Great review!

This statement alone reveals a troll in disguise.
So, for you, if I change the Aurora case plastic with a better one, the latency will decrease ?

Troll or ???? either one fits . . . .

Great "review"!

However, I am amazed by the 3 (almost 4 pages) of Model Match bashing.
Many not well argumented statements come by, I think the only one that has (limited) validity is jholen's , where he wants to use 4 memorypositions in the TX, and use ONE AND THE SAME RX for ALL the 4 airplanes.

From my limited understanding of model match, I wouldn't be able to do this very thing with a system that has model match, as my one receiver would be bound to a specific model. So if my situation I'd have to not only move the receiver out of each plane, but then take the time to re-bind it to each separate model. I'd think the most basic requirement for anyone flying a plane would be to check the transmitter to be sure you have the right model selected?...

(Well of course you can do it like this as you like, Model Match is clearly and indeed NOT designed to operate your equipment in this very way.)

True you have to rebind it when you physically move the RX from one plane to the next, but you're quite busy disconnecting, and then reconnecting all the servoleads, that takes effort as well...(okay rebinding will take some small extra effort, (but extra nonetheless).

During "normal" operation, you'd use 1 RX in 1 airplane. When installing THAT rx in that particular airplane you have to connect the servoleads ONCE. You also have to program the tx for that airplane ONCE. But before that you can do the programming, you have to bind the RX to the particular memory in the Tx ONCE.
After that, NO MORE binding is required. Not when you change the memory in the TX to fly another aircraft (which indeed has it's "own" receiver on board), not when your tx needs recharging after a days flying, not even when your motherinlaw is suddenly coming over for the weekend and the rest of the month...

This statement makes, if any sense at all, a statement of reversed cause and effect.

You see you ARE correct in the fact that it is COMMON SENSE to check the correct model selected in your transmitter and do a preflight check. (nothing wrong there ;-))

However as an ADDED (as in "extra at no cost" or "bonus" ) safety feature, for the one time that you do forget to check (and we've all been there in the past right, when we took off only to find the a/c rolling to a side, and correcting, hey the a/c rolls further, even bigger stick input, over 90 degrees angle of bank, worse sitation, full stick now, a/c impacts 3 seconds after takeoff, inverted and 80 degrees nose down, since the ailerons were reversed, IMPOSSIBLE because I always check , and yet it happened...) Sounds familiar?

Now same situation, with model match you want to throttle up, and hey WT F, the throttle does nothing, let's try the flightcontrols, whaaat, nothing either, hmmm, must be the battery right, nope voltage checks good, Awww wait found it, got the wrong model in my TX, plane is well, nobody hurt, you saved the day! (well actually Spektrum did for you...)This is how it's supposed to work....

Now by reversing the statement you say Spektrum makes you lazy and therefore the Modelmatch is silly.
The fact that you are getting lazy is YOUR VERY OWN complacency, not Spektrums! (I know, the truth hurts!)

(Your reasoning along the same line: I don't have to be careful in traffic, since my airbags and safetybelt will prevent me from injuries.
While in reality you still are careful in traffic, but in the event of a mishap occurring, you might just be saved from WORSE with the belt and bags...)

I rest my case...

My 2cts anyway, FWIW...

great 2 cts IMO MartinT

We're all entitled to our own opinions, and I would prefer to not have Model Match incorporated into my radio systems. Like I said, for me, it would be more trouble than it's worth. If you like it and need it, good for you, but don't expect me to have the same wants and needs as you.

I always do a preflight check that would eliminate the usefulness of Model Match. I also often use several transmitter memory allotments for each of my models for different flying styles and to test out new mixes and the like, so even if my radios had Model Match, I would still need to make sure I was selecting the right model in my transmitter.

I don't want to change course of this thread, so let me say,

Nice explanation of the Aurora Mike/pda4you!

I think: Apples/Oranges, Chevy/Ford, 6 of one/ 1/2 doz of the other ect. To the current discussion.

But---Can I interrupt to ask a question?
Now that I have decided to upgrade to a $puter tranmitter$---(cause my wife asked about my up coming "maybe birthday gift")

What advantages/options would a nine channel rx have over a seven channel rx? (for my future in the hobby)

Now the DX8 will be soon in the market, built in telemetry and only 11ms and 2048 resolution, what will be his excuse ??
Read some A9 threads here, I know some guys feeling a slower radio.. nothing else.

Please, take the advice of someone with 5 posts, 4 of which do nothing more than promote the DX8. The DX8 is not even out yet and I have yet to see a spec on the latency, but you seem to think frame rate and latency are the same thing. I got some latency for ya, how long does it take to get your plane back after losing signal with DSM2? THAT is one of the main reasons I am flying an A9 and didn't even consider a DX8.

So, I assume you were there when the R&D of the A9 went down and know all this as fact since you claim it. find something to do other than promote the spektrum DX8 in the Hitec threads.

I had 2 DX7's and they are both gone. I do have a 9503 which I use on up close small cheap models. I won't even put a Spektrum RX in a Radian because I DO NOT TRUST DSM2. I have complete confidences in my A9 and I feel ZERO difference between it and the 9503. Both have great features and you can pick the one you want, but I have no clue why you feel the need to come here and in other Hitec threads and spew spektrum propaganda.

Guys! For the last time! 11ms refers to the PWM frame rate of the DX8, not the latency! The frame rate only determines the speed of RX-to-servo communication whereas latency refers to the entire beginning to end TX-to-servo communication.

And hides his personal threats in PMs. I feel a ban coming just after 5 posts..

Good job on the review!

I love model match, some say it makes us lazy? How about everyone has a Blonde moment from time to time! I have went and pluged up my Heli a couple times and it did NOTHING. that god, I look down hey dummie the model is on your plane not the B400 . it saved me. with another radio would it just sat there and did nothing? FM 72 it most likley went nuts on me.


I wish all radio companys would let you selete to have model match or not to have it.

As far as fast or slow unless your a top pilot your never going to notice the driffrence i am sure. I fly the heck out of a foamy but never said well this one wont go as wild cause of the radio..Servos sure, radio I do not think its a issue.

He will just make a new account and do the same thing.

This was a well written and informative review. Thanks.

Spektrum owns all rights to Model Match. In order for another manufacture to use the name "Model Match" and the technology requires that company to pay Spektrum for its use. So I can understand Hitec/Futaba or whoever else not wanting to increase the price of their product in order to offer "Model Match".

I have owned 3 Spektrum transmitters and must say I was and still am a fan of Model Match, but the way the Aurora 9 prompts you on power up has kept me from trying to fly a model other than what is selected on my TX.

Since the A9 has telemetry, I think the option to enable Model Load would be nice. However, it should be an option in the setup menu so those that don't want it can avoid it all together.

Model Load

I think this is actually a better option than Model Match and it is free to use with no patents as far as I am aware.

Understood, But still... Why couldnt they all kinda work together. do we really need 100 driffrent radios, it was eisier in 1990's only a few choses either a $150 radio or a $300 or $600 one.

I guess if it asks you every time they help also, from the videos I have seen it only asks if you want it to transmit or not
