Hey all thinking I'm going to go to spectrum and wanted advance what you think my radio is worth and would anyone here be interested in purchasing Bluetooth mod installed holes for speakers opened up DR8-XP , V8FR-2 recs Frsky djt module and 9XR LIPO BATTERY

Just curious as to why you are thinking of changing?

Mike.

In my opinion , I would think you would go with erSky9x on Taranis-Plus radio as its a better radio,
then before dropping down to a Spectrum radio.

Picked up a blade 350qx and another scratch built that's has a spektrum 8channel rec in it already. I'd love to keep my pro but I'm having a hell of a time finding the spectrum module

There is this: http://spektrumrc.com/Products/Default. ... SPMMSJR720.

There is this project that would allow you to use DSM protocol: http://www.rcgroups.com/forums/showthread.php?t=2165676.
Bangood are selling a ready made version, see this thread: http://www.rcgroups.com/forums/showthread.php?t=2709034.
It just needs mounting in a module case, mine is in a DJT case.

Mike.

Hmm Mike would I need to change anything in your firmware to use it or is it pretty much plug and play also case isn't a big deal I can 3D print one

There is this case option too: http://www.banggood.com/Multi-Protocol- ... 85320.html

Multi Protocol TX Transmitter Module: http://www.banggood.com/2_4G-CC2500-A71 ... ign=375733

It's plug and play. You may use it as bought, turning the rotary switch to select the protocol, and using PPM as the protocol. By just bridging two pairs of solder pads, you also enable it to use a serial protocol "MULTI" that is supported by the test versions of ersky9x I've posted.
It would benefit from updating the firmware on it. For that you need to solder on a 6-way header, and have a 3.3V capable USBASP programmer (or similar) and have the Arduino development tools on your PC.

Mike.

What would " multi " allow is it worth the firmware update ?

Well pretty sure you all have convinced me to keep my 9 lol

The MULTI module includes 4 RF chips, and so handles a great many of the protocols in use. It does all the FrSky protocols (pre-LBT), the DSM protocols, the original FlySky/Turnigy protocol, and many more.

I use mine to fly my cheerson CX10 micro quad and my Eachine H8-3D.

anyone have a link to programer i would need for the board?

http://nicecircuits.com/wp-content/uplo ... bottom.jpg this is the one i have

Unfortunately, the ready made board from Banggood doesn't include the serial bootloader. You need a USBASP or similar programmer, capable of operating at 3.3V to update the firmware.
I have got a serial bootloader on mine that would work with the device you show, but you still need a USBASP to get the bootloader on to the board.

Mike.

So this will do everything I need ?

It looks like it will do, although I'm not sure how to set it to 3.3V, and I can't see anything on the listing that tells you that, even though it says it does 3.3V.
As I mentioned earlier, you will need to add a 6-pin header to the MULTI module for the programmer to use.

Mike.

Ok thanks I just ordered this one seems a little more user friendly and more info on board

https://www.ebay.com/itm/261061966808

first off thanks a ton all this forum is fantastic !!! Mike can you confirm version number of your latest looks like im running ersky9x-r218 REVB-X is the test version you mentioned ? I don't see any labeled test.

Test versions are here.

Make sure you select the right binary file for your radio

GREAT THANKS AGAIN !! flashed second to newest one because i dont have the board yet now the waiting game as banggood is backordered grrrr

Ok guys kinda at a lose seems to be different guides to get this up and running Soldered RX/TX tabs and 6 pin usbasp 3.3v jumper selected updated to latest driver for usbasp now I'm stumped lol

This should be the documentation you need: https://github.com/pascallanger/DIY-Mul ... mpiling.md.
