Usmile CC2500 NRF24L01 A7105 CYRF6936 4 in 1 RF Multiprotocol TX module for Frsky Turnigy 9xr pro Control all toy-grade quad X5C X8C Hubsan H107C H107D JJRC 1000 with one transmitter(Frsky)

I THOUGHT IT WOULD A LEAST COME WITH SOME SORT OF MANUAL ON HOW TO INSTALL, AND HOW TO DIAL IN TO PROTOCOLS WITH MY TARRANIS Q X7, SO IM STUCK WITH THIS 4 IN 1 MODULE THAT I HAVE NO IDEA HOW TO INSTALL OR UTILIZE

performs flawlessly. modification of hardware isn't exactly a walk in the park, and definitely not recommended if you have little to no soldering experience. I took my time and it was worth it because now I have a chipped devo 7e running deviation. next I'm going to short the diode under the radiation shield to increase TX power output. I've modified the hardware.ini file to enable all radio modules and so far I've loaded a blade nano qx model onto the devo 7e (drag and drop into 'models' folder on devo in usb mode - start usb mode stock firmware, hold EXT and power on radio with usb cable plugged in - start usb mode with deviation firmware, hold ENT while powering on radio with usb cable plugged in) the models must be named model(#).ini otherwise the radio will not show the loaded model(s). the nano qx model I've loaded works well (DSMX) except the switching between stability / agility modes, it gets glitchy sometimes, I'm working on that right now. this is a must-have for the devo 7e, other models too, the mods opened doors that I never even knew about, there are so many things that can be done with this radio, but not without this 3 in 1 MCU chip, and not without the deviation firmware... and definitely not without soldering skills and basic electrical knowledge. I don't recommend doing this yourself if you're not comfortable with the tasks at hand. the hardest pin to solder was on the ARM chip, it's a very, very small set of pins grouped very closely together... it's a microchip... and mistakes can easily be made. I used a thinner gauge wire than the rest of the project just for this one pin, and I covered the pins next to it with a clamp on a razor blade when soldering it, holding it right in between the pins to prevent any solder from making a short between the pins on the chip. i knew that it was going to be the hardest part, so I did it first, everything else, even though still somewhat difficult to solder, was a piece of cake by comparison to soldering the chip. I didn't solder the new wires I added to the devo onto the new 3 in 1 MCU, instead I bent the pins on the new chip at an angle and I de-pinned a few RC radio channel connectors, covered each pin with heatshrink and simply plugged them into the appropriate locations. this way, I could easily unplug and return the chip if anything happened, I could change out the chip easily, I didn't have to solder anything else and these pins on the MCU are very close together, so it saved me a little bit. it also works perfectly, so I don't see a need to use solder on the MCU unless you'd rather do it that way. great item for certain devention / devo controllers, installation of this 3 in 1 MCU (and deviation firmware) enables so many features on the devention transmitters that otherwise wouldn't exist. do some research, too many models and protocols available to list!

They should really give some! info with it. Like a piece of paper that says what the protocols are. I am not very impressed but it works.

Awesome product. Love the ability to compile more protocols into the firmware!

Would be nice if it came with any type of instructions or manual or anything

So much cheaper than buying a very expensive radio for each protocol that you use. I paired this with a Turnigy 9XR Pro with no problem.

I like the size.
