I sold one of my Scisky DSM2 builds as a BNF to get a friend into the hobby. I told him to get a Devo 7e or Spektrum DX6i or 5e on eBay and I would get him set up. He was all proud when I went by his place and he had a DXE waiting all ready to go. He didn’t get what I told him, and I hadn’t previously played with a DXE before, but how bad could it be right?
I quickly tried to bind it to the quad but promptly failed. I tried again several times because in my past experience Spektrums can be a little finicky but eventually bind. No go! So I told him to let me take it home and do some research and I’ll figure it out and get it back to him soon. Little did I know…
I’m a Taranis guy with a 9XD+ and my DIY Spektrum JR hack module built from a harvested DX6i RF module (for those rare times I need a DSM2/X TX). So take what comes next with a grain of salt.
What a disaster of a TX this DXE thing is!!! I’m not a huge fan of Horizon or Spektrum as it is, but this whole concept is bad, and the way it’s been implemented is horrible.
How can they sell a DSMX TX that isn’t backward compatible with DSM2?
Worse yet, how can they sell a programmable TX that can’t be programmed without connecting it to a PC or mobile device but then not include the required proprietary programming cable with the TX?
Worse than even that, how can they embed a chip into the cable to make it proprietary and prevent users from making their own if they wish?
How can they then penalize their users even further by charging a ransom for the privilege of purchasing the unnecessarily proprietary cable? It’s a USB cable for crying out loud!!!
I see this as hostile and abusive behavior by Spektrum/Horizon towards their customers. This wasn’t the original reason I chose Frsky over Spektrum way back when, but it certainly is the reason from this day forward I will forever be sure to steer everyone I know away from anything to do with Spektrun/Horizon. Even all of my Tiny Whoops now have ZERO Spektrum/Horizon components in them.
All that ranting said, I was able to get the DXE to bind with a Lemon Satellite, without needing a full RX to do so. However it must be a DSMX version as this TX will not bind to a DSM2 RX no matter how hard you try. I used the Betaflight CLI command “set spektrum_sat_bind=8” to get it to work (and it still took 2 or 3 tries). But now the Throttle, Yaw, Pitch, & Roll endpoints are only around 1250-1850 and there is no way to set them wider to 1000-2000 without a PC/mobile device and the infamous proprietary programming cable.
So I reluctantly ordered the wildly overpriced USB cable, which hasn’t arrived yet. I’ll see what can be done to make this into a somewhat useful TX when the cable arrives. I sold the BNF at a loss because it was to a friend and I was playing the older brother getting him into the hobby. But in the mean time I can reflect on how I had to spend $35 more for the Lemon DSMX Sat and the proprietary programming cable (not to mention all the time & effort & pain & suffering) just to try to get it to work with this goofy TX.
I’m not happy, and not a Spektrum/Horizon fan at all.
