Jkoch713 The interesting thing about this radio is the use of the Android system.
That is something that is very nice. It should allow many options for making your radio, YOUR OWN.


I started with a 4channel futaba FM radio Analog, Then Futaba 6 channel, and then a futaba 9CAP, Hitec A9 (1st affordable touch screen, and telem. radio in my opinion) Then the Futaba 18mz. Not to mention 6 dif. other SURFACE radios from various brands.
If I were to give anyone advice about picking up a radio is this:
For me, an expensive radio should DECREASE pilot work load, so he can concentrate on flying.
The MANY channels are great to be able to set up each servo from your radio(not using boxes in the wings ect)
I am not a fan of many switches, as this just clutters things up. In fact, I may remove the ones I don't use on my 18mz.

Futaba has a option called LOGIC and JR calls it Relate/relation. The use of this, is what really makes switches obsolete. John Glezellis does a great example of how this can be used in a IMAC routine in the SCALE Aerobatic section in the latest MA mag. OCT. 2014. He uses a JR18 for the example.
The downside to the Futaba 18mz or the prev. 14mz, is that it fails to show just how amazing this option is.
I hope the JR does a better job in there manuals... Not a deal breaker, just wanted to make you aware of this, as it is really great, but... takes some time setting it up properly to your liking..


I fly with my thumbs and all 4 fingers clutched around the back on the transmitter I can't fly with my index finger/thumb on the stick, and I have a hard time having my 2-index fingers resting on the front switches while I fly with my thumbs!...
So when are the Manufactures going to place PUSH switches in the BACK of the transmitter that can be reached with ones fingers w/o ever moving them during a flight?
Now I would buy that for a dollar!!

Cant wait to hear how this radio works, as the videos really don't do it justice!!!

Decision: I still like it! Makes me not care if I have to switch about 20 receivers out to a new operating system. Just a few will do for now. I always thought JR was missing the boat by using a roller instead
of a touch screen like on the 10X. Thank you JR for giving us back our screen. I guess JR's tag line will move from "Feel the Difference" to "JR.... The Touchy-Feely Flagship you wanna get your hands on!"

S Mullis I think the 28 would be great to own!Just imagine a six servo wing setup and two servos on each elevator, two to four servos on the rudder, throttle, choke maybe a onboard starter system for scale planes. On say a 3D or IMAC plane of 42% size each servo has it's own channel to fine tune. If using powersafe receivers that would be the gem. On bigger planes that have 3 servos per aileron two flap servos per flap, two elevator servos per side two rudder servos etc, etc. The possibilties would be endless with this transmitter. Now I have the DX-18QQ and I love it but to have this 28 would be great. Touch screen and all. DMSS protocol to boot. Retracts with scale doors in sequence all channels being independent. Have your smoke system on the throttle stick switch to turn on and off. Wow!!! Steve Mullis

Exactly. I don't see how a serial bus is any improvement over a power box really. Seems like a sexy thing that some people will pay for just to have it rather for any real practical reason.

Which brings up a question I've always had about this application in giant scale: How does a Futaba's serial bus handle the large current draw needed from a gang of high torque servos strung together on a 20-gage wire?

Sorry, might be going off-topic since I'm asking about Futaba, but it would relate to JR if they finally issue a true serial bus system.
If extra power is needed, you can power a group of servos with a separate battery, I do not think it is the most practical system, so I combine the regular ports on the Rx for the closest servos to the Rx and SBus for the ones on the tail for example, but I do it in F3A, which is not close to the same demand High Power servos need, the diagrams on both companies Futaba and JR sound good on the specs, but I gess it does depends on every specific application.

FWIW- If you have need for lots of servos which can't pull much current -say a glider - then the daisy chain makes sense.
frankly the concept doesn't make much sense to me- for my use.
The setups should be easy to trouble shoot and power draw to each servo should be tracable - in my book.
back to discrete leads from the receiver
To each his own

Futaba can be real Sbus or use decoders as JR does, and they can be combined also, Futaba been the forst on this, so no breakthru by JR.

I wonder what is JR coming out with to make it really XBus, so far is an incomplete system.

ULTIMATE1 I asked MattyMatt that same question and he told me the 11XG has better programing!That probably explains why a 14XG with receiver is $649.99 and 11XG is $799.99
