The Futaba transmitters do not support bidirectional CRSF. You can not receive telemetry data. ELRS for LR without telemetry data is pretty useless for me. I had to buy a TX16S that supports bidirectional CRSF, even though I already had two Futaba transmitters.

Yes, this was always the case running CRSF on Futaba.

I did get the guy to turn his comments back on lol. It seems to be plug and play pretty much other than needing an OpenTX radio to update the firmware and change power settings on the micro module.

Hi man, read your post, super super helpful!! after a little over a year of doing the crossfire "mod" meaning powering it through the trainer port on the 16SZ I got a few questions for you and I'd be happy if you could answer them (:
first off the does trainer port allow you to go to max 500mw with no issues on the module? and has it been reliable enough powering it from the trainer port? what happens when you try to go above 500mw? and have you found any issues using this method meaning is it "reliable" as plugging it in the JR bay on the openTX radios?

Yes, I've been running 500mw fine with no issues to module or flight performance. I tend to run 200mw though since the battery does drain a little faster on 500mw. I think that's actually a TBS Crossfire module failsafe that it won't power past 500mw if there is no external lipo plugged into the XT30 port. It will default back to 500mw if its set higher and powered on without an external lipo. Personally, I feel no noticeable difference in control link performance between my Futaba using Crossfire and my Tango 2.

Thanks Again!! although interesting why Johnny and some other big names basically never use this method, this is even the recommended method by Futaba themselves... I mean having the ability to got up to 500mw without an external battery is the gold standard for the crossfire, its exactly like in the taranis unless your using a big battery inside instead of the stock one and I don't understand why would someone always carry and fly with external battery even though they're not using above 500mw cause there's no way they fly with more than 500mw ALL the time right... so I just thought maybe there's a reliability catch to this method because for me its a no brainier and I'm just confused why still so many people that fly 16SZ&crossfire use external battery or the internal mod method. Because this just seems like the perfect way to do it unless there's a problem with this method hahah just my thoughts... BTW I'm also talking about using 500mw with an upgraded battery not the stock one that lasts way less time.

The full size Crossfire modules can run up to 1W of power without an external LiPo connected to it. It is only if you go to 2W that you then need the external battery hooked up. Running 1W of power using just the internal transmitter battery will obviously drain the battery quite fast so just keep that in mind if you decide to do that.

BTW does any of you know what is the input voltage operation range for the 16SZ like what is the minimum and maximum voltage that the transmitter can accept

I'm using Lumenier 2100mAh 2S LiFe batteries and so far have not run out of power out in the field. But I stay out max a couple hours not an entire day. I do have 2 just in case.

Hi man!
It’s me again, I was wondering where did you get the special Futaba servo connector from? From my understanding their servo connector is a bit different than a “normal” one and it has like a small notch in the side. I can’t seem to find one online. Can you suggest any links where I can buy one from or maybe like one arrives with the radio when you purchase it.
Thanks in advance

Also is there a way to turn off the internal 2.4Ghz transmission when using crossfire? just to save some battery so it won’t transmit for nothing.
