Reason to get a X9303 for electric heli use?

[mjr_larkin]

I'm getting a 500 and 200 heli and will be buying a new tx with them. The dx7 sounds awsome. Is there any reason to go with the X9303 if i'm not going to be doing nitro? All i've heard is that the 9303 has a better feel to it (more solid construction). Other than that the dx7 wins in latency and has servo sync feature. The X9303 has 7 point curves instead of 5 and of course another 2 channels, but I don't there is a use for those. I see the pros use a x9303 but probably because they fly nitros.

Suggestions very appreciated thanks

Electrics can use simpler curves than Nitro. And, all modern helis with HH gyros don't really need many TX features... revo mix is a no-no, Gyro mode pages are overkill (just map it to the gear channel; it's actually easier than the Gyro page).

In short, the DX7 has PLENTY of features for flying helis. Even Nitro helis.

By the way, your post implied that the DX7 has lower latency than the X9303... not true, they are both "native" 2.4 radios. There may be a slight difference, but not enough to make any real difference. And, they both have model match, servo sync, etc. So no help with the decision there...

The X9303 is "nicer". Better gimbals, better screen, the click wheel is MUCH better than pressing buttons. All of this makes the radio easier to use. It also has higher resolution when used with the 9ch RX... but again, the "regular" resolution is just dandy. Back to the click wheel and screen: They do make the radio much easier to use. This cannot be overstated.


My opinion: If you think you are going to be in this hobby for a few years, with multiple birds, get the x9303, without question. It is an investment that will pay off along the lines of the old saying "good tools are a joy to use". If you are financially constrained at the moment, or still testing the waters of the hobby, get the DX7. It is plenty of radio; can't go wrong either way. Just depends on how important "better" is to you.

Hy,

i have now a X9303 on my electric Heli-Pro Revolution with a AR 9000 Reciever....

Bevor the JR Radio, i used a Futaba FF9...! (sucks...)

The X9303 works really better and faster and the 120° program works exactly...!

Nice Radio!!! no problems in the air!!

i think that i never change this system back to....

I was in the same position of chooseing a month or so ago. I went with the 9303 as I felt it offered more flexibility down the road.

Both are good radios IMO. The 9303 is better, just depends on weather you want to spend the extra $.

If you need to "justify" it. The X9303 has a slow start out of throttle hold so you can bail out of autos with the electric. :thumbup:

The X9303 has 7 point curves instead of 5

For an electric heli, you only really need a 3-point curve.
for an IC heli, the 7 point curves can be easily justified.

Same with pitch curves (for any heli)
A properly set-up helicopter onle needs a 3 point curve.


One thing I like about my x9303, is that it is really the easiest radio to set up.
I can set up a heli literally in about 5 minutes, whereas it would take me 20-30 minutes with the DX7.

A properly set-up helicopter onle needs a 3 point curve.

Really? what if I want to run the "standard electric" 0-40-60-80-100 throttle curve for normal mode? Scale helicopters want to look natural when they fly not be in 3D mode. I mean I could argue you do not really "need" a curve with an electric 3D heli because of soft start in the ESC.

[Ginvent]

I see a five point curve minimum, some people like S curves on picth. Any computer radio that comes out now should have 5 point curves at least, anyhting less is old school.

Also the radio shoud really outlast the heli IMO, you could be flying the x9303 5 years from now and who knows what kinda stuff you be useing then, better get the BEST radio you can afford, trust me I learn that the hard way, *hugs his DX7*

especially for pitch, when should you ever have an other-than-linear pitch curve?

especially for pitch, when should you ever have an other-than-linear pitch curve?Like Ginvent said in the post above, some people like S-curves on pitch. Certainly can't do that working with only 3 points.

Scale, AP, F3C all are applications that a non linear picth curve can make life easier, Also in sport/3D flying a S curve can make collective VERY sensitive or progressive.

My point was really, in response to the topic starter, who was looking at a 7 point curve vs a 5 point curve.
5 points is perfect, 3 is all you NEED, 7 is totally overkill for electric or nitro, unless you're running a gasser or a turbine, then I can totally see running a 7 point.

The dx7 sounds awsome. Is there any reason to go with the X9303
No. Save yourself the extra couple hundred bucks you save by getting the DX7, buy yourself some extra batteries and/or an additional charger/ balaancer.

If You , your own personal self, are not compelled to get the top of the line radio,well.............frankly just dont, I say get the best radio you can afford but the DX7 and x9303 are both great radio, If you feel money is better spent on lipos they go fro those.

Dood I could make great use of the 7 point curve, It puts more S in the curve, but I couldnt afford the 9303 (PPM or SS).


Though before you by be sure to TRY and look over each radio thourouly try to Hold both or at least see all the screen menus.

If the 9303 was out when I bought my radio (DX7), I probably would have chosen that one... but that's just me.
Not sure I could continue that line of thinking if the 12X was available. ;)
It would be nice to have but at $1500 :shock: I may have to wait until I wear out my DX7. And who knows, by then the F-22-XYZ may be out. :smokin:
