N Spektrum 9 channel RX designed just for Giant Scale

[KenDobson]

Little help guys, I have a 50cc compy-arf with a Da50. If I used this reciever with a123's and hitec 5955tg servous would this be a good light set-up? what else would I need? Will this rec'er work with a dx7 or do you have to wait for a dx9?

Thanks

You'd be fine with that, in fact, you'd be fine with an AR7000 or AR9000, you don't need all the power handling of the 9100. The AR9000 works with the DX7, so the AR9100 should work also. There is no DX9, and there isn't going to be one, JR released the X9303, since Spektrum isn't going above 7 channels.

I don't think that's what he was getting at. I agree that running unregulated lithiums in a transmitter that wasn't designed for them is crazy, and you're asking for problems. What he was getting at is that most consumer electronics, such as MP3 players, cell phones, laptops, etc. are using Li-ions now with almost no issues (they do blow up every now and again, but that's very rare). The benefits for doing this are quick charging, no self-discharging, and high capacity density. I would love to have a lighter transmitter. A transmitter is really the perfect piece of electronics for native li-ion support: steady, slow current draw. The issue isn't that there isn't enough run time with Nimh's, it's that there are other advantages to lithiums.

Also, I do think this receiver is awesome. Extra power buses and switches always seemed to me like a set-up that was heavier, more complicated, and more expensive than it needs to be. I really hoped that manufacturers would provide a better solution.

so the ar9100 will work with the 9303 2.4?

I totally agree, also the 'simpler' set up may help to reduce the intimidation factor, keep the cost down and encourage more people to fly the larger aeroplanes and experience how fantastic they are to own and operate.

Once the 12 channel receiver comes out you be able to run separate channels for each servo like people already do with the 14 MZ. I already mix 4 channels with my 10X and AR9000 to run 4 aileron servos with no matchboxes. The servo matching is done in the transmitter.

Very interesting solution to the multiple servos per surface problems, any issues or is it relativly straight forward to set up?

Yes, definitely.

And to Emanuel, A123 is the ideal power source to use with the AR9100. One pack into one receiver will supply all the current you will ever need. If you want a fully redundant system use 2 packs into 2 receivers. No regulators, no switches in the way, just raw power and lots of it. It would make Tim (the tool man) Taylor get a woodie!

I do have a question for Horizon tech support.

There are 2 power inputs to the AR9100. I am curious if these two inputs are common internally, such that with one battery connected the other lines are hot.
If so, one could easily make a jumper to connect the free power leads on each of two receivers.

This would allow either use of one battery pack on 2 receivers (I'm kind of drunk with power on the A123s, I feel like one pack can power anything) or with 2 battery packs it would give full redundancy of power supplies. If either pack did go dead the other would keep both receivers alive. This would also give you 18 places to plug stuff in.

I don't understand why the thing comes with "3" recievers. Didn't some of the earlier versions come with two? And what are you guys talking about not using any switches? You still have to run switches correct?

[Zeeb]

I haven't figured out why it's got three satellite rx's either and the webpage says it can use four, but that didn't stop me from back ordering one for my new Compy that'll have A123's for power...

The other rx's from the AR6200 on up to the AR9000 and R921's only come with one satellite rx so you have to buy the additional ones. At $30 a pop for satellite rx's, the price on the new AR9100 with three of them is pretty reasonable.

I've been running my R921's with two satellite rx's and the data logger information is really useful in telling you if you need to relocate one of the rx's. So far I've only had to make one slight change to get great readings on what each rx is seeing, but who knows? If you've got a bigger model a third satellite rx might be good for some folks piece of mind?

I've not seen anything posted about needing more satellite rx's, but if you've got them in hand, and you've got the room....

I may have to experiment with it when I get stuff put together.

Anybody else seeing anything posted about needing more than two satellite rx's?

The AR9000 has two built in the main box and one satellite. The AR9100 has an internal electronic switch... so you don't need one between the bat's and the reciever.

[Zeeb]

It's true that the 9100 doesn't have a switch between the batteries and the rx, but it's a bit misleading to just note that as the "soft switch" must be installed to operate the rx's internal switch. It's also a fail on system so there is a small voltage going across that all the time and the batteries must be disconnected if the model is not going to be flown for some time.

The manual says the batteries are "isolated" but I don't think addresses Tom's question specifically. If it's just a diode on the input side of the power supply wires, then no. It also doesn't address whether or not there is the common ground thing on the rx buss between the two inputs. It'd be great if the grounds are isolated as well since that will simplify charging the batteries.
