I was just about set on the Hitec Aurora 9 when I saw the 9503 news. Getting back into RC and intend to fly SCALE park type electrics and larger .60 size gas/electric scale ARF's.
What radio do you recommend for my SCALE needs???
A) What is the throttle timer feature on the JR and does the Aurora have?
B) Does the JR have a servo slow down feature? I like that on the Aurora for scale retracts, flaps, etc.!!
C) Does Hitec have MICRO receivers for park type electrics??

A)Don't Know
B)Yes. Retract servos are funny animals, though. They go stop to stop(180 degrees) regardless of travel adjust commands from the transmitter. Whether they can be slowed, I don't know. If pneumatic gear, then that is valve controlled and not dependent on the transmitter.
C)You can use servos from any manufacturer with any transmitter/receiver(99.9% of the time)

The new X9503 has the option of assigning a timer function to the throttle stick. This has been standard on many other competing radios for a long time. For wet power fliers it is the only reliable way to control the timer, any timer set to a switch results in an un timed flight for me, at least
The X9303 has servo speed control, so I would think the new X9503 would too.
Retract servos are not proportional servos, so you cannot control their speed[&o]I'm sure it will take some time for Hitec to get a complete lineup of receivers in the pipeline.

A) Aurora has dual customizable timers and both can be throttle activated.
C) The Optima 6 and 7 are perfectly suitable for Park Flyers (15g/17g.) We're even flying them in indoor competition foamies with the case removed which gets them down to about 8g. Smaller 4g RX's are in the works.

You can review the Aurora manual here: http://www.hitecrcd.com/product_file...a_9_manual.pdf

Some interesting testing on the Aurora w/ Optima 7ch RX with the single BODA antenna which shows phenomenal range checks with the antenna INSIDE a carbon fiber fuse here: http://www.rcgroups.com/forums/showp...6&postcount=45

One major shortcoming of the 9303 was the lack of the ability to include trims in programmable mixes. This prevented use of two channels to drive two servos attached to the same surface like an aileron or rudder with 2 servos because it was not possible to trim the two servos together.

Has anyone been close enough to the 9503 to know if this hole has been filled?

That is only partially true for the ACRO configuration and is not true for either GLID or HELI configurations. There is a major inconvenience when setting up two ailerons each using two servos on the 9303. Or in the case of a bipe, having a common trim for all four ailerons. It can be worked around if you’re willing to use the AUX TRIM switch instead of the aileron trim. The rudder, motor and elevator on the 9303 can all use dual servos with no problems.

The 11X has a 4-aileron wing type that should be similar on the 12X. If the 9503 is using the 11X programming, then this work around will be unnecessary. From the little information about the 11X, if you are going to use multiple servos on surfaces, the 12X is superior to the 9303 or the Aurora 9. The 12X has a balance menu where you can match the servos at seven different points. The 9303 can only match the endpoints and the center. As far as I can determine from the instructions, this is also true for the Aurora.

I am very suprised to hear this, as my lowley DX7 has two types of PMixes. PMix 1 through 4 do NOT pass the trim to the slave channel, and PMix 5 & 6 DO pass it to the slave channel. I was thinking of upgrading to a 9x03, so knowing this for certain is important to me also.

With the Aurora one could use multi-point mixes but it is totally unnecessary. Just name two channels the same name and they are automatically mixed, then set center and end points on one channel to match the other.

There's no need for a multi-point mix or balance function as long as the linkages on the two servos are reasonably close to the same. Before programming multiple points to match two servos you should be adjusting the linkage to get the two parts as close as possible mechanically.

The 9303 in ACRO has two ways of mating channels and having a common trim. The simplest is to designate the wing/tail type (flaperon, delta, v-tail). Or it can be done in a manner similar to the description you gave for the Aurora. Use the dual/mate function to tie another channel with the aileron, elevator, rudder, flap or engine (for twin engines). The problem arises when there is a need for more than one channel to be mated to the primary. The 12X and 11X (as shown on the JR Japan web site) solve this problem for the four-servo ailerons by adding the 4-AILE wing type. On the 9303 the throttle trim is carried through on all the program mixes.

Whether the 9503 uses the 11X programming or the one presently used in the 9303 is something we all have to wait and see. I don’t know why JR didn’t in the ACRO configuration make it the same as the GLID and HELI, where any master channel with a "+" suffix has its trim carried through to the slave channel. The dual/mate function is easier to set up than a program mix but it does limits the number of channels that can be tied together.

As I don’t fly any aircraft that uses ganged servos, I can’t say how much better the 12X balance menu is compared to just matching the endpoints and center. But it comes up automatically when channels are mated. So one can make use of it or ignore it.

If you check Horizon's own advertising, they say "Proven JR 9303 transmitter programming", so I think that question is already answered. Only difference from the X9303 is the throttle stick timer, backlight and more model memories. Just a way to keep a place in the market while they are working on creating a match for the Aurora, IMHO.

Anyone have an idea of the pushbutton looking control on the top-left of the 9503? Is it a throttle kill similar to the DX6i?

If it's like the X9303 air version, it's the trainer switch. The heli version uses a more common spring loaded toggle for the trainer switch.

B). Yes you can slow down the servos. For flaps, you can specify travel for two flap positions and how long it should take(up to 2 seconds) for the flap to get to those positions. Elevator correction can also be mixed in with the flaps.

fizzwater2

My Feedback: (61)

Just wondering - when you have the elevator correction mixed in with the flaps, does the elevator also take the two seconds or whatever to get fully altered to the "with flaps" condition, or does it go right away when you hit the flap switch?

AWorrest

My Feedback: (5)

It will depend on how you couple your elevator to the flaps. On the 9303 you can slow down a channel as much as 15 seconds for 60 degree rotation. But this slow down is not carried through to the slave channel on a program mix. So while the flap movement is slowed down, the elevator is not.

There is another way to couple the flaps and elevator by using the FLAP SYS menu. There the delay is 2 seconds max. Using this menu, the flaps and elevator are moving in sync.

i contacted horizon about the 9503 and she said no differance in program. you can transfer 9303 to 9503 perfectly.. i already have one on order....

ricardinho

just got my 9503 and one more surprise is it has 2048 resulution. i think they wanted surprise us. nice radio. looks more refined th the 9303. nice back light also.. the best for any aplication for the money....

adaptabl

Second best to the A9.

You must be one of the first to get your hands on the 9503. Would love to get some more feedback from you for myself and everyone else looking at it. Apart from the throttle stick timer, back light and model memories has anything else changed ? Has the multiple wing servos mixing been resolved ?

ricardinho

they have changed more things . it is now 2048 resulution. same as the 12x. its cleaner looking. great radio. not the sure of the multiple servo thing. i never had a problem with that with my 9303.. explain a little better what you meen.... i used mine today. seems to have much better response then my 9303..

ricardinho

i dont know you would have to prove that one to me....

He may mean mixing Aileron servos in a Biplane that has a servo on each of 4 Ailerons.

ricardinho

never had to do that. i am sure this problem is resolved.

2048 Resolution...does that mean the 921RX it is shipping with is now 2048 too or was it always ? I should be getting mine in the next day or so wish someone would do a review...if I did not have so much Spektrum JR stuff I would probably be looking at the A9 - HT really did a great job of it.
