Status: offline 		Ok This has been asked numerous times and I can now give a definitive answer...

YES!

Ok, more explanation....

The Walkera Transmitter -DOES- indeed work with OTHER Receivers.... and it works VERY well too.

It uses the same shift pattern as the Airtronic/JR hardware.

All you need to do to improve/replace/upgrade your RX is to get a crystal with the same frequency and use a Airtronic/JR compatible shift pattern.

I was able to determine this with a Hitec Supreme II HRD-08RD 3800 shift selectable receiver.

One warning note.

The channel assignment pattern is different than it would be on a normal radio!

So Channel 1 is -NOT- the aileron and 2 is NOT the pitch... (I believe 2 is Aileron and 3 is pitch, etc.)

You will have to play around with the plugs, but it DOES work...

I would advise you get a 7 channel RX just in case.

Status: offline 		I'm thinking of getting this Tx: HITEC Eclipse Transmitter w/Spectra Module. I can get a good deal on a used one, but the new ones are QPCM (Quick PCM). Do you know the difference in QPCM and regular PCM and which is more compatible more stuff. I want to use this on my DF36 and Blade CP. It does pos. neg. shifts. I'm not sure it would work with the DF 36 Rx, but the used one I can get comes with a Rx, too.
Any thoughts?

http://www.deeteeenterprises.com/NS.HiTec.Eclipse.7.QPCM.php

Effectively saying that you'll need either a Hitec QPCM receiver or a Hitec FM receiver for this radio.

It's a nice radio though.

The upside is that it should work with the HFD-08RD 3800 which has FM stamped on the label.

I really like the 3800 as it seems to be able to work with most PCM systems including the Walkera.

What I get out of it is that the new model lets you chose between QPCM and PCM, but only Hitec Rx's can have QPCM and not all of them do. Here's what the FAQ says about Rx's:

quote:

Any modern FM receiver will work; all you need to do is make sure you have selected the proper shift in the menu. Hitec and Futaba are negative shift and Airtronics, JR and Multiplex are positive shift.


I don't think any of my stuff is PCM anyway. I've got 5 helis (if you count my Bladerunner). I'd just like to be able to use 1 Tx with all of them.

So, what do you think?

Status: offline 		Slotcar, Walkera uses their own bizzare modulation on their radios. It's (unlikely) that the Walkera RX will work with any other radio. I have an eclipse 7, and i've never been able to get any Walkera receiver to work with it. (4in1's, etc.).

I have, however, managed to get Walkera TX's to work with other recievers.

The eclipse 7 works with just about any (standard) FM receiver out there. I love this radio. I've never had any interference problems using it in FM with all sorts of recievers. Both single and dual conversion. I would not trust my heli to a Walkera RX though, just spend the $20 or $30 or whatever it is for a good Hitec RX and be done with it. Even GWS RX's are a ton better than the Walkera stuff.

If you can score an eclipse 7 for cheap, then jump all over it, because it's a fantastic radio .
I got mine off ebay from a fellow. Almost new in box, $160. The radio sells brand new with the spectra module for $200, so that was pretty good .

Oh, I should mention, the Eclipse 7 is alot bigger than the Walkera TX. Looks like it was designed for bigger hands. It may take a bit getting used too after using the small Walkera TX for so long .

Yup that's exactly what I got out of it.

Wait a sec!

Didn't you see the top of this thread?

I started it by stating that the Walkera stuff is INDEED compatible with the JR/Aitronics shift RX's and TX's.

I have it working just fine both the RD602 RX with a JR radio, and the Walkera TX with a Hitec (in JR/Airtronics mode) RX.

As I stated in the post, the only thing unusual is the channel assignments. Walkera's channel mapping is a bit strange.

Status: offline 		Thanks credence. It would be nice to have one radio for everything. I like the feel of the Walkera Tx better than the E-flite or Esky Tx's I have, but any Tx I could get used to would be better than the constant switching. The E-flite and Esky are smoother, but the way they're balanced, you have to hold them near the bottom. The problem is the grip contours on the back are small and near the top, and the sticks are high so they're hard to reach when holding the Tx near the bottom. It's not a good design.
I've got an Esky 4in1 coming for my DF4. I want the adjustments for the gyro and mixing, and the DF4 4in1 doesn't have them. If you run a lot of blade pitch, even setting the rudder trim full right won't stop it for slowly spinning left.
The used Tx I'm looking at comes with an 8 CH Rx that I could use with the DF 36. If I get a new one instead and can't get it working with the DF36 Rx, I'll just get another Rx. Opjose seems to think they can be made to work together, but like everyone else I was under the impression they won't. Someone else posted that the DF36 Tx won't even work with the DF4 Rx. I also thought the crystals that Walkera uses were different than everything else.
Anyway, it'll be nice to have just one Tx to run everything.

Status: offline 		Opjose/credence,

Recently fried my Walkera rx (35Mhz) and would love to take the opportunity to get rid of the walkera rx and trazmitter ... however I have just started this hobbie so I would like to initially replace the walkera rx only.

I have found the following JR receiver on ebay

http://cgi.ebay.co.uk/New-6Ch-JR-Type-FM-Receiver-35-36-72Mhz-Avaliable_W0QQitemZ6034243233QQcategoryZ34056QQrdZ1QQcmdZViewItem

From your post the JR rx seems to be compatable, am I right in thinking that if I order the 35Mhz JR receiver that's all I would need (apart from playing around with the plugs) or do I also need to do/buy something else.

Your help is appreciated !

Hitec Eclipse 7 with spectra module is a great radio, I use one for couple years and served me well for the fixed wing planes.

The minor draw back is: 1, the supplied Nicd pack is 600maH, only last for about 80min, it is easy to upgrade with a higher capacity pack. 2, only 7 model memory and there's no upgrade available. 3, For ccpm, only support 120 & 180 swash but you can manually program the mix for the 90 swash.

eh, still missed it... THEY do work with other radios!

That may work fine.

Just make sure that you get a crystal that exactly matches the Walkera's.

BTW: you have the 35mhz version?

Bear in mind that I have not tried that particular RX, as I stated I have had no problems with JR radios and the Hitec Supreme II RX.
