Not compatible, you must check the orange hk dsm compatible module to enter in the realm of plastic fantastic $6 receivers.

What really bothers me is the long antennas on both the rx and the tx.

So I have heard the name FrSky quite a bit and decided to look at this thread. Is the FrSky 2.4ghz module for JR compatible with the $6 HK 2.4ghz rx's? Also is it compatible for BNF models?

I'm completely new to 2.4ghz so I don't know much about it and I may be asking stupid questions

Also, what's the average range when using one of these modules and one of those cheap HK rx's?

Thanks,
Nicholas
The Turnnigy 9x radio will accept the FrSKY DJT nodule http://www.alofthobbies.com/jr-trans...ry-module.html (in the USA)

Note -- there are two different companies at play here.
FLTsky makes the transmitter knows as the Turnigy 9x

FrSKY (pronounced Freesky) makes the modules and telemetry sensors.

So...
I'll go out on a limb and simply make a recommendation.

Buy a Hobby King http://www.hobbyking.com/hobbyking/s...arehouse_.html and pull the transmitter module.

Buy a Smartieparts card to put in that transmitter so you can connect the transmitter to the computer and change the POS (Piece of Stuff) firmeware that it comes with for some really exciting firmware like er9x or open9x. See http://9xforums.com for more information there.

Pitch the module the transmitter came with. Buy the http://www.alofthobbies.com/jr-trans...ry-module.html DJT and use the ACCST protocol for your models. It's comparable with FASST. For 8 channel receivers use http://www.alofthobbies.com/frsky-d8...telemetry.html For 4 channel receivers use http://www.alofthobbies.com/frsky-d4r-ii.html

When you are ready you can add telemetry sensors to these receivers.

The FrSKY system is not as cheap as the FLYSKY --- but it's infinately better.

The upgrading to the better software in the transmitter sounds frightening -- it's not and it's amazing how much transmitter you get. http://www.smartieparts.com/shop/ind...roducts_id=331 If you're electronnically inclined you could do the same as the smartieparts board -- but I'm not really inclined to solder on the circuit board -- and this solution is a set in place and screws to hold.

Last option you might consider is the hobby king backlight for the Turnigy 9x It's only about $5 -- but I don't know if it's in the U.S. warehouse... but next time you order from China.

I know that's alot of stuff in a short post -- but it represents a couple years of trial and error for me and hundreds and hundreds and hundreds of posts read.

I highly suggest using Aloft Hobbies based here in the U.S. because the prices are comparable to China alternatives, the shipping is very fast. and customer service is remarkable.

Thanks for the info, but I'd like to stick with my JR8103. The main reason is because I don't want to have to switch all of my 72mhz planes over to 2.4ghz. What I want is to have a 2.4 module when I'm flying 2.4ghz and when I want to fly 72mhz I'll just pop in my 72mhz module.

So if the FrSky JR module isn't compatible with the orange hk receivers, then what is?

Thanks,
Nicholas

HK will be re-releasing the Orange DSM2/X module soon. These will fit right in the 8103 module bay and will fly all the spektrum/compatible orange Rx's.

Just get one of these.

It won't be FrSky but DSM2/X which is what you want I think. That way you have your existing 72 or DSM2/X to work with the Orange receivers by changing the module.

The recommendation to convert to FrSky seems to be overkill for what you are seeking IMO. Folks are understandably enthusiastic about FrSky on this forum (I am!) but I don't think converting makes sense in your situation.

HK should be getting back above water with the Orange Spektrum DSM2 / DSMX compatible JR module. Should drop in to your 8103 and work.

I have some from the first shipment and have tested them in a JR 9303 & 10X systems. Bound to HK Orange 6 & 9 channel receivers and to Spektrum DSMX 4, 6 and 8 channel receivers.

No problems what so ever. Should get some flight time this weekend.

IMO no one should recommend others to buy the Orange DSMX module.

It is known to be bad right now (ch2 glitches), and is there any guarantee that they will be able to fix it?
They only use a few GUID, and there is therefore the chance that you could shoot another Orange user down if he happens to be on the same one.
(The theory is that they did not reverse engineer the DSMX hopping sequence algorithm, which is a function of GUID. Instead they simply observed it for some GUID and used only those ones. How many did they copy? Who knows)

Thanks, pat. That's useful info.

So the only sensible option for a JR user who wants to use a bunch of DSM2 receivers and not change their whole system to FrSky is a proper Spektrum DSM2 JR module which is now retailing at $109 and won't give you DSMX.

All of the BNF will work with DSM2.
If you are a 9X custom firmware user then the module from a DX4e will work fine and supports DSM2, DSMX and model match. But only 6 channels

I cut the small connector wire for telemetry sensor hub. RC module still upgradeable.

Wow. I guess I though it would be a lot cheaper than $100 to convert to 2.4ghz. Since I don't have that much to spend right now, I'll guess I'll wait…

Thanks everyone for all the help, URLs, and the advice. I really appreciate it.

Most people wanting just the spek module will sell the Rx for $75 and Net the module for $35-45 shipped... That's when they are in stock, of course.

You may also check the Radio FS forum. The module will come up for sale every once in a while for $65-$85 usually.
