much less expensive then Futaba or JR.

Status: offline 		As far as the Aurora 9, I have owned the same TX one for over 3 years. It has a timer on it that records how long it has operated. It currently shows over 330 hours of operation. I have had NO glitches with this TX or the Optima 6/7/9 channel receivers. I have 14 receivers on various electric, nitro , and gas models. No issues. I do not know what is compatible with Hitec technology. I really have not pursued that angle. There is NOT a clone (yet) for the Optima RXs. There is a clone RX sold by HK for the Minima receiver, a very small RX for gliders and park flyers. It requires the owner of the Aurora to upgrade their module with new software. It takes about two minutes to accomplsh this on your PC from the company's website. You need an HPP-22 module to talk between the PC and RC equipment.

Status: offline 		It seems like I keep changing my mine on radios. Now I'm leaning towards a DX7. I know someone that just paid $299.00 for one with the promotional 3 receivers included. That's about $150.00 of free receivers with it. Also fully compatible with spektrum clones for park flyers aka Hobby King orange rx. I really don't want to mess with the modules anymore. I spent the last 3 years switching out radio stuff just to fly certain planes of mine….arrrgh! Anyway I'm going to call some local hobby stores and see if they have any more DX7's left with the promo rx's

Also, One thing I still don't get is a lot of people still are saying "don't buy the Chinese crap aka clones, etc. Well again I never had a plane go in before using a clone so my experience's been fine. Also, is there really a difference between something made in Taiwan "where spektrums are made" compared to something made in China?? Just a small island off the coast of China……hmm. Just saying, after all….just about everything is made in China.

When flying RC, you always take Risks. Too Cold, Too Cloudy, Too Windy, Short Runway, etc.. If you buy an Off Brand Rx clone, you have to ask whether the Quality Control is as good as the Brand Name you are using. Is the Warranty, Service, and Support as good with the Clone as it is with the Brand Name? Just because everything is made in China does not mean they are all equal.

If I buy a cheap watch and it only lasts a year, I throw it away and buy another. If I buy a cheap Rx and it fails, destroying a $700 aircraft, it is not a risk I am willing to take. I have not used Clones, so I have no personal experience. If you trust them, then use them. It is a personal decision.

neither of which?

There is with a DIY or a commercial made in USA module.
As in post #10 All Hitec & Futaba Modular Transmitters (ex 14MZ type module)
operate Spektrum receivers without any reported problems - all users very happy. even with the small BNF.

Status: offline 		Couple of other little things. Modules and such don't have Spektrum Model match which means a lot for safety purposes. Also I'd take one more step up and get the DX8 which has the backlit screen and timer that starts with throttle input. And 30 model memory. I have 18 orange rcvrs in use with no problems, in planes up to 40 size. To many choices.
